I moved into a new place and the previous owner gave me their 3801hgv gateway router.
The original wifi key sticker is still on the back. I had service started with AT&T. However, I want to change the wifi key.
How do I do that if I dont' know the gateway router's password? The previous owner had no idea because they never bothered with it. They told me that they had given the wifi key to some neighbors because their cable internet was down. That's why I want to change the wifi key, just in case those neighbors see the router up and use the old key to get access.
I've called AT&T customer service twice today, but I gave up after lengthy holds. (40 minutes the first time and 55 minutes the second time)
Can anyone help me figure this out?
Thanks!
