Re: Suspected modem at fault?
 

http://www.cableforum.co.uk/board/12...rting-one.html < My issues are posted here. So far it's coming onto nearly a month with connection problems.

Problem:
Random cutoffs with connection when a p2p program is in use. By random i mean, I can be using the p2p for a while and it drops, and then connects, or drops and doesn't allow any connections of the net till it's closed or it can drop as soon as I open a p2p up. I can get it briefly working by unplugging and plugging the modem power back in, but there's no guarantee that it'll won't drop shortly after.

Router is not the cause, as it happens even when directly connected via modem.

Setup is a router (wireless (1 user) / wired (3 users) ) connected to the cable modem.
When it doesn't load any pages, the icon in the system tray seems to indicate most of the time it's uploading but no lights for the download.

It could be a virgin media issue but I'm not so sure as more people should have reported it if it were the case, so I think it's an issue mostly on my side.

The p2p I'm using I doubt is at fault and even if it were i don't think it could cause net problems for everyone else on the network. At most the only issue with a p2p i've had on the network is if i don't control the upload and it slows down browsing for everyone, but even then browsing is still possible.

The only time i've not had any issues (tested over a day) is when it's just browsing/emailing and no p2p involved.

I've tested out a lot of different conditions to test the connection on, and I think a new modem might help solve it.

Re: Net goes down when starting one P2P but..
 

I've merged the threads since clearly this remains the same problem you haven't resolved.

What make & model is your current router? Some are known not to handle P2P stuff particularly well since they get overwhelmed by tracking the number of connections being maintained. Early Linksys WRT54G series were prone to that. Using third party firmware and making some adjustments to the standard config can solve that.

Realistically, maximum connections of around 60-100 should be more than sufficient. your post #4 seems to show an extraordinary number.

Do you get these problems with a connection direct between the computer and modem - no router?

Re: Suspected modem at fault?
 

Fraid so. Oh and model and make is Draytek vigor 2100. I had a WRT54G Linksys, but it got bogged down with connections and required a reset too often, so made a switch to Draytek and i've not had the same issue.

Currently trying out utorrent on another computer, too see if it makes any difference. I'll report my findings later on.
