I am using a wireless router for my wireless, which also feed a 4 port switch for my wire feed.
My USB modem plugs into this router.
Neighbours are half a mile away, and have probably never even heard of linux.
As I said in the preamble I have every indication of my wireless working, but it is not!!!!
I can add that I have tried several alternate live linux versions all with the same result.
CentOS6.2
Suse12.2
Ubuntu12.1
Kubuntu12.1
