If two access points are within close proximity of each other, and running on the same channel as one another, can data be captured from access point A by an attacker on access point B?
I know if A and B are both close and on the same channel it causes interference, almost like an entanglement of the two networks. If this interference occurred would someone be able to capture the network traffic from the opposing networks machines?
I know its a weird question but a friend had an issue where his neighbors network was on the same channel as his and he was able to see his neighbors devices from his network. He thought he was hacked at first, but after doing some tests he realized his neighbors router was broadcasting on the same channel. He switched channels and the unknown devices dissappeared. Could an attacker exploit this?
