BGW320 can't change LAN subnet?
I just signed up for AT&T Fiber yesterday, and they've given me a BGW320-505.
If I change my LAN subnet then it doesn't recognize its access code any more. So basically if I make that change then I can't do anything else after that. Is this a bug in my particular router or is it some weird AT&T policy? Why would they care what LAN subnet I use?
I would prefer to use my existing subnet because some of my devices have their IP addresses hardcoded in a few places.
(I suppose I could do this with passthrough to my existing router, but other than this one issue the BGW320 seems like a good device.)
