Alright , I have an issue here !

I recently installed Windows Vista Ultimate 64 Bit.

Problem is -
Whenever I download stuff through torrent irrespective of which torrent client I am using , after a while of downloading my pc gets very slow (kind of hangs and I can only press the restart button on the cabinet) and i lose connection to the network (steam gets offline , msn / yahoo disconnects) and the network monitor at the bottom corner show a yellow exclamation mark saying - "Limited Connectivity / No Connectivity" .
I'm not able to download.

Even previously when i was in 32 Bit vista , similar problem was there.

Please help me out , not able to download.

System specs -

Q6600
XFX 780i SLI
4GB DDR2
9800GT 512MB OC'ed
Airtel Broadband 512Kbps (Beetel Wi-fi Router)

~ Vinay

Try this : Windows Vista tcpip.sys Connection Limit Patch for Event ID 4226 My Digital Life

That has nothing to do with the system slow down. @OP, does it happen even when you're not downloading torrents? Scanned for malware etc.? Checked windows event logs for errors/ warnings?

Strange that you report the same problem & we share common things
x64 Vista
airtel connection 512kbps
4gb Ram

Complained to airtel & over 2 days of R&D with various settings/changing lan cable/changing the modem, it was found that the power adaptor was giving higher power after a while & causing that to hang thus giving "limited connectivity". Yesterday evening it was changed & last 12 hrs I am running smooth.

Neither airtel could think nor I could think that this could be the problem.
So Try this it might be the case & may solve the problem.

^^ Wow lucky me , i'll give that a try directly.
Thanks a bunch!

Doesn't seem to happen then.
Plus as i told you , it used to happen when my system was 32bit and now it's a completely different 64bit fresh install , so maybe the above stated thing might be the problem? I've called up airtel they are sending someone asap.
I tried changing my torrent client from Vuze to BitTorrent , made no difference what so ever.

PS - @ Ranjan , what am I supposed to do ? Get the power adaptor changed or is there a way which allows it to give limited power to the router?

I'd say look into your Windows logs (event viewer) to nail down what's actually causing the slowdown. The TCP fix is "supposed" to speed up your torrent downloads, not maintain your connection. It might be something as simple as faulty drivers for your LAN card. Check logs and post any warnings/ errors.

Edit: Just noticed, it happened even when u where on 32bit. If so, try using a discrete LAN card. Your onboard might be the problem here if it's not a modem problem as mentioned by Ranjan.

^^ Well what i'll do is start downloading through the torrent client again and explain what exactly happens step by step.

Just something I Noticed (If it has something to do with my problem , since the problem starts only when i start downloading through torrent client and yes any torrent client. Tried both Vuze and BitTorrent 6.0 , a month back vuze gave no problem , now both vuze and BitTorrent gives problem so there's nothing wrong with the torrent client as per me)

Some Images -




Suddenly speed's start dropping and then the error is showed in the next few images (down the page)
Following that pop-up (shown in the image above) I get this error on the uTorrent Port Checker -

Welcome to the µTorrent Port Checker.
A test will be performed on your computer to check if the specified port is opened.

Checking port 26620 on 122.162.133.155...

Error! Port 26620 does not appear to be open.

Please see PortForward.com - Free Help Setting up Your Router or Firewall for more information about how to map a port.

Please make absolutely sure that PeerGuardian2 or Protowall is allowing utorrent.com (72.20.34.145) in either of those programs. Those of you using ipfilter.dat should make sure the list does not include the website's IP. After making sure of this, re-run this test by refreshing the page (F5).

Now the problem steps in , The PC does not hang but it goes DAMN SLOW !! (Cursor takes ages to move etc.) Speeds drop, I lose connection to the internet , yahoo messenger , msn messenger , steam , browsing (firefox) and just everything!






Any help here?



PS - I guess problem with port forwarding?

^^ Please remove or blur out the first pic before someone catches you red handed with your downloading spree.
It seems your on board lan card is at fault. Borrow a discrete one from a friend and check if it makes any difference.

Edited !

PS - The problem might have started after I installed Bit Defender Total Security on my PC ! (But i have the same anti-virus on my laptop with Windows XP SP3 32Bit , works without any problem)

^^ Tried using uTorrent as well , problem persists.

Your problems are exactly the same which i was facing & airtel guy even told me that my onboard lan card seems to be faulty, so I switched to another port (I have 2 lan ports) but the problem remained.

I then connected the laptop & that too had the same issues after a while, so we concluded that problem could be the modem/lan cable/.............................last thing on our mind was power cable for the modem.

I don't use much torrent clients but I was having the same problems in general browsing & downloading files. Sudden drop of connection without any errors.

Try changing the power adapter, I am not sure if it solves the problem in ur case but last 24hrs I am running smooth & got back full speed of airtel.connection.

----------------
Solutions to the problem sometimes does not lie where we think them to be, its specially true with computers & girlfriend/s.
They both like you to keep guessing the solutions.

That seems to be a LAN card or modem problem. I just saw the same slowness on a PC today when the router was acting up with it's DHCP.

Have you tried to update your LAN card drivers? Give it a shot if you have not done that.
