Windows 7: Win. 7 Connectivity issues

Win. 7 Connectivity issues

K, so I'm having problems on my desktop. I'm connected to the wireless network in question on my laptop, and I'm the only one having problems in our house.

These problems were happening BEFORE I made the switch from my previous wireless card to an Encore Electronics 802.11n Wireless PCI Adapter... drivers are installed and whatnot.... It's an N router, so it should be fine.

It'll randomly be fine then randomly not be fine. Tried messing with the DNS with OpenDNS and that failed. Troubleshooting won't bring up the issue, sometimes it'll say 'DNS server isn't responding' other times it'll say 'limited or no connectivity'. Other times it shows it's fine, but it won't connect to anything.

Edit: Now it says that Windows can't communicate with the device or resource (primary DNS server).

Hi Jaws13- have you eliminated firewall/antivirus problems? What packages are you using?

One problem I see here is that your default gateway is showing two addresses, the first looks to be messed up.
Default Gateway . . . . . . . . . : fe80::222:75ff:fe5f:3c48%14 <<<<<problem here
192.168.2.1 <<<This is the only address that is supposed to be showing for your default gateway.
DHCP Server . . . . . . . . . . . : 192.168.2.1
DHCPv6 IAID . . . . . . . . . . . : 234887399
DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-13-07-6C-F9-00-1F-C6-AE-BD-3F

Usually just resetting the router will fix these sorts of problems.

I use Avast! Free version, Spybot: Search and Destroy, and from time to time PG2. I run the same on my laptop.

Tried that, didn't work. Reset through the command prompt <ipconfig/release> then <ipconfig/renew>...

Gave me the same thing. So I went into the IP protocol version 4 properties, and manually inserted the default gateway, subnet, and IP. Tried to troubleshoot, said that DHCP wasn't enabled, said it could fix it and so I told it to do so, as admin.

Went into the command prompt again to check the setting, and it still has the same problem, even after resetting the router. It connects to IM, sort of, but not anything else.

Have you tried temporarily disabling your laptops a/v and firewall?

The problem's on my desktop, and I run the same programs for AV on my laptop. Unless something messed up the AV on one machine and not the other, I don't see how the firewall could be the issue.
