Asus AX88u Strange behaviour after firmware update and main 2.4 ghz channel totally away ( GN 2.4 visible)

[Arnold_K]

My router rt-ax88u never had issues with this router until now.

Flashed Asus-Merlin 3004.388.10 alpha 1 no issues. After flashing Asus-Merlin 3004.388.10alpha 2 the issues occur.

My 2.4 ghz doesn’t come on.

Performed hard reset no result, at start up the 2.4 ghz wifi signal pops up and disappear.

Testing testing and testing no result.

Guest network created and the 2.4ghz GN works fine.

Creating 5 ghz guest network, 2.4 ghz network disappears.

Flashed Asus-Merlin 3004.388.10 beta one, no improvement.

I read a lot on SNB and I know there are radio issues with ASUS routers but the strangled thing is the following: the output of the wifi compared with my old RT-ac68u is very poor, and using a wifi scanner on my phone result into EDIGRAM as manufacture of my router ( never seen before).

(I am not able to place screenshts of these results, because the router I leave this disconnected)

My old router has to do now all the work (before I used this as a mesh-node)


Did some several flashes of older asus-merlin and asus original software but without result.



Anybody an idea what happening ?

You can try factory reset, power down, wait 10 min, power up, factory reset...repeat a few times. Go back to last known working firmware. Not alpha code.
Other option is to try recovery mode.
Manually config for testing.

CHeck the power brick while plugged in a while -30 min- hour . Cold ? Warm ? Hot ?

Thanks, I flashed the router with an old asusm old firmware but I also noticed a loose nut one of the antenna mountings. First what I saw was that 2ghz was visible but now 5ghz wasn't visible. I also performed a flash with the recovery tool. I'll try it later on next week but there is some progress.

a loose antenna might cause some issues, but should be across any ssid on that radio.

Yes indeed but the following occurs now when I follow your instructions.

At startup 2.4gh network is visible 5gh not visible.

When I give the channels different names like arnold24 and Arnold 5 then 5ghz sometimes pop up but after a while both channels are invisible.

Also seen now. I live in the Netherlands, my time differs from my location. I put nl.pool.ntp.org as time server and amsterdam, etc as location.

The rt-ac68u router doesn't give this message while it is the same network. The rt-ax88u which has the issues I configured as an ap at that ac router

I saw similar on my ol RT-AX88U.
Check the 5GHz MAC isn't zeroed out in the wireless log. How long are you waiting for 5GHz to come up (with certain wifi settings it can take 10 minutes)?
