The problem is, I will randomly lose my connection completely every few hours.The only way to immediately reconnect to the internet once the connection is lost is by repairing connection (via Network and Sharing Center), unplugging & replugging the ethernet cord back into the tower, or restarting the computer. If I do not do any of the following methods, my connection remains lost. I've posted on this forum before, and it was assumed that my internet connection problem was hardware related. Well, after bringing it into the shop twice now, they ran my computer with internet for over 48 hours and never had a problem with the connection, which proved that it was not hardware related (because with my experience, they would of at least has 2-4 disconnections during this period of time). When I called my internet provider several different times, the technicians did not see any problems on there side and claim that it is not a problem with my modem because the other computer that runs off the same connection never gets disconnected (while this one does). I've literally tried everything to fix this problem. Updating all drivers, reinstalling drivers, replacing ethernet cord, running virus scans, changing ports in the modem, and so on...nothing has helped and now, I feel lost. This problem can be extremely irritating at times...I need to find a way to fix this. Can anyone provide help? It would be greatly appreciated...

Find your network adapter in Device Manager, right click it and go to Properties. Check under the Power Management tab to see if there's a tick in the "Allow the computer to turn this device off to save power" box. Remove that tick, click Apply and OK your way out. It's hard to believe the answer could be this simple but it's worth a look.

Sorry about the relayed response! I did not expect feedback so soon. After checking the Power Management tab, the "Allow the computer to turn this device off to save power" option was checked, so I unchecked it! I'll report back my findings :)

Does the ethernet LED go out when the connection is lost?

Please show the following for when you have a connection and for when is has been lost.

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

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

If necessary use a text file and removable media to copy the results to a computer with internet access.

It just went out again, and I immediately checked the light on the modem. It remained green, and blinked every 2-3 seconds. When I checked the light on the back on my tower (where the ethernet cable is plugged in), it was green and also blinked every 2-3 seconds. In other words, the lights remained exactly the same when they were disconnected as when I was connected.

from that information you have lost connection to the router

what firewall do you have ?
make and model of PC

also post a screen shot of device manager

------------------------------------------------------------------------
{Device Manager}
Post back the results in device manager
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
windows 7
start > control panel> System and Security> Device Manager

network adaptors, click on the + > post back the devices listed there
are there any ! ? or X


post a screen shot of the device manager - network adapters

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here

I don't know if it has anything to do with the disconnects but those lease times indicate that your router or computer (I think router, but I'm not sure) is living in the past. Suggest you fix the date.

These tests are actually a bit dated (month or so). I used these on another forum post on here in the past.

Yes, but this may take some time to get all this information due to the fact that I have been unable to remain on the computer due to school. I'll post asap.

we have plenty of time here and trying to fix something from a month ago and connected to a different network will be difficult to fix remotely

i think some more detail on your setup is required
