It's very hard to offer comprehensive advice on a topic like this without a lot of background of the network and the configs of both the Fortigate and the D-Link and the ISP. Data traffic on UDP port 5247 is not encrypted. Flashing Green. Current_HWaddr 90:6c:ac:63:1b:29 l Unable to Telnet to FortiAP from controller/administrator workstation. State up Fortinet's Next Generation Firewall (NGFW) provides a secure and intelligent corporate network solution. Note that some issues are related to the keep-alive for control and data channel. The host does not reach the AP. The client could have roamed to another SSID. Configure the host/server to which CAPWAP traffic is forwarded: diagnose wireless-controller wlac sniff-cfg 88888, Choose which traffic to capture, the interface to which the FortiAP is connected, and the FortiAPs serial number: diagnose wireless-controller wlac sniff . How can I troubleshoot this? I am using two FortiWiFi 90D firewalls with software version . The site survey provides you with optimal placement for your APs based on the variables in your environment. Best practices for troubleshooting vary depending on the affected layer. TKIP is not the only possible source of decreased throughput. The following syntax demonstrates how to set the radio to sniffer mode (configurable from the CLI only). The problem I am facing is this, the fortigate sits behind the d-link modem which has max speed 24 MB/s. FortiGate HA Cluster. The radio signal from one AP interferes with, or cancels out, the radio signal from another AP. The capture file is only stored temporarily. Speeds are very much based on what the client computer can handle as well. Orange represents the Discovery . l Try upgrading the Wi-Fi adapter driver and FortiGate/FortiAP firmware. l The command cp wl_sniff.cap newname.pcap allows you to rename the file. The client has also purchased this max speed from the ISP. Use Application Control, Web Filtering, Traffic Shaping, and QoS to prioritize applications. Check the authorization status of managed APs from the wireless controller. Note the capture header showing channel 36; the beacon frame; the source, destination, and BSSID of the beacon frame; and the SSID of the beacon frame. This section includes information to help you identify and troubleshoot poor signal strength issues. The following image shows an example of a CAPWAP packet capture, where you can see the following details: The second recommended technique consists of sniffing the wireless traffic directly on the air using your FortiAP. The following command allows you to collect verbose output from the sniff that can be converted to a PCAP and viewed in Wireshark. The client transmits a week signal. Note that security must be set as a WPA-personal setting. APs usually have enough power to transmit long distances, but sometimes battery-powered clients have a reply signal that has less power, and therefore the AP cannot detect their signal. l Check the authorization status of managed APs from the wireless controller. Identify unwanted traffic, high-bandwidth web-related traffic, and use Security Profiles. You can perform a site survey using spectrum analysis at various points in your environment to locate sources of interference. Run Wireshark on the host/server to capture CAPWAP traffic from the controller. The recommended Signal Strength/Noise value from and to the FortiAP by clients is in the range of -20 dBm to -65 dBm. The command below creates a 50 MB file. This interface is connected at 10Gbps or 1Gbps with the correct cable and the attached network device has power. See the following illustration. Wireless is two-way communication; high power access points (APs) can usually transmit a long distance, however, the clients ability to transmit is usually not equal to that of the AP and, as such, cannot return transmission if the distance is too far. diag w-c wlac wtpcmd wtp_ip wtp_port cmd [cmd-to-ap] cmd: run,show,showhex,clr,r&h,r&sh. Hi all, Ive discovered that my FGT-500A on port1 that only shows active/blinking orange LED only. For a quick assessment of the association communication between the controller and the FortiAP, run the following sniffer command to see if you can verify that the AP is communicating to the controller by identifying the CAPWAP communication: diagnose sniff packet port 5246 4. Light: STATUS: Description & Suggested Action: PWR: SOLID GREEN: Power is on: UNLIT: Power is off: STATUS: SOLID GREEN: Normal: FLASHING GREEN: Booting up: HA: SOLID . l You may need to bring the interface up and down. Use WPA-2 AES instead. System_Device_Name wan Create a test file at a specific size and measure the speed at which Windows measures the transfer. You should also enable client debug on the controller for problematic clients to see the stage at which the client fails to connect. This interface is connected at 1Gbps or 100Mbps with the correct cable and the attached network device has power. Add to Cart. You also need to check basic settings like MTU size- if the Fortigate is