SD-WAN Performance SLAs showing link down on wifi that is connected.

[AskingForHelp]

Hello Community

I am troubleshooting a FortiWifi 80F with v7.2.4. There is Local wifi client connected to a network with -40dBM green signal strength. Next there is a SD-WAN Zone with that wifi as an interface which shows link is up.

However the Download and Upload all have 0 bps. The Performance SLAs shows the wifi link is down. To troubleshoot I followed the link below but that did not fix the issue.

Appreciate the help

Hi ,

The performance SLA down means the criteria you define in SLA are not matching like latency,jitter ect.

Please try to increase the value and test it.

Thanks

To troubleshoot the issue with SD-WAN performance SLAs showing the link as down on a FortiWifi 80F device:

1. Verify Wi-Fi connectivity.
2. Check interface settings in the SD-WAN zone.
3. Review SD-WAN configuration.
4. Validate SLA configuration.
5. Monitor network traffic.
6. Update firmware.

Tried to make the SLA Target easy to pass, but am not getting this to work.

Latency threshold 5000 ms

Jitter threshold 5000 ms

Packet Loss threshold 50%

Still the SLA details show link down (red arrow down)

There is other computers that are on this wifi without issue.

Hi Team,

> Could you please confirm if you are able to ping your sdwan performance SLA destination from the firewall?

> Please share the output of the below command:

di sniffer packet any 'host x.x.x.x and icmp' 4 0 a 

NOTE: x.x.x.x is the target IP you defined in the performance sla.

+ Once the above command is run, hold for 5-10 seconds and then please stop the sniffer using: CTRL+C

Please share the output!

Thank you!

Thanks for your help everyone. After adding aplink to the SD WAN Zone instead of wifi, the problem resolved.
