High-bandwidth (?) WAN latency spikes

Hey guys,

Thanks in advance for offering your time to help people like me. My tech knowledge is probably above average (below for this site), but the problem I'm having is compounded that I don't know a whole lot about WLAN configuration.

I moved a couple of weeks ago, and Comcast informed me the only options for internet are to run 80ft of cord along my baseboards and molding (the jack is in the front of my apartment, and I want my computer setup in the bedroom - at the other end). Anyway, very ugly if you can imagine. Or switch to wireless.

I'm using Windows 7 x64. My router is a Belkin F5D7230-4 v9 (I just put in the latest firmware update... it's the 4th I believe). I have a standard (new) Belkin b/g USB wireless card.

My internet is generally OK, but when gaming (and only one game in particular do I play - League of Legends if that matters) it's just a horrible situation. My in-game latency will go from 100ms to 650ms, the entire thing will freeze and just lag horribly. It's sporadic, but it generally happens more often when things are happening in game. For example, it's more likely to happen when I'm going to fight another enemy verses just running around on the map. Things will just freeze and when it catches up I'm dead.

Comcast in their infinite wisdom told me my internet was just too slow for gaming. I knew this was a lie, but they offered to upgrade me to faster internet (6 mb) for cheaper than the 1.5 mb speed I was paying for. Can't say no to that.

Important to note, in my old apartment I had no issues whatsoever (and everything was the same. 1.5 mbps internet speed, comcast, same PC), but was hardwired in.

I'm the only person on the WLAN, and it's encrypted. I've toyed with changing broadcast channels since I assume everyone else in my building has wireless too, but after a couple tries and no improvement I gave up. Do you think putting my PC in a DMZ is worth testing? I just have no idea what the problem could be. Is my router itself just cheap?

Interesting update I just ran from this. They even say "Unable to test packet loss. Some online games may not perform optimally"

Hi Rocetmal

I'm not expert, but I've taken a few networking classes already. I have the same exact issue, with the same exact game, just with a different ISP. I get 10 megs though, and still my latency spikes up to around what you're getting (It even happens when I play some WoW, too). Does your character stop responding to mouse clicks? Does it slow down to a stop, then it seems like someone hit fast forward on the screen? I've talked to several tech reps and they all say it's nothing on my end. I've ran Netalyzr a few times, and it's showing I'm getting packet losses. I'm at a loss on what to do, so if anyone would help you out, it may help me out as well.

I've tried everything my knowledge has lead me to do; QoS, Port forwarding, reinstalling my Wifi, throttled other users in my house, etc. Nothing has worked. I read somewhere that Windows 7 has a built in feature that constantly scans for new networking, but I can't figure out if that's what is making my ms jump to 700ish every minute or so or what.
