att fiber seems worse than my cable setup

[FireSuds]

I was ip passthrough seems slow and dmz isn't performing well either . And it's att anyone having success with att fiber can you assist me also in what reason would use the isp routers max addresses instead of the xr500

Could you expand on what the issue is you're having and what you mean by slow?

It's been a long while since I used ATT and Pass through, as it was during my stay at my brother's house.

But, From my understanding. I believe the BGH-210 is the gateway that can give IP-Passthrough efficiently, without many complications due to patches made on the other of ATT routers.

But, it is possible on other units.
