Hello all

Well for the past few months ive been forced to use my usb connection to my cable modem and well my lag while games and just general use sucks.

http://www.pchell.com/support/limitedconnectivity.shtml

Everything listed on the link above I have tried so far with no resolve.

When im trying to use my ethernet connection i get the limited or no connectivity error but when connected via usb it works fine its just slower. I have swapped modems 3 times so i rolled that out and it also works fine via ethernet on my laptop.

On my desktop it just kinda died out slowly so i was thinking that my ethernet port fried(on MoBo) So i installed a ethernet adapter in a pci slot but i still have the same results. All drivers and everything are up to date.

Just so we are clear can someone list the 100% proper/best way to power cycle a modem. To make im just not doing that right ive read that fixes alot of problems. Any help is appreciated, thank you.

Any other info that might be needed i can list im just baffled on this one. Thanks Again

Try this.


  • Turn off everything, the modem and computer.
  • Connect the modem to the computer using the Ethernet cable.
  • REMOVE the USB connection to the modem.
  • Turn on the modem, wait for a steady connect light.
  • Boot the computer.
When the computer is completely booted, let's see this.

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

This problem has plagued me in my tech support service and until recently, the normal fixes have resolved the issue. The link at the top of the post to the PC Hell post has some great info and what has fixed the connectivity on a brand new Dell Vostro desktop and another PC recently is changing the network connection speed to 10mbps. As stated in the post about XP2 and connection issues:
Many times setting the network card to 10Mbps/Full Duplex will solve this issue. To do this, open Control Panel, System, Device Manager. Go to the properties of the Network card, click on the Advanced tab and find the Link Speed and Duplex section. Change it from Auto Detect to 10Mbps/Full Duplex.
If you're reading this post and have this issue, try it.
Cheers:wave:
