no problems with 5Gz so far with 1.3.0 / 1.3.4, but unfortunately I cannot say that exactly

2.4Ghz e.g. the shelly relay Switches and the Nest hello lose the connection after a few hours.

Also some Xiaomi Yeelight bulbs  lose their 2.4 Ghz connections

1.3.1 beta is ok but not as stable as the 1.2... Versions

When I use Mikrotik as client to 2.4GHz on Archer A6/C6 eventually it looses connection and while trying to reconnect client logs "authentification timeout". At this point 2.4GHz SSID is still visible but not accepting any connections. 5GHz continues to work without a problem. This problem can happen after few hours or after dozens of days of uptime - the range is huge and pretty random. It is all true for all firmwares upto 1.3.0. The latest firmware I am avoiding for now.

AVM Fritzbox is a very powerful Router

Memory:    RAM: 512 MB - NAND-Flash: 512 MB
CPU:    Seale GRX550 @ 1000 MHz - MIPS32 / InterAptiv 34Kc - CPU-Cores: 2

Load ballancing is working fine most of the time, wireless clients are distributed

e.g.

Fritzbox - 8

Archer C6/1 - 20

Archer C6/2 - 15

BTW. I don't understand your question! Everythings was working fine before update to 1.3.0 and later!

Thanks 

Menwhile I received an email with a link to beta firmware I'm using for weeks.... as I have wrote in some threads 

Is this the further debug or troubleshooting?

Kind regards

Very interesting.  This chimes with my experience of an old TL-WR841N that I was using as a switch and WAP that I eventually recently replaced - it would go for days before suddenly becoming unresponsive on the wireless (wired was fine).  My router in London is a Vigor 2862.

The problem we are experiencing might have existed in the code for a long time.  It's just that, as I am now using the C6 as the main router in Brussels, it isn't really feasible to just reset it each time.

This would perhaps explain why the 2.4 GHz drop-out only be came an issue earlier this year, having worked fine last year.

Hi, i have this same problem. I see problem in fw too. All problems begin after upgrade firmware. 

Please any Solution. 

Thx

Hi all,

I am coming with same trouble on wifi 2.4Ghz, after approximaty 1 day wifi crash. All device on 2.4Ghz are offline (like IOT). 5Ghz still working.

Need to reboot the access point.

So can it be fixed by firmware update are is it definitely a hardware problem ?

firmware : 1.3.4 Build 20200512 rel.51608(4555)
