Since a few weeks, someone is regularly running a wifi network copying the SSID and BSSID of my private router, resulting in some anoyance, due to being kicked out of my own network from time to time. This is especially annoying, because for some unknown reasons, my devices won't connect to my wifi for quite some time after changing its SSID. Also connecting to the fake access pints redirects to a website resembling the login page of some Wifi-hot spots, asking me to log in via my password. Altough i certainly won't use my password there, i don't wanna have to tell every guest, not to use the password there.
What are my options? I would prefer not to have to spend too much time or money on that issue, so buying a router able to change it's BSSID is not my prefered option (also i'm not quite sure wheter that would help)
Triangulating the source of the spoof with my smartphone did not work well, due to urban environment.
