packetloss

I have a Windows 7 64-bit machine that is losing up to 20% of IP packets on both adapters - wireless & LAN. Browser traffic appears to be affected the most, but it is happening to all protocols.

All other computers on the network are functioning fine.

If I ping from my faulty machine to any machine on the LAN (wired or wirelessly), including the router/gateway and internet sites, I get up to 20% packet loss.

If I do the following commands:

ipconfig /release
ipconfig /renew

then I sometimes get my network performance back for a matter of a few seconds to less than a couple of minutes.

Rebooting also works for a short period of time.

This problem has been occurring for a couple of months and is getting worse. The computer used to work just fine.

I updated the wireless adapter firmware the other day with no effect.

Does anyone know what is happening?
