DARRP Wireless

[kanes39]

Hi All,

I am in need of some expert advise on this after exhausting Forti TAC support.

Details:
FW: 7.2.4
AP: 7.0 Build 0031 (latest).

H/W: U231F

Problem: The AP's are all using the same channels and because of that when users are roaming they get disconnected and I have to either reboot them or put them into a different AP profile and limit the channels they can use so that each AP uses different channels - this is particularly for 5Ghz.

I don't understand why even with RRP - Enabled and DFC channels selected the APs are selecting the same channel and I can confirm the AP signals are overlapping so why is the AP not smart enough to move the AP's to different channels?

Can someone please guide me on what am I missing here and Forti-TAC's suggestion is to create an individual profile for each AP and enable RRP but limit the channels or make sure they don't overlap.

Your help is much appreciated.

Wireless Controller,  #firewal

How many clients are associated to AP-02? Do you have limits configured?

Have you tried factory resetting the AP?

Hi Graham,

Thank you very much for your assistance and the command that you shared.

I was able to prove from that command that the DARRP was not working at all because it had no values on the RSSI and Inteferences.

Its all fixed now with the help of an engineering version Forti OS.

Thanks again for all your help.

Hello! Nice to meet you.

I'm having the same problems you described in this thread. Could you please tell me what your final solution was?

Thank you very much.

Hi @irixis,

I did go through a lot of changes in the environment to fix this issue.

However the good news is that there is a fix for this issue on the latest firmware for the AP.

The current firmware we are using would be 7.0 build0146.

Other things that I did to stabilize the wireless network:

1. Disabled AX band.

2. Enabled Frequency handoff and AP handoff.

3. Disabled WIDS.

4. Disabled 2.4Ghz for SSID's that does not have any old devices.

5. Reduced the power for the 2.4Ghz as that was causing some issues.

6. Updated Transmit power for 5Ghz.

7. Updated channel width from 40 to 20mhz.
8 We had 12 AP's and we create 2 AP profiles with 6 AP's in each profiles. Statically assigned different channels to this 2 groups.

I did many more but really can only recall this things.
