BGW210 access code

Before you try a factory reset (hold down the reset button for >15 secs) on the BGW. take a picture of the Access Code so you can zoom in and make certain the characters are what you think they are.  We've seen things like two slashes next to each other ( \/ ) so it looks like a V.

If you do go with the reset then note you'll have to re-enter any changes you made to the BGW.

Finally, if neither of these things work, call 800-288-2020 and request a replacement gateway.

I am reasonably confidant that the character string that I saved in my password manager and that I tried both by manual typing after re-inspecting the label and copying and pasting from KeypassXC used to work a few years ago shortly after AT&T sent me this gateway.  I had a lengthy conversation with an AT&T technician that eventually led me to the conclusion that AT&T has 'locked down' the gateway for 'customer security' so that whatever advanced configuration is 'admissible' has to be done by an authorized company technician who has the required security credentials.  That also allows AT&T to charge a monthly fee for 'services' such as having a 'static IP address' even in a private address space as well as a public address space.  If a factory reset is needed and I am right about AT&T having changed the Access Code, then using that factory reset would just open another can of worms. 

That's ridiculous.  If there's a "lockdown" of the gateway then you've got the only one in existence.

Agree with tonydi, if the password on the label doesn't work, then it was changed.  A factory reset will put it back to the value on the sticker, along with resetting every other value you (and/or the person who changed the password) may have changed.

I normally make a note in my password manager whenever I change a password, but there is a small chance that a note got lost if it wasn't made in the master copy of that file.  That and the fact that the AT&T Tech wanted to charge me for giving my home printer a "Static IP Address" possibly by some more robust procedure than just assigning an address outside of the DHCP range, (if I can see what the DHCP range is actually set to), and the fact that the technician thought that he could still make configuration changes even though the password was changed are the main reasons that I suspected that it was AT&T that changed the password.

There’s no reason to change the default access code, especially if you’re using a password manager.
