Subject: Re: 2.4GHz working, but 5GHz not working
Date: Sun, 15 Dec 2013 14:14:24 -0500 [thread overview]
Message-ID: <20131215191424.GA28861@node1.localdomain> (raw)
In-Reply-To: <20131214052157.GA5372@node1.localdomain>
Update:
It seems that my driver and/or the router don't like certain
combination of channel and its width.
- channel=36 and width=20/40MHz works -- I now remember this was
what worked before.
- channel=44 and channel=165 don't work at all.
- most other channels (didn't try all) work for width=40MHz only.
So, I'm now using channel=161 and width=40MHz.
