#22090: rt2800usb device will not operate in 11a/5Ghz mode
----------------------+---------------------------------------
Reporter: jmomo | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Designated Driver (Trunk)
Component: packages | Version: Trunk
Keywords: rt2800 |
----------------------+---------------------------------------
I have an Alfa USB 802.11 adapter using the rt2800usb driver which I am
trying to use.
The only reason I wanted to use it was for 5Ghz operation, but that
doesn't seem to work. Setting "option hwmode '11a'" in my wireless config
causes loading/starting to fail.
I have the proper firmware/drivers installed and it seems to work fine in
2.4Ghz/11g mode.
Notably, I get this error in logread:
{{{
daemon.notice netifd: radio2 (30357): command failed: Not supported (-122)
}}}

Take it upstream or is this an OpenWRT issue?