running a higher MTU size than the modem you will experience fragmentation and speed/ connectivity issues. ), bssid ssid intf vfid:ip-port rId wId, 00:09:0f:d6:cb:12 Office Office ws (0-192.168.3.33:5246) 0 0, 00:09:0f:e6:6b:12 Office Office ws (0-192.168.1.61:5246) 0 0, 06:0e:8e:27:dc:48 Office Office ws (0-192.168.3.36:5246) 0 0, 0a:09:0f:d6:cb:12 public publicAP ws (0-192.168.3.33:5246) 0 1, diagnose wireless-controller wlac -c darrp, (This command lists the information pertaining to the radio resource provisioning statistics, including the APserial number, the number of channels set to choose from, and the operation channel. You can identify delays or lost packets by sending ping packets from your wireless client. Fortinet wireless adapters ignore signals of -95 dBm or less. Traditional Firewalls are dimming down: Next Generation Firewalls from Fortinet are shedding a bright light on network security. Use WPA-2 AES instead. If you want to get more than 54Mbps with 802.11n, do not use legacy TKIP, use CCMP instead. To solve an asymmetric power issue, measure the signal strength in both directions. The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges..

It is recommended that you match the transmission power of the AP to the least powerful wireless clientaround 10 decibels per milliwatt (dBm) for iPhones and 14dBm for most laptops. Link up To disable the sniffer profile in the CLI, use the following commands: If you change the radio mode before sending the file wl_sniff.cap to an external TFTP, the file is deleted and you lose your packet capture. If you can connect a PC directly to the "modem" then it sounds like it is running DHCP (and assigning the client an IP and DNS settings) and acting as a NAT router. It could have roamed to another SSID, so check the standby and sleep modes. The following example debug output is for the above command. For example, to disable the LEDs on FortiAP-221C units controlled by the FAP221C-default profile, enter: . Is this a problem on the interface speed or what??? and let the Fortigate act as the only router on your network. Created on The maximum output from a FortiAP shell command is limited to 4 MB. l All FortiAPs intermittently disconnect and re-connect. Sniffer mode provides options to filter for specific traffic to capture. Maximum firewall throughput is 950Mb/s and if you use full threat protection (which you should) maximum throughput is about 150Mb/s (depending on traffic type and mix). Created on The client might be de-authenticating periodically. Clients are not the only device that can fail to connect, of course. The client may need to udpate drivers. If you find that throughput is a problem, avoid WPA security encrypted with Temporal Key Integrity Protocol (TKIP) as it supports communications only at 54Mbps. This interface is connected at 25Gbps /10Gbps /1Gbps with the correct cable and the attached network device has power. You can also confirm the transmission (Tx) power of the controller on the AP profile (wtp-profile) and the FortiAP (iwconfig), and check the power management (auto-Tx) options.

The image below shows the beginning of the AP association to the controller. Capturing the traffic between the controller and the FortiAP can help you identify most FortiAP and client connection issues. If you want to save it, upload it to a TFTPserver before rebooting or changing the radio settings. Where 192.168.50.100 is the IP address of the tftp server. diagnose sniff packet port 5246 6 o l. The image below shows the beginning of the APs association to the controller. Try to connect from the problematic client and run the following debug command, which allows you to see the four-way handshake of the client association: diagnose wireless-controller wlac sta_filter 2. To this end, Fortinet offers the FortiPlanner, downloadable at http://www.fortinet.com/resource_center/product_downloads.html. The FortiAP reports the running results to the controller after the command is finished. Notice that you can determine the buffer size, which channel to sniff, the APs MAC address, and select if you want to sniff the beacons, probes, controls, and data channels. Enable wtp (FortiAP) debugging on the wireless controller for problematic FortiAPs to determine the point at which the FortiAP fails to connect: non 802.11 noise (such as microwave ovens). The FortiAP runs this command and then returns the results to the controller using the Control and Provisioning of Wireless Access Points Protocol (CAPWAP) tunnel. Ive tested to plug it to my PC and both LED is up. In the following screenshot, one of the clients is at 18 dB, which is getting close to the perimeter of its range. l Use 5GHz UNII-1 & 3 (Non-DFS) bands with static channel assignment for latency-sensitive applications. Sometimes communication issues can be caused by low performance. Even if the signal is strong enough, other devices may also emit radiation and cause interference. The maximum output from a command is limited to 4M, and the default output size is set to 32K.

