Comcast router in bridge mode

We have an ASUS rt-ac66u which has aicloud so that we can access out usb drive for media from our own cloud. This is connected through a comcast Arris 862 gateway / router.  We previously had the comcast unit ins bridge mode to allow a public IP for the Asus router.   Something has happened that has taken our router out of bridge mode. we called and a tech which at first try, did change the settings so we momentarily had a public IP, but then she activated the wireless router funcion.  When she tried to turn that off, we are back to 10.0.0.3 in the Asus.  Tried to sell us Signature support - just want the comcast unit set back like it was.  Any ideas to "help " a tech through this process ? or another avenue to take ?

FWIW, here is what they need to do to for them to enable and verify that the modem is in full bridge mode.

For the Arris devices bridge mode can be enabled in 2 ways. There is a 1 button GUI click method, and there is a way for them to log into the Arris modem management page to enable the bridge mode. Not the Xfinity management page by the way. So if you call in to have it bridged and your wifi light is still on after that, they have done it wrong.

You need to have them go into the Arris management page and then go to Advanced (requires password of the day) --> MSO features --> then

Bridge Mode -- Enabled
Wifi - Disable
LAN DHCP - Disable

then have them reset the modem. If they dont follow those specific steps chances are your modem isnt fully in bridge mode and you may continue to have problems.

Then after emta is in bridge mode, I can just connect "any port" on the gateway to the wan port of my router?

 

Just searching for info while waiting for the Comcast gateway; guess CC is now only sending gateway type modem/emta for D3.........

 

Forgot to add that I haven't seen any "permanent" FAQ for howto/use the EMTA gateway yet.

Re: Comcast router in bridge mode

Only LAN port # 1 should be active after the gateway is bridged.
