Default gateway becomes unavailable after few mins of using Torrents

Hi,

I have noticed similar threads and in a mad desperate attempt to fix the issue tried the suggested solutions but still got problem.

Gaming, surfing, normal downloading is great. However as soon as I open, utorrent,BitCommet downloads will work perfectly for about 5 minutes then the DEFAULY GATEWAY becomes unavailable.

Some things I've done so far:

• Removed IPv6
• Manually added Gateway, Subnet mask & IP address
  IP-192.168.2.2 Default Gateway - 192.168.2.1
  Subnet 255.255.255.0
• Removed Link layer tapology
• Checked firewall (application is allowed with TCP UDP)

Problem occurs weather ip etc is set to automatic or manually added.

What fixes it?

• Disconet from network, re-connect
• windows troubleshootfix (where the problem is shown as default gateway was unavailable)
• Sometims a restart of the router is needed.

Hardware used:

Belkin N USB
Belkin N1 Vision Router.

Any suggestions?

Many thanks in advance,

Is this a new problem? does your ISP have a TOC that forbids torrents? does it do the same thing when you boot in safe mode?

I previously had the SAEGEM sky router with no problems, however I did use BitLord then. The sky modem/router was not achieving optimal speeds, peaking at 11mb, where-as the belkin router achieves 16-19mb.

Is it a new problem, yes. TOC - I'd guesse at a no as bitlord worked with old router.
It maybe worth while reverting back to old router to test for newly implemented technologies. However, while i have been browsing, and the torrent client running, connection has been maintained. I shall test this a little long to measure its success.But on the whole, every annoying, very odd

I had the same issues here:
Internet browsing works great except Torrent downloading. In the same LAN, XP box works with no problems at all.

I tried two different routers, no luck;
I connected PC directly to ISP modem, no luck.

Since there is no supported Win 7 driver for my NiC, I added a wireless adapter which has Win 7 driver. From then on, all works great.

Hope it helps.

typically this problem occurs because you're saturating your UPLOAD bandwidth with data that you're sending to torrent peers.

when you are DOWNLOADING information, you're still UPLOADING ACKnowledgement packets. these are very small, but if they get lost or if they have to wait, it creates latency and timeouts.

when you're "Gaming, surfing, normal downloading", you're not saturating your upload pipe. when you're using P2P, you're UPLOADING files and your pipe ends ups queuing EVERYTHING which equates to latency.

typically, an ISP will give you a massive download pipe but a very small upload pipe.

SOLUTION: find out what your upload pipe is by doing a bandwidth test (preferably using your ISP tester not something outside your ISP's network) and limit your P2P upload rate to about half (or perhaps 75%) of your max upload rate.

by limiting the upload rate, you ensure there's ALWAYS room for outgoing ACKs, SYN and other handshake packets.
