Model: Archer AX1500  
Hardware Version: V1
Firmware Version: 1.3.1 Build 20220401

I'm having issues with the 2.4GHz network disappearing randomly while the 5GHz network keeps working fine and at full speed.

 

It usually happens once every 2-4 days, but I had it occur up to three times in one day.

 

No devices can connect when it happens - tried on an Apple laptop, 2x Windows laptops, an iPhone, an Android phone, and various smart devices.

They either fail to connect with an error or pop up a password input even though the password is saved on all of them.

 

I've recorded a short video of the behavior using an Android WiFi analyzer app, but TP-Link's forum won't let me post the link.

I'll try and explain it in writing: basically, the 2.4GHz networks (both the regular and the guest one) show up for ~20 seconds, then disappear for ~10 seconds.

I'm doing the scan with my phone next to the router, and the analyzer app shows it at ~0m.

 

The things I've tried so far:

- Disabling the 2.4GHz network does nothing; it's still disappearing after re-enabling it

- I'm on the latest firmware if we don't count the withdrawn one from earlier this year which, by the way, I didn't install

- Changed the channels - tried 1, 6, 11, 5, 9, and Auto

- Changed the Transmit Power (all levels)

- Made sure "OneMesh" is disabled - I don't use it, and I understood it might cause similar issues

- Even did a factory restore

 

The only thing that fixes it (at least temporarily) is restarting the router.

 

I've had the router for ~2yrs and this only started happening 2 months ago, although I can't pinpoint anything that changed then.

 

Please tell me if there's anything I'm missing and I should try before throwing it in the trash and switching to another brand.

Hi,

 

It seems you have done a lot of troubleshooting yourself, and the router has been working fine for almost 2 years, so I guess you'd better contact the local tech support to be advised further and confirm if this needs to be replaced.

 

This is their contact info.
