The stock ROM (Lollypop but older version too) limit 5G WiFi channels to 36-48 or 149-165, or something like that, basically all US non DFS channels.
I figured how to connect the Shield Tablet to DFS channels.
It depends on the builtin WiFI module, which can be either Broadcom or Marvel.
My Shield Tabled came with Broadcom 4324 and by changing ccode inside the /system/etc/nvram_43241.txt (for other WiFI chips other nvram file applies) from whatever to ccode=ALL I am able to connect to mid band 5G channels.
BUT, for channels above 48, once connected to WiFi the controller cannot be connected anymore.
I need somebody who can help troubleshoot the controller issues with DFS channels on 5Ghz networks.
I can provide logs and whatever else might be needed.
