Frimware Broke Router - 2.4ghz now showing channels 1 - 14; both wifi 5 showing 36 - 165. Help!

[Mittenz]

Reset Button, WPS reset method, GUI reset - nothing is fixing my router anymore.
Since upgrading to the new merlin, my wifi is no longer showing 2.4, 5_1, 5_2, im stuck and unsure what do to anymore.

I think the frimware broke the router somehow, as the 5_2 is now showing 160mhz in settings, the 2.4ghz band is showing 1 to channel 14, which is totally illegal.
It only allowed 1-11, and now its totally messed up.

Seeking assistance.

Also both wifi 5.0 5_1 and 5_2 have access to ALL channels (36 - 165)

Need help, sos!

It would likely be helpful if you list your router model and firmware you were updating to.
If you haven't done so already, try doing a hard factory reset as a troubleshooting step, after a hard factory reset; manually configure the router. Do not import a saved router CFG file.
Another troubleshooting step is to flash Asus stock firmware and see if the issue persists.

It is also possible, if you had AiCloud enabled you got hit by the malware that has caused various issues some of them involving WiFi settings being erase. Some who have been affected by the malware have indicated flashing Asus stock firmware fixed their issue.

More like attempted to fix damages done by malware wiping original configuration. Use whatever channels are legal in your country.