MetaGeek Chanalyzer is an example of a third party utility which shows a noise threshold. The following image shows an example of a CAPWAP packet capture, where you can see: the Layer 2 header; the sniffed traffic encapsulated into Internet Protocol for transport; CAPWAP encapsulated into UDP for sniffer purpose and encapsulated into IP; CAPWAP control traffic on UDP port 5246; and CAPWAP payload. Use 5 GHz UNII-1 & 3 (Non-DFS) bands with static channel assignment for latency-sensitive applications. Create a test file at a specific size and measure the speed at which Windows measures the transfer. The Fortigate may then need to run PPPoE (for example) depending on how the ISP manages connections. Rx_Bytes 720292 The data itself is encrypted by the wireless security mechanism. The following syntax demonstrates how to set the radio to sniffer mode (configurable from the CLI only). 06-11-2007 Can someone tell me what can this be or help me troubleshoot this issue! It is important to note the messages for a correct association phase, four-way handshake, and DHCPphase. I have a fortigate 30E (6.2.4 firmware version) and I am experiencing problem with internet speed on it. You can enable or disable extension information at wtp-profile, and use the diagnose option below to print out the detail of extension information. Also, check the DHCPconfiguration as this configuration may be an IP conflict. Look for rogue suppression by sniffing the wireless traffic and looking for the connection issue in the output (using the APor wireless packet sniffer). The maximum client connection rate of 130 Mbps is for 2.4 GHz on a 2x2, or 300 Mbps for 5 GHz on a 2x2 (using shortguard and channel bonding enabled). The following elements are involved in the CAPWAPassociation: All of these element are bidirectional. All of these elements are bi-directional. If you do not see this communication, then you can investigate the network or the settings on the AP to see why it is not reaching the controller. end l Try to connect to the wireless controller from the problematic FortiAP to verify routes exist. The following image shows an example of the AP packet capture. Created on This is a common problem on a 2.4GHz network. l fsutil file createnew test.txt 52428800. available. A radio can only capture one frequency at a time; one of the radios is set to sniffer mode depending on the traffic or channel required. The following image shows an example of the AP packet capture with the following details: For a list of debug options available for the wireless controller, use the following command on the controller: (This command lists the information about the virtual access point, including its MAC address, the BSSID, its SSID, the interface name, and the IPaddress of the APs that are broadcasting it. Common causes of getting 100Mb/s connection rather than 100Mb/s are faulty Ethernet cabling or perhaps negotiation/ speed settings between the Fortigate and the modem/ internet device. LED specifications - FortiOS 6.2 - Fortinet GURU LED specifications - FortiOS 6.2 LED specifications LED status codes For more information about alarms, see About Alarm Levels. . The goal is to see how well the client is receiving the signal from the AP.

