Posted: Thu Jul 09, 2020 17:39 Post subject: Pheww ... that was a Marathon
So I have the Firmware: DD-WRT v3.0-r43516 big (06/25/20
running atop CFE220.127.116.11 ( bl_version=18.104.22.168 )
And .... both 2.4Ghz and 5 Ghz radios are working.
In overview the sequence was:
1: Reflash back to ASUS 22.214.171.124 (actually quite new)
2: Use ASUSWRT to reflash to Merlin (NB both wireless active)
2a: check CFE level, it's still on 126.96.36.199. (so the ASUS flash didn't update it)
3: Upgrade CFE
4: reboot (still Merlin) helpfully Merlin shows the CFE level as part of it's status/version screen (DDWRT does not?)
..confirm now on CFE188.8.131.52 (2014 vintage !)
5: Use upgrade (GUI Button) to DD-WRT v3.0-r43516 big
6: Manual power-cycle + WPS switch to clear RAM
This is by no means a full set of instructions. Each part has instructions elsewhere, it's just an overview of the maze.
(I need to make updates in a few more places to make this issue clear)
