Model: Archer C5400  
Hardware Version: V2
Firmware Version: 1.2.5 Build 20210308 rel.64655(5553)

Wi-Fi 2.4GHz having issue, mainly I set this frequency for all my smart devices.

After a while they all disconnected using this firmware 1.2.5 Build 20210308 rel.64655(5553).

When I checked the router the Wi-Fi was not enable and it's off for 2.4GHz.

For 5GHz-1, I turn it off and 5GHz-2 it seem to be fine.

 

I also try to enabled the Guest SSID with same setting with configuration, it seem doesn't work good either.

 

I don't know if TPlink support itself know this issue and address it the issue of this router or not.

So many product they release not even one is stable.

Judging by the firmware version itself there no fix until now, very frustrating and very disappointing.

Hello @Xarsage1,

 

Please try the following troubleshooting suggestions to see if you can make the 2.4G work stably for the smart devices:
1. Modify the 2.4G wireless settings, such as wireless channel, channel width, and security, you can try different combinations. Try to change the 2.4G wireless security to WPA2-PSK TKIP, save and reboot the router to confirm.
2. Schedule the 2.4G wireless, set an off time when there is no need for the connection.
3. Reset the router to factory defaults, reconfigure it from scratch, then monitor the stability.

 

However, if none of the above helps, it could be a hardware issue and it needs to be replaced, please check the local warranty policy for details or contact the local tech support to be advised further:
