and when you just use Scan do you see other networks?
you can check your router now - it should be working as we placed a fix there.
I've make test fixed 4.04 with 4.03( the same cards). From 4.03 to 4.04 data transfer with normal rate, from 4.04 to 4.03 data transfer with rate 10-50 kb. Signal quality show 95-98% in two way. With nstream don't working- every time disconnect- data lost. So if you will place fix to other router you will test it together. See mail.
