2.4G/5GHz Wi-Fi function stops after a while on Archer BE805(BE19000)
Hello.
I'm operating six routers of the this model.
In three units of six, 2.4G/5GHz Wi-Fi function stops after a while.
The time to stop is random, ranging from a few hours to several days after startup.
However, the 6 GHz band has not stopped and is operating stably.
* If the 2.4G/5G WiFi function stops, it will be restored as soon as the power is turned back on.
* This symptom occurs in both RT mode and AP mode.
* It appears to be occurring on routers with the latest firmware applied.
(WiFi did not stop on three Routers with firmware version [Archer BE805(JP)_V1_1.0.11 Build 20240318])
* No mesh Wi-Fi is used, all are stand-alone operations
Does anyone else have the same symptoms?

the reply that you provided is seems to be no resolution at all.
does it mean nothing that TP-Link can do because it is a hardware defect? Can we get the refund if so?
Kindly advise. Thanks.

I cannot say what the best option for your particular situation is. I am still within the retailer's return window, so I may take advantage of that if I can't figure out why WiFi disappears every 2-4 days while the wired connection continues to work.
The details I posted in the other thread were just to document the troubleshooting steps I performed in case someone else encounters the same issue.
That said, the router says it has been online now for 2 days and 15 hours. I don't remember rebooting it 2 days ago, but there are new log entries in the "Advanced" -> "System" --> "System Log" page:

I don't remember turning off the 6GHz band during the troubleshooting I performed while working with TP-Link Support. So my best guess is that this is a default setting in the beta firmware I was provided. I will wait for a few more days and turn it back on to see if the WiFi drops again.
Thanks!

Hi @odp_odp & @PavanR & @Shiro0
May I know, is there any update on your routers?
Could you please go to Advanced > System > Firmware Update, and click CHECK FOR UPDATES, you may see that the latest firmware 1.2.2 Build 20250424 rel.45837 has been released?
Please update to this version to see if the issue can be resolved.

Hi @Joseph-TP
I'm in Japan and have the same problem with my BE805.
The 2.4 GHz and 5 GHz signals drop out unexpectedly on a daily basis.
The latest firmware update didn't fix it.

Hi@liep9,
Thank you for contacting our community.
May I know when the issue started? Does the SSID disappear when the problem occurs? Have you enabled MU-MIMO? If yes, please turn it off for a try.
Please tell me what troubleshooting have you done? If the wired connection is stable, please try the suggestions for the wireless connection:
1) Make sure the Router is properly placed, it should be put in open area instead of inside a cabinet or shelf.
2) Change the wireless channel into another one. You may refer to Changing Channel and Channel Width on a TP-Link Router (new logo).
3) For 2.4GHz wireless client devices, adjust 2.4GHz channel width into 20MHz, for 5G wireless client devices, adjust 5GHz channel width into 80MHz or 40MHz to avoid interference.
