Hello
There was similar topic "requires more rates than we support"
Some investigation
ROS: 6.49.1
RB: mAP lite
WLAN mode=station
If I choice "band=2ghz-b/g/n", it connect to ew MT, iphone, android AP etc. Correct
If I choice "band=2ghz-g/n" (without "B"), it connect only to MT AP. To other AP it not connecting with debug: "wireless,debug wlan-WAN: XXXXXXXX requires more rates than we support". Even if iPhone, Android broadcast "g" network
I don't know if this is a future or bug. Just I leave it for info
Setting "band=2ghz-b/g/n" fix connection problem to any APs
Best
