Using Asus Router with IP Passthrough on BGW320
I'm trying to use my Asus 802.11AC router instead of the ATT provided BGW320. I want to be able to change the DNS so that I can run a network-wide adblocking service.
I plugged in the asus router, connected it to the bgw320 via ethernet cable, went into the bgw320 settings and turned on ip-passthrough, gave it the MAC address of the asus router, and saved the settings. I turned off the 2.4/5ghz wifi connections on the bgw320 and set up the asus router to host the wifi. The problem arises when I try and connect to the asus routers wifi. Most of the time my computer tells me "Connected, no internet", and sometimes it will actually give me internet, but only for about 30 seconds.
I've already attempted to contact ATT support via the live chat, and they were not able to get it working. Not sure if I missed a step or what. Any help would be appreciated, and I can give more info if needed.
