[SOLVED] Unable to Start WRT1900acs 5GHz Radio

Installing and Using OpenWrt

Just flashed today after going through and inordinate amount of pain trying to handle VLAN Tagging in DD-WRT, sadly now I cant get 5GHz running :confused: any ideas what I might have done wrong?

openwrt-19.07 branch git-20.057.55219-13dd17f / OpenWrt 19.07.2 r10947-65030d81f3

Did you try with the channel set to auto?

I've tried Auto, 149, and 153.

radio1 is 2.4 GHz only, but you try to configure channel 36, which would be a 5 GHz channel. mwlwifi is known not to work well with DFS channels, but ch149 on radio0 is one of those (I think, don't have regdom for AU handy at the moment), so try to use a non-DFS channel first (ch36-ch48).

I thought so at first, but then realised it's the txpower. But then again, that's an invalid value for AU.

oops, you're right.

I've now tried setting everything to Default + Auto and 36, 44, and 48, I've also tried these values with 40MHz width as well as 20MHz, still no joy

Have you tried starting from scratch? Basic default settings, only change to enable radios.

I am thinkjng in line of a missing setting (like txpower for radio0) or a typo or a hidden char making some UCI line invalid.

Try deleting /etc/config/wireless and rebooting. The file will be regenerated. Start with minimal changes. Just enable radios, then try them without encryption, then start adding parameters.

I deleted the 5GHz wifi interface, added it back, then rebooted and its now working.
