Wireless connection stopped working in W7, please help?

When I bought my PC almost a year ago and installed Windows 7, the wireless connection worked fine. However, the connection began dropping occasionally, so I plugged the cable back into the router. Now, whenever I unplug it, the connection cuts off completely. I update and scan regularly. When I contacted my ISP, they ran a diagnostic and said it was a failed media problem and could not help me any further. A `Media' problem provides no clue to what this might be. I would be very grateful if someone could please help me resolve this problem?

The only info I can find about my system is that it is ASUS P8H61-MX Series or ASUSTek. My router is: Technicolor Gateway TG582n. Below is the additional information you requested. I hope this helps?

Rightclick on the wireless icon in bottom right system tray to Troubleshoot Problems. Specify the wireless adapter. What does it find?

Enable Automatically deliver drivers via Windows Update (Step 3)
then Check for Updates, install all Important and Optional Updates, with reboots, until no more are offered. This assure you have the latest driver and are fully patched.

Make sure the wireless switch is on at all times.

I would also flush the DNS cache to see if it solves your networking problem:

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

If this doesn't help then look more closely at the logs shown in Troubleshooting Steps for Windows 7, for networking related errors logged at startup, google the exact text and identifying number of these errors or post back a screenshot of them, to research how others solved them.
