*EXTREME LAG OVER XBL - Solutions?

With respect to playing MW2 Multiplayer and SpecOps...Lately, I've been experiencing multiplayer lag that's so bad that I often find myself booted from matches or I get stuck in a situation where I have to leave games because matches are utterly unplayable (jumping all over the map with no control of my character).

There are two schools of though here: 1) millions of MW2 players are slowing down gameplay and this will eventually pass in time, or; 2) my ISP (Comcast, Washington DC) and/or network hardware set-up is to blame.

Assuming the latter to be the culprit, I contacted Comcast (Washington, DC) to see what was going on from there end (if anything). They reported no issues from their end and told me that my download/upload speeds should be around 13Mb/3Mb per second, respectively. After running my own speed scans (speedtest.net), I was consistently getting from 11Mb/2Mb and 13Mb/3mb, download/upload so what Comcast was telling me was consistent with reality.

Right now, my Xbox 360 is plugged directly into into my Linksys WRTG5 series Wireless G router (via RJ45), which is plugged into my Motorola Surfboard (Docsis 1.0/2.0) cable modem (via RJ45) which is plugged to the cable outlet (via coax).

My question to you folks: Will my lag issues improve any if I upgrade to a new (Linksys) Gigabit router and a (Motorola) Docsis 3.0 cable modem? I understand that the ultimate condition is whether or not Comcast (Washington, DC) is offering Docsis 3.0 ****broadband, but I also understand that my current gear is somewhat dated. I'm looking to you folks for advice seeing as how the upgrade I just proposed isn't exactly the cheapest solution in the world.

Thanks in advance for any advice.*EXTREME LAG OVER XBL - Solutions?

Hmm, I have a similar set up with a Motorola SurfBoard Modem and a Linksys WRT54G Router with everything connected by ethernet cables. My provider is Cablevision (Optimum Online) and while my download speeds are higher on average (between 25 and 30 Mbps) by upload has been a steady 2mbps forever, and upload is what really matters when it comes to online gaming. And with all this, I don't experience lag or dropped games at all, even on Modern Warfare 2. Sure every once in a while some on will lag or the host will drop, but other than that I haven't had any problems. My advice is to start with your router, or maybe even just a different port in you router. Routers tend to last only a few years (I've gone through 3 of these things since getting Xbox Live 6 years ago). Just make sure to check return policies if that doesn't turn out to be the problem.
@RipaX21 and James161324: Thanks a bunch for your input.I'll definitely try switching to another 10/100 port on my router to see if that helps.Last night I went into my WRT54G's set-up to see if I could fine-tune any settings and I made a few tweaks here and there. I even went as far as no longer broadcasting my SSID just in case the back-and-forth pinging (minuscule that it is) was affecting bandwidth. One thing I will do tonight is update my router's firmware to see if that helps. It's also worth mentioning that when I game over XBL, I make sure to power-down every other network peripheral in my house to ensure maximum bandwidth.After no improvement, I bypassed the router altogether and plugged directly into my cable modem. After a full power cycle (both the Xbox 360 and the Cable Modem) I was up and running. While lag improved a little (e.g. I was no longer getting lagged out completely), I was still experiencing a tremendous amount of in-game lag (e.g. hopping all over the map and having little to no control over my character).Was has me particularly confused is that I've very, very rarely experienced lag when playing on XBL over the years (primarily CoD4:MW, CoD:WaW, GoW and GoW2)... moreover, MW2 was running fine in the first few days following MW2 launch.
