Since I am getting my Internet today, this probably isn’t such a big deal, but for the past few days I have been “borrowing” the coffee shop’s wifi below my apt. Comes on in the morning, shuts off at night. But, there are like 20 wifi points in the list to connect to. I hate ad-hoc networks, they just seem shady.
So, if you want to hide them from the list:
netsh wlan add filter permission=denyall networktype=adhoc
To reverse this again run the following:
netsh wlan del filter permission=denyall networktype=adhoc
