No wireless/wired net access

June 23, 2010 at 09:02:56
Specs: Windows XP
I've been using wireless internet for months with my new computer which has Windows 7 64-bit. Today I disabled the wireless security for a bit, then tried to enable it, now I can't connect to anything. The problems are: 'The DNS server isn't responding' and 'Local Area Connection doesn't have a valid IP config'. My wireless icon keeps switching between a yellow exclamation point icon and a circular blue loading icon. It says it's connected but I cannot browse the net, I can access my router information though. My router/modem are definitely on and connected. I've done many power cycles on those and my computer. My modem is Comcast and my router is a Netgear WPN824 V2. The router has the most recent firmware.

Here is my ipconfig data:

Please help, I need the internet on my computer to be able to do work. Thanks in advance.

post the results of an ipconfig /all instead.

does the routers wan config look correct as in having an assigned ip address from comcast?
Can you ping/access a web page from the router [via a test button or command line in the router]?

I always used the options 'get dynamically from ISP' for IP address, DNS address, and 'use default' for MAC address.

There's no way to access or ping a web page from the router settings.

I figured out a bit more about my problem. It almost has to be a problem stemming from a large electrical storm that happened yesterday, which I'm certain damaged my previous router, which I've since replaced with a new WNR2000. The old router and surge protector is gone, but I still cannot connect via wired or wireless.

Your help and replies are much appreciated.

Hai vector03,

Thank you for posting your problem.
Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::7138:eac7:eba3:d54%27
IPv4 Address. . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

This is the data from your ipconfig.
IF Connection-specific DNS Suffix is blank, then I would suggest you to cross check if the IP is assigned manually.
Obtain IP Address automatically should be selected.
I appreciate that you have tried the step many a times, but give it one more shot. Let me know the updates !!

Regards,
netfreak10
