This post is just to get some information on how to go about confronting an ISP that filters Xbox Live packets. I know that Xbox Live uses custom packets that could be easily filtered, and I am pretty sure my area has started slowing them down in the past month or two, even though QoS should be pushing them first instead as Microsoft intended.

I'm using a cable modem in Orlando with BrightHouse (I believe the service goes under a couple of names in this area, possibly including Earthlink, but it all comes from the same source), this problem is somewhere around month old, coinciding with the release of XNA 2.0 and the beta, though admittedly there is absolutely no way to know if this is coincidence. It has however affected other users as well and has been documented:

Demo downloads which used to go quite fast now take literally entire days to complete. Regular Internet access is fine. I can't even play halo 3 anymore, which is quite frustrating, not to mention every other 360 game online.

I am quite sure Microsoft would take interest in this, at the very least it should be looked into (knowing that the ISP will most likely initially deny such claims, and a technician or customer service rep most likely wouldn't have been informed). Customers have had very little luck, it's the sort of thing that would most likely require direct attention from Microsoft to get any results.

Thanks.

Live packets from XNA are no different to live packets from the 360 -at least as far as your ISP is concerned so I think this is not the likely reason.

ALso since this is the XNA community forum ou are not going to get hold of any live folk here. If you have not already done it thenI would report it to tech support and also on the www.xbox.com forums where it will get to the right people much quicker than here.

I too live in orlando ... I'd call brighthouse and check to see what plan you're signed up for.  What happened to me is that we signed up for the high speed internet (cable modem) ... and then a few months back things slowed waaaaay down.  turns out, we had been eligible to get the highest speed plan, for the lowest speed's price.  they either didn't tell us about it, or we didn't notice when we signed up, but it was a limited time offer.  So when internet all of a sudden started to go really slow, it was when they switched me to the crappy plan.

This isn't normal, I can't even aim against enemies in Halo 3 anymore, I went from skill 37 in Lone Wolves to being unable to win a single game for two weeks, and downloads take days. I have a very good connection otherwise, Live is just extremely crippled.

Have you tried any of the things we have suggested? Call your ISP, call Xbox live, post in www.xbox.com

Unless you have some hard evidence that this is XNA GS related (nobody else is reporting it) then this is the wrong place for the post.
