DNS Not Working For Wireless Interface, But OK For Wire

[superman859]

I have noticed an issue these past few days that really confuses me.

I have both a wired and wireless interface on my desktop. The wired works fine. The wireless, on the other hand, does not work with DNS. I can ping remote addresses by IP, but not by domain name.

I've tried the basics - ipconfig /release, ipconfig / renew. I checked the DNS settings on the wireless router and they are correct (not to mention our laptops, using the same gateway - everything with DHCP) work on the wireless network.

I'm not sure what broke it. I first noticed this issue when I uninstalled 'DNE Update' from my machine. I believe I had to install it when I was trying to get Cisco VPN working. I never got Cisco VPN client working properly, and switched to Shrewsoft VPN client which has worked fine. I uninstalled "DNE Update" and then started noticing that DNS wasn't working. I uninstalled Shrewsoft VPN and everything was back to normal. I reinstalled Shrewsoft (but not DNE Update) and everything was working fine, for a couple of days. Then, it wasn't working again.

At this point I realized it was just the wireless that wasn't working, but wired did (wired is always connected, but it seems like if I connect to wireless network then it chooses to use wireless instead of wired).

I just tried reinstalling DNE Update, but no change.

Does anyone have any idea what the problem might be? Where should I begin to look?

If you disable the wired connection, does your wireless connection start working?

No. It's the same situation. I can ping machines and work with IP addresses, but not by using their domain name.

Try changing the preferred DNS server for your wireless setup.

1. Click "Start", type "NCPA.CPL" (without quotes) and hit Enter.
2. Right click on the wireless connection, then click "Properties".
3. Click on "Internet Protocol Version 4 (TCP/IPv4)", then click "Properties".

4. In the Internet Protocol window, change the "Preferred DNS server" to 208.67.222.222

5. Click 'OK' twice.

Also, do you have something called "Microsoft Virtual WiFi Miniport Adapter" in your network connections? If you have one but dont use it, try disabling it.
