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 :-) -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer."