The second recommended technique consists of sniffing the wireless traffic directly on the air using your FortiAP. I would guess you are negotiating at 10meg and hence the orange light. Frequency interference is when another device also emits radio frequency using the same channel, co-channel, or adjacent channel, thereby overpowering or corrupting your signal. Organizations in any industry can weave security deep into their hybrid IT architectures and build secure networks to . Asymmetric power issues are a typical problem in wireless communications. Link/Activity. Created on Because your WAN interface is currently only 100Mb/s you will never get more internet speed than that. For high performance/high capacity installations, use lower transmit power to create smaller cells (set FortiPlanner at 10dBm TX power), but bear in mind that this will require more roaming. This issue can also be caused by a certificate during discovery response. This is a common problem on a 2.4 GHz network. The wan led is constantly blinking amber (speed) and blinking green for LINK/ACT. The FortiAP runs this command and then returns the results to the controller using the Control and Provisioning of Wireless Access Points Protocol (CAPWAP)tunnel. Common data link (MAC) layer issues include: In high density deployments, multiple APs are used, and each one services an area called a cell. There is a double NAT happening there and also the DNS is involved there too. The following image shows a network transfer speed of just over 24 Mbps. Speeds are very much based on what the client computer can handle as well. configure wireless-controller wtp-profile edit configure set mode sniffer set ap-sniffer-bufsize 32 set ap-sniffer-chan 1 set ap-sniffer-addr 00:00:00:00:00:00 set ap-sniffer-mgmt-beacon enable set ap-sniffer-mgmt-probe enable set ap-sniffer-mgmt-other enable set ap-sniffer-ctl enable set ap-sniffer-data enable. Common data link (MAC) layer issues include: In high-density deployments, multiple APs are used, and each one services an area called a cell. 11:22 PM, Created on The following list includes mechanisms for gathering further information on the client for Rx strength. In high density deployments, turn off SSID broadcast or turn down SSID rates. You must provide the site survey detailed information including a floor plan (to scale), structural materials, and more. For any wireless controller daemon crashes, check the controller crash log using the following command: Enable SSH login to the FortiAP device so that you can log in and issue local debugging commands: Try to connect to the wireless controller from the problematic FortiAP to verify routes exist. In the above syntax, the 2 captures the control and data message1 would capture only the control message, and 0 would disable it. (Former) FCT. If there is more than 10 ms of delay, there may be a problem with your wireless deployment, such as: If the FortiAP gives poor throughput to the client, the link can drop. Sample depiction of a site survey using FortiPlanner. The interference zone can be twice the radius of the signal, and the signal at its edge can be -67dBm. Run debug commands and sniffer packets. 05:44 AM. On the controller: diagnose wireless-controller wlac plain-ctl 1. The issue could be related to power-saver settings. tftp -l /tmp/wl_sniff.cap -r wl_sniff_remote.cap -p 192.168.50.100, ftftp -l /tmp/wl_sniff.cap -r wl_sniff_remote.cap -p 192.168.50.100, ftftp 192.168.50.100 -m binary -c put /tmp/wl_sniff.cap wl_sniff_remote.cap. So, if you have a 1Gb/s (1000Mb/s) internet connection (for example) you wont get more than 100Mb/s speed until the WAN link is also showing a "GREEN" Speed LED and your diag output shows "Speed 1000". This includes the elements of the CAPWAP protocol; the Request, Response, DTLS, Join, and Configuration (identified in color). Green. This is a step-by-step tutorial for configuring a high availability cluster (active-standby) with two FortiGate firewalls. You can download FortiPlanner here. However, clients may not have a transmit power strong enough for the APs to detect their signal. Another solution, if it is appropriate for your location, is to use the 5 GHz band instead. Major alarm. You indeed has clarified this very good. : fortigate vdom cli commands , fortigate show full-configuration without more, fortigate cli diagnose commands , fortigate cli console commands , fortigate commands cheat. If the DTLS response is slow, there could be a configuration error or an issue with a certificateduring the discovery response. Example of a successful AP and controller association: The previous debug command provides similar output to the sample debug message below for a successful association between the FortiAP and the wireless controller. All FortiAPs intermittently disconnect and re-connect. From your description it sounds like the D-Link "modem" is actually acting as a router. For analog sensors, alerts usually mean passing an upper critical (UC) or lower critical (LC) threshold. You can get similar tools from the app stores on Android and iOS devices. Another way to get a sense of your throughput issues is to measure the speed of a file transfer on your network. Try upgrading the Wi-Fi adapter driver, FortiGate and FortiAP firmware. It is recommended that you match the transmission power of the APto the