Model: Archer BE230  
Hardware Version: V1
Firmware Version: 1.2.5

Hi,
I have problem with WiFi 2,4GHz (normal 2,4 GHz and IoT) after FW upgrade. Before everything worked great. After upgrade my WiFi 2,4Ghz is stopping work after a while. (after 2-6H). 
Network is visible but none of my device can connect. I don't change any configuration except upgrade. I performed factory reset but it doesn't help, now I am testing downgrade to previous FW.

5Ghz network works fine.

I don't know if this is a hardware issue or FW issue. Please help how can I check it and solve my problem.

Hello @kulik555 ,

Welcome to our community.

 

May I know if your network topology diagram is as follows:

ISP modem—BE230)))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

What if you enable the 2.4 GHz guest network? Will it lose connection in 2-6h?

Have you downgraded the network back to 1.2.1? Can the 2.4G work properly? If yes, please help collect the backup file and system log file.

Yes,
My topology is as follow:
ISP modem or router—BE230)))((( client devices

After 24hours on downgraded FW everything looks ok. I noticed that throughput is also better on older soft ( 1.2.1 ). 
I will give some more time for testing, but I think the newest FW is somehow broken.
