you may want to log into the router and just use Narrow 20mhz range - , currently its set ot wide/40mhz and you have 2 channels
i cant see the adapter make and model on the xirrus screen shot -
Gigabyte GA-WA770-US3 does not come with wireless - so not sure what wireless adapter he is using
connect to the router directly with a cable if possible - i know that may mean moving the desktop - but if it works fine on a LAN connection, then at lease we know its a wireless issue only
if it does not work on a LAN line either - than we will need to investigate further
Are other PCs connected to his home wireless all working fine ?
