Hi Imran,

Try to set mss adjustment on the policy with source "wifi users" to Internet

you can set it via cli

edit "policy id"

set tcp-mss-sender 1400 set tcp-mss-receiver 1400

next

end

i use 1380 to 1400 and normaly is working fine

[MikePruett]

Yeah, I use 1366 as the sweet spot when I have traffic that is going over tunnels etc.

I didn't apply these .but i fixed my problem by doing the following steps

in fortiap profiles i created a new profile by deactivating one of the radio like i deactivated radio 1 and activated only radio two and entered the desired the ssid after that i applied it on one of the access point (Fortinet FortiAP 223B ) after that this AP is working fine and end user using this access point arenot facing slow speed issue
