The thread on weak signals reminded me that I posted a NIC
question and got no replies. But it was Christmas time.
Let's try again.
I installed a NetGear router capable of simultanous 2.4GHz
and 5.0GHz operation. I have some 802.11g gear so I can't
turn that frequency off on the router.
My wife's new laptop (Windows) connects in the 5GHz band.
My laptop (Fedora 16) had a 802.11g NIC card that I replaced
with an Intel 5300 that can also do the 'n' protocol at
either frequency. It does connect using the 'n' protocol,
but only in the 2.4GHz band.
Is there a way I can "force" the NIC to use the 5.0GHz band?
I've tried the several "iw..." commands that have arguments
to set frequency/channel and they "execute" with successful
status but to no effect.
