Hi,
I’m having problems with installing USB wireless Edimax 7711UMn.
lsusb lists:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 046d:0817 Logitech, Inc.
Bus 003 Device 003: ID 7392:7711 Edimax Technology Co., Ltd EW-7711UTn nLite Wireless Adapter [Ralink RT2870]
I have also installed Gnome network manager based on the tutorila in one of the posts here, and when I unplug USB WiFi adapter, he lists only wired networks (after I left-click on it), but when I plug in USB, he also lists wireless networks and under wireless says “device not ready”
I have also read that I should write ‘dmesg | less’ and this is what I have found about my USB there

I have never installed or compiled any drivers, so can you please help me make my USB wireless work?
