RT-AX88U wireless shuts down at irregular intervals

[Nighthawke70]

ASUSWRT-MERLIN 3004.388.8 Stock, no major setting alterations have been made.

I had recently updated to this version and now my radios shut down at irregular intervals. Just the radios, the LAN stays live. I am forced to do warm reboots or cold boots via the switch in the back of the router. I triple checked to ensure I didn't get the PRO version of the firmware.

Here's the wireless logs post-reboot +2 hours. If you can make heads or tails out of that you are welcome.

How soon after the major version update?

 

[Logi]

1-2 days

 

[Nighthawke70]

Did you do a factory wipe before the upgrade? I did not.

 

[Logi]

No, never do, from Merlin to Merlin

So far, is a one time event

 

[Nighthawke70]

Hmm, a major jump might require resetting to factory defaults before the big hop. I hate to, for i got a ton of static IP assignments and other custom settings that the save does not catch. Pity.

 

[jerry6]

What FW version did you upgrade from ? might be worth trying , can't hurt

 

[Nighthawke70]

388.1 Ouch. I just got the PRO model of the 88. I might bring that up then tinker with this older unit for mesh work.
