My Gateway spontaneously reset itself to factory defaults in the middle of the night!
My BGW210-700 gateway spontaneously itself reset to factory SSID and password in the middle of the night!? No power failure had occurred
Woke up to find all my hard-wired and Wi-Fi devices had lost connection.
Fired up my AT&T Smart Home Manager phone app to find the gateway SSID and password were set to factory defaults! I changed those back to what I had set them to, and everything seems to be working.
After 45 minutes of calling multiple 8nn phone numbers, fighting my way through the inane AT&T voice-bot, and support "techs" with accents over very poor quality connections that I couldn't understand clearly, and who didn't understand what happened, I finally got an English speaker on good quality connection who verified the spontaneous reset. AT&T is sending me a new gateway.
How and why did this happen? Anyone else experience this?
