Internet Locks Up

December 1, 2009 at 21:18:46
Specs: Windows 7
Every time I try and download a file over 750 MB, the internet access locks up. I have to unplug both the cable modem and the wireless router for it to work again.

FTP, Torrent, HTTP, you name it, large file, kills the internet.

Windows 7
DIR-655 Router
Comcast Cable (Standard modem)
Fastest internet Comcast offers.

Any ideas? Thank you!

I also just noticed, that my downloads start at about 1.8MB/second, then drop to 1MB/Sec, then quickly drop to 200kb/Sec, then locks up...

If this happens, can you ping a webserver in the internet?

Don't unplug anything, simply try this:
Click Start / Run
Type CMD and press enter.
In the command prompt type

No, I am unable to ping google. Neither from CMD, or from the router.

Maybe Comcast is reducing the traffic or disconnects on heavy downloads.
Check out, whether the router or modem has a public ip address, when your internet gets stuck.

Locked up again, and yes, according to my router, I have an IP from Comcast. But the router still wont ping Google or Hotmail.

Has it worked in the past?
If so: What has been changed since then?

Have you already checked, whether your D-Link router has installed the latest firmware?

I updated the firmware yesterday. No change.

And no, this has been an ongoing problem from the start.

I set up an SSH tunnel for uTorrent and it seems to have helped. Maybe Comcast was throttling my connection... ?!?!

Be sure, they do.
Also the most other P2P protocolls are blocked or throttled.
In that case, Comcast isn't the best choice.
