this is not wrong, but nearly all adapters support wireless to
the very
old 801.11b for compatibility. so if an adapter support 5ghz,
he will in
99% also support 802.11a but if he supports 802.11n 5ghz is not
mandatory
Ah, so it *might* support 5GHz... :-( Thanks.
you can also post which chipset your notebook uses, but most
devices
only support 2,4ghz
Oops, I forgot; "lsusb" plays its cards close to its chest, but
I found
this in "dmesg": Atheros AR9565 Rev:1. After some searching, I
see that
it doesn't do 5GHz...
Will trade Acer Aspire E-15 for a Debian-compatible laptop if it
does
802.11a :-)
