Your line speed:
568.2 K bytes/sec
I'm guessing that's a pretty good line speed, yet everytime I play on Xbox LIVE, I get god awful lag, and bring the entire servers ping down (and not down in a good way like ping is supposed to be)
I ran the Xbox's network diagnostic, and my packet loss is something like 12/25 packets, which is close to 50%...
I have called my ISP, and had them run a new line for a connection into my room, and moved the modem up there, that way I am no longer connected by a 75 foot cable around the house (What Xbox LIVE suggested I do) No luck. I'm playing via a Linksys router, but even if I connect directly to the modem it still doesn't help. My ISP isn't much help, they just tell me to call Xbox's support, who in turn tells me to call my ISP.
Any idea how I can fix this, or what's causing it?
