Rpi4 and NetGear A6210 (MT7612U) - long distance problem

Hardware Questions and Recommendations
1

Hi everyone,

I'm using a RPi since month as a router with openwrt.
I was looking for a cheap but good-enough USB wifi dongle to replace the embed wifi limited to 8 devices.

I bough a netgear A6210 (mt7612u driver). It work great with one exception.

As soon as I am at 15m (~50 feets) away from the router, my devices disconnect instantly without any reason, the quality connection is good (like 4/5 before disconnect)

Here's the disconnect/reconnect log (going away, going back) nothing suspicious I think

Try to set a channel which is as away as possible from interference.
If there is an option for maximum distance or optimize distance, make sure you make it at least twice the radius of the coverage.

I live out of town, so there is not much noise here.

Here a channel scan, Lord Voldemodem is my modem, Hogwarts Express the openwrt with the netgear a6210.

I'll try playing with the maximum distance setting tomorrow

Thanks @trendy

It should not be much of a problem, but you could shift the Lord a couple of channels higher.
Also for the sake of this troubleshooting, make sure that the phone won't automatically connect to the Express SSID.
Set the maximum distance and let us know how it goes.

Please check what is the signal strength for client device. It is possible that you see 4/5 quality on client device, but power received by A6210 is really weak so, under a stable margin.

Note that some client devices have limited power on higher 5GHz channels - please try lower channel like 36, 40, 44, 48 instead of auto

@lukasz92

Well, it is now disabled as I don't need it anymore.

make sure that the phone won't automatically connect to the Express SSID.

Done, same result

Set the maximum distance and let us know how it goes.

Tried 50, then 75, all devices disconnect at the same distance :frowning:

check what is the signal strength for client device.

Just before disconnection (in openwrt wireless page):
gnome-shell-screenshot-ZIOMT0

please try lower channel like 36, 40, 44, 48 instead of auto

I'm on 2.4Ghz, I have some IoT that need 2.4 :confused: so I can't change
But I fixed the channel to 6 where there's no other devices, devices still disconnect :frowning:

I also moved the devices to another place where there is less obstacle, same problem

At this point, I think it might be a driver issue, and the only workaround I think of is to use the embed Rpi wifi as a second access point, using the same SSID, maybe with mesh feature.

Could you help me to build this mesh configuration while we find the driver issue?

Thanks

Edit: Could it be due to the limited tx power? https://github.com/openwrt/mt76/issues/172
