Intel 82578DC with Windows 7 64-bit kills wireless
« on: April 05, 2010, 04:44:14 AM »
I recently built a new computer with an Intel DP55WB motherboard which contains the 8257DC Gigabit controller.  I am running Windows 7 64-bit with the latest Intel drivers.   I have noticed that when the new computer is on the network, the wireless recycles and then completely fails.   At first, I thought the DIR-655 had died, but when I rebooted the router with the computer turned off, the wireless came back up.   I checked the router logs, and multiple wireless restarts are clearly indicated.  After about a dozen wireless restarts, the wireless turns off.   

I am running firmware 1.20 (I haven't seen any reason to upgrade until now).  Does anyone have any idea what's going on with my new computer, and do you have any suggestions?  Thank you very much for your assistance.

I had simlar problem. I was getting wireless restarts about every 5 to 7 mins. Look at some fourms post and it talked about Symantec endpoint proctection (AV) having an issue. I look at my AV logss and saw a lot of block IP6 broadcast. So (unbound) remove IP6 from my network adapter and it have resolve the issue. I have not had a wireless restart in 3 days. I thinl Win7 put IP6 on the adaptor by default. I suggest removing it and see how things work. I do not these Dlink routers able to support IP6 anyway.

Your NIC is not likely to be the culprit.
