Somehow, my modem was hijacked, presumably during your service work done today. My modem's user name and password were changed to ANOTHER user's information. While having trouble logging in on my iPad, I saw the available networks no longer showed MY router name, but someone else's. I checked my tablet and phone and found the same with all. I then checked the router info through the TV and found another person's network AND their password now being MY network name and password. I reset the entire system and unplugged the modem to reset everything. I was able to get MY info back into the system correctly. HOW DID THIS HAPPEN AND WHY??? Now anyone else in the neighborhood that also had the same issues knows MY password information if the same happened to them as me!!!