least powerful wireless clientaround 10 decibels per milliwatt (dBm) for iPhones and 14 dBm for most laptops. The goal of this document is to provide you with practical knowledge that you can use to troubleshoot the FortiOS wireless controller and FortiAP devices. For more details, see IP fragmentation of packets in CAPWAP tunnels. The capture file is stored under the temp directory as. You must use two FortiAPs to capture both frequencies at the same time. Good luck- and if you any more specific questions I'm sure the Forum (and myself) will be happy to try and help. Your "diagnose hardware deviceinfo nic wan" shows that too- the "Speed 100" agrees with what the AMBER speed LED indication is showing you. A communication problem can arise from the FortiAP. To identify the difference, read the client Rx strength from the FortiGate GUI (under Monitor > WiFi Client Monitor) or CLI. When a wireless client sends jumbo frames using a CAPWAP tunnel, it can result in data loss, jitter, and decreased throughput. The Fortigate may then need to run PPPoE (for example) depending on how the ISP manages connections. WTP 0-FortiAP2223X11000107 Plain Control: enabled l On the FortiAP: cw_diag plain-ctl 1. The interference zone can be twice the radius of the signal, and the signal at its edge can be -67 dBm. Determine the best cell size for applications: For few users and low bandwidth latency sensitive applications, use high-transmit power to create larger cells. The following OSI model identifies some of the more common issues per layer. 06-08-2007 diagnose wireless-controller wlac -d [wtp | vap | sta], FortiWiFi and FortiAP Configuration Guide, WiFi &Switch Controller > FortiAPProfiles, WiFi &Switch Controller > Managed FortiAPs, Defining a wireless network interface (SSID), Configuring firewall policies for the SSID, Configuring the built-in access point on a FortiWiFi unit, Enforcing UTM policies on a local bridge SSID, Wireless client load balancing for high-density deployments, IP fragmentation of packets in CAPWAP tunnels, WiFi network with wired LAN configuration, Configuring a FortiAP local bridge (private cloud-managed AP), Using bridged FortiAPs for increased scalability, Protected Management Frames and Opportunistic Key Caching support, Preventing local bridge traffic from reaching the LAN, DHCP snooping and option-82 data insertion, Wireless network example with FortiSwitch, Configuring a FortiWiFi unit as a wireless client, Viewing device location data on a FortiGate unit, FortiAP CLI configuration and diagnostics commands, Best practices for OSI common sources of wireless issues, Professional Site Survey software (Ekahau, AirMagnet survey Pro, FortiPlanner). Check the controller crash log for any wireless controller daemon crash using the following command: Enable Telnet login to the FortiAP device so that you can log in and issue local debugging commands: Enable wtp (FortiAP) debugging on the wireless controller for problematic FortiAPs to determine the point at which the FortiAP fails to connect: Weak received signal, l WiFi capability: 802.11b, 11, 22, l Co-channel WiFi interference, l Side band WiFi interference, l Non 802.11 noise (microwave ovens). That was exactly what I was looking after. One FortiAP intermittently disconnects and re-connects. Any sensor, including sensors on PSUs, has generated an alert. The FortiAP is not connecting to the wireless controller. In the following screenshot, one of the clients is at 18dB, which is getting close to the perimeter of its range. If the client connects, but no IP address is acquired by the client: Check the DHCP configuration and the network. For example, a temperature has increased above the allowed operating temperature range. It sounds like you have proven that it is a Fortigate setting you need to look. So if the DTLS response is slow, this might be the result of a configuration error. Use DFS (Dynamic Frequency Selection) for high performance data 20/40 MHz. However, these cells can cause interference with each other. Note that security must be set as a WPA-personal setting. Fortinet is the pioneer of secure networking, delivering flawless convergence that can scale to any location: remote office, branch, campus, data center and cloud. You can measure the link throughput or performance between two devices by using third-party application tools such as iPerf and jPerf. For a comprehensive list of useful debug options you can use the following help commands on the controller: (this command lists the options available that pertain to the wireless controller), (this command lists the options available that pertain to the AP), (this command lists the information about the virtual access point, including its MAC address, the BSSID, its, SSID, the interface name, and the IP address of the APs that are broadcasting it), bssid ssid intf vfid:ip-port rId wId, 00:09:0f:d6:cb:12 Office Office ws (0-192.168.3.33:5246) 0 0, 00:09:0f:e6:6b:12 Office Office ws (0-192.168.1.61:5246) 0 0, 06:0e:8e:27:dc:48 Office Office ws (0-192.168.3.36:5246) 0 0, 0a:09:0f:d6:cb:12 public publicAP ws (0-192.168.3.33:5246) 0 1, diagnose wireless-controller wlac -c darrp, (this command lists the information pertaining to the radio resource provisioning statistics, including the AP serial number, the number of channels set to choose from, and the operation channel.
