Hello all, sorry for all the issues caused by this Archer C6 and it takes long for a fix.

Edit 2020-09-23: Our developer has provided a new beta firmware for the Archer C6(EU), please try to update your router firmware to this version and monitor its performance if you still encounter the disconnect issue:

If there is still no improvement with this latest version, please confirm basic info as below:

1. What is the exact issue now, is the 2.4G wireless still unstable or 5G unstable or all 2.4G/5G/Wired connections are having issues?

2. Are all wireless devices or both wired and wireless devices experiencing the same dropout or just some special or old clients? When they got disconnected, is the wireless network of the Archer C6 still broadcasting or the wireless network is no longer available on all other devices as well?

3. If only the 2.4G wireless is not stable, try to modify the wireless settings on the Archer C6 first, such as wireless channel, channel width, which would help in some cases:

4. Please try to fix the 2.4GHz wireless swcurity to WPA2-PSK(AES), then restart the C6 and confirm again:

Thanks again for your time and patience. Let the community know if there is an issue.

Hello, thanks a lot for your detailed info, and thanks again for all of your efforts struggling with this issue on the Archer C6.

May I know how many wireless devices are connected to the 2.4GHz network out of 22? Are all 2.4GHz wireless devices experiencing the same dropout or just some special or old clients? When they got disconnected, is the 2.4GHz wireless network of the Archer C6 still broadcasting or the wireless network is no longer available on all other devices as well?

What kind of "heavy" use do you have on the local clients?

Thanks.

I have the same symptoms like Kubas.

But When i disable the 2.4ghz guest it runs stable. 2.4ghz is not heavy used but 5ghz is has more clients and sometimes under heavy load with many videostreams and so on. 

Is it something like overkill for this router ?

In my case 10 wifi clients, 7 are 5ghz.

5 clients over LAN, but not direct connected at the C6.
