Re: [PLUG] New Comcast wireless modem with old Buffalo wireless router

I always disable the wireless in the (vendor-provided) router.

If possible, just configure it to pass-through the external IP to the

LAN network interface on the router and then just configure your

Buffalo WAN to use that.

I've done that for both Comcast and Verizon in years past.

I've been a Comcast internet customer since 2012. Recently they told
me my old modem will longer be supported after January, and a few days
ago they sent me a brand new XB3 modem.

Currently I've got my old modem plugged into a Buffalo WZR-600DHP
AirStation running DD-WRT. I've got a desktop and a laptop plugged
into its RJ-45 ports, and it also handles a bunch of wireless devices.

I'm concerned because this new modem is also a wireless router. If I
just replace the old modem with the new one, will everything still
work? Or do I need to consolidate and move all my settings from the
Buffalo router onto the Comcast device? Has anyone tried this before?
I'm also concerned that if I mess anything up, the old modem will have
been deactivated and I won't easily be able to fall back once I start.

Thanks.
