Simply put, a wireless network was set up with a network name and password in a senior community of primarily beginner users. Recently the name and password became changed to that of a community member named, let's say, "Joe". After addressing the router several times to change things back - only to find that the network name reverted to Joe - I changed the router password from admin to a unique pw and I confirmed that Remote Management was off. Next day... it was Joe again!
(Details are a Lynksys router connected to a cable company modem and with WPA2 security.)
Before approaching Joe, especially since I suspect he is no hacker but doing something innocently, I would like to know what I may have missed.
Thanks for any help.
