Bizzare (seemingly random) connection dropouts

[Ratbaggy]

Hi there, I have scoured the net for a solution but have found no specific to this time that have helped.

Currently on a TPG 1.5mbit plan

Windows XP x64 - using internal firewall (correct ports and software excepted)

On board Network Card

DSL 302G with Ethernet

Settings:

Network OK

Port foward check: OK

Global MAX Upload: 97 kB/s

Global MAX Connections 45

MAX connections per torrent: 100

Upload slots per torrent: 6

Use additional slots if required: false

MAX active torrents: 3

MAX active downloads: 2

Enable DHT: true

Peer Exchange: true

so ... now the problem...

the torrents begin to download, they do so at what seem like reasonable rates (20-40kB/s), then after a short amount of time (while I continue to surf) my internet connection seems to dropout or atleast lag, MSN drops, email can't be checked, and uTorrent rates drop to 0.0kB/s. What's even weirder is that again after a short amount of time the connection returns and I am able to function normally ... for a short amount of time, and so on until I get completely fed up and go and have a coffee.

Any clues? REALLY want to solve this one. I'm beginning to think it might be my modem/router, but I'm not even really sure how all this stuff works.

Patch TCPIP.SYS, and make sure your upload is set properly (use the Speed Guide). If it still fails, then it might be your router. If that's the case, try disabling DHT and seeing if it helps.

I have this problem too...If I enable DHT for a torrent then my router crashes within a few seconds...

If I disable it is all working fine.

I presume it is because the DHT opens a lot of new connections which the router can't take.

A lot of cheap consumer routers can't handle many UDP packets.

Yep. Whenever you have random connection dropouts my first suggestion is to drastically lower the number of simultaneous connections and disable DHT.
