I had problem with wi-fi with both 7.0 and 7.1 so now on 5.86 which works with out any issue..(Connecting to 2.4Ghz)
problem is with 13,14 channels! maybe also 12
if router transmit at this channels, then we cant connect.
i need to tune wifi driver to allow such channels.
stop posting. about wifi, i have no more time reading same posts all day.
