Picked up the SB6141, got TWC to do what they needed to do and now I'm up and running how it was intended....with a dedicated modem and a dedicated router. Played a few matches tonight and not a single hiccup (multiple reconnects and teleporting last night), ping to east servers is down around 42ms (~53ms last night) and my console is now getting ~100% signal from my better router (~80% with the old one).
Hopefully it's all a sign for the better.
Win!
I very seldom like the modem+wireless combo things, and it's the worst when you're stuck with one that doesn't really have a bridged mode option to run it without the routing functions.
There are some things we could do to your router to improve performance even more :
(1)- Get this :

(or an equivalent if you have an iphone instead). Find the least busy channel you can.
(2)- Change the wireless channel to the least 'busy' one using the above app.
(3)- Look at this video :

*- set up a username/password if you haven't already
*- try disabling QoS if you have it on (Buffalo sometimes calls this 'movie engine'), it artificially limits bandwidth use to reserve data, which introduces additional processing delays, and that can increase lag in gaming
*- try testing to see if you get better (non-gaming) results with an alternative DNS, OpenDNS and Google DNS make for some nice options there
*- TURN OFF the auto-setup option (AOSS/WPS), this is a
big security hole in modern routers. Make sure you have WPA2, AES and TKIP are both fine. Everything is hackable, but leaving the auto-setup 'push-botton' connection option makes hacking ludicrously easy (and some routers don't actually turn if off when you set it off, but that's a different story).
*- If you want another tiny step towards the absolute minimal delays, you can set your XB1 up on a static IP, just choose an IP that's out of the DHCP range on your router. Then go to the firewall section of the router and place that IP into the 'DMZ'. This bypasses port processing basically for that IP, a small additional step that will increase the raw speed/latency efficiency for your connection to the XB1. This can also be done on PCs as well, but typically a router only allows a single DMZ address (don't use it on PCs with outdated security, but the XB1 itself will be more than fine without sitting behind the router's broadband processing).
*- If you get really into wanting the absolute best from your Buffalo, give a shot at learning DD-WRT :

It can be daunting at first, but it opens up a ton of options not available in the Buffalo firmware. Basically think of a Router as having a CPU, an OS, Memory, and a Radio. OEM Firmware (the OS) can vary drastically, and even though a router's CPU (in your case a 400Mhz Atheros) and memory (64MB) might be quite good. Also, the stock firmware might limit your signal strength from what the radio is capable of. In the best cases, a $100ish router can be turned into something better than what normally costs 4-5x or more that price.
I hope that helps some, take a break between blowing things up and check it out
