Model: Archer AX15  
Hardware Version: V1
Firmware Version: 1.2.2 Build 20250812 rel.75732

Hello,

 

I’m facing an issue with my TP-Link Archer AX15 router.

 

 

 

My 2.4GHz network loses internet connection every 2–3 hours and shows “No Internet,” but the Wi-Fi stays connected. At the same time, the 5GHz network works perfectly with no interruption.

 

 

 

What I already tried:

 

1. Restarted the router multiple times

 

2. Forgot and reconnected Wi-Fi on devices

 

3. Checked ISP line (internet works on 5GHz)

 

 

 

Devices on 2.4GHz suddenly can’t browse until I restart the router. Then it works again for some time.

 

 

 

Is this a firmware issue or settings problem?

 

Any suggestion would be appreciated.

 

 

 

Thanks in advance.
