Somebody made an unauthorized wifi extender, which has the same SSID than the network I connect, but is crappy, slow, unreliable, and rarely works.
The only way I can connect to internet, is to the original wifi router.
I use software like netsetman, to pick the right wifi, but it frequently fails and connects to the wrong one.
There is any way I can ban my PC from connecting to the wrong wifi by his MAC address?
I'm asking how to block my PC from connecting to the mac address of the extender.
I use windows 7 64b
