Flint 2 Wifi dropping on one PC/

Hello everyone

I got a flint 2 for christmas and have had one of my PCs randomly disconnecting from it.

I’ve updated it, just haven’t tried the openwrt build or anything else.

There’s this message in the luci syslog every time it disconnects:

There doesn’t seem to be any pattern, as it has happened at intervals of 5- 10 minutes.

If anyone could just decode some of that and put me in the right direction that would be awesome.

Thanks

Could you please provide some information about your Wi-Fi settings and about the client that gets disconnected? What Wi-Fi hardware is it using?

Currently on EndeavourOS (an arch derivative) using:

Network controller: Qualcomm Atheros AR93xx Wireless Network Adapter (rev 01)
Subsystem: Qualcomm Atheros Device 3112
Kernel driver in use: ath9k
Kernel modules: ath9k

as a network controller. And here are my settings

Thanks for your help.

First thing I would try is changing the WiFi SSID name to something simple without spaces and special characters.

You can also try disabling Randomized BSSID for both radios.

I would also scan your local networks to see what channels they use for the 2.4ghz network and choose either 1,6 or 11 based on which has less SSIDs on, you can use either an android app or iOS app for that.

The 2.4 channel would probably be best set to 20mhz too as 40mhz can also cause issues.

Setting your 5ghz channel outside of a DFS station will also help, I'm unsure if when left on auto if the channel could potentially go to DFS frequencies. So choose Non-DFS Channels for the 5ghz band. Start by choosing channel 36 for 5ghz

The channel width for your 5ghz is also set to 160mhz, if you don't have clients that can utilise that then you can lower it to 80mhz too but start with the other suggestions first.

Thanks for your help, unfortunately that didn’t help.

I’ve even changed to 4.8.3-op24 and I still get this:

I’m not doing anything internet intensive, just watching youtube, and this will happen at random intervals.

Hmm is your flint 2 direct connected not on a switch or something or not on daisy chained switches?

Do you use patch cables too?

What i get from your ping log, is the suspicion of a layer 2 issue somewhere in your network.

Bad cables can be a cause on top of this hidden issue.

Switches have priorities, if they are not set properly the wrong switches can be seen as the main switch.

And with a bad cable it can also cause bdpu changes on the topology, my bet is if you actually enable STP you will lose all connection or that maybe already have happened?

If you choose 160MHz bandwidth on 5GHz you are automatically on DFS-channels (in EU). Choose 40 MHz (channel 38/46) or 80 MHz (channel 42) bandwidth.

Using of DFS-channels may cause regular interruptions.
