MR1100 in a very weird state, no WiFi/tether, says name is AC81xS

I have a MR1100-2A1NAS that will not enable WiFi and I can never tether it on my Mac (although on PC I success). I've tried flashing generic then back to AT&T firmware to no avail. When making changes in the UI for WiFi nothing happens, it'll say restarting WiFi but refreshing goes back to Disabled and the LCD shows the same.

If I root it I can load /etc/init.d/wlan modules and then see the wlan0 interface, and if I run "dx -c Wlan.WifiSupported Primary" then it enables 2.4Ghz it seems. The other modes, I think "PrimaryGuestAux" (from memory) enables both bands in the UI, but the LCD will not show WiFi enabled. This does not seem to persist and things still aren't right overall after this and I usually have to factory reset to get back in.

The menu also shows the device name type as AC81xS which is very... generic. Haven't seen this before.

Any ideas of what is going on with this unit?

sounds like you need to load a full firmware back to it, I assume you are loading spk files? they are not full firmware think of them as more of an update file. someone may have loaded some files from another device to it, maybe the nv perhaps, this would explain the wifi not working as it depends on a "good" nv to work.

I saw the AC81xS on the admin portal after I run "AT!NVDEF".


Did a factory reset , it went back to normal.

What's the best way to do a full firmware load?

The best way is to erase it from 0 to 7ff then send a proper loader then send a proper hello and upon getting a proper response write it back from 0 to 7ff, then upon completion, your device will have 100% new firmware with all parts being written.
