Default Invalid IP address

I cannot re-establish wireless access. I have an HP Pavilion DV8125nr Media Center laptop that I have used wirelessly successfully for the last 2 years with my Linksys WRT54G2 wireless G router.I ran into some computer problems that made me have to reinstall Windows XP (the factory original disk had Symantic/Norton on it and since it was expired, I deleted it). Now I get no wireless. I get the error message "Invalid IP", and it comes back with one that starts with 169. When I try to use the "repair IP address" function, it comes back with 0.0.0.0. I saw on Windows help that if you remove Symantic/Norton protection, you have to go to a certain registry key and delete SYMTDI, then you will be fine. I found the key, but that SYMTDI wasn't there. I have tried online suggestions, everybody seems to be having this problem, but none of the solutions seem to work for anybody. I still get the error message "low or no connectivity". Any ideas? I called Comcast (my net provider), they say it is a problem with the router. I contacted Linksys, they say it is out of warranty ,they can't help me, but they don't think it's a router problem anyway. I can't believe i'm having this much trouble. Any help would be greatly appreciated.

Thanks,

Dustman

Download and run the norton removal tool here.

If you still can't get online then try uninstalling your wireless driver and reinstalling it again.

Default Thanks, johnb35

Hello, johnb35,

Thanks for the response. I downloaded and ran the Norton removal tool, still couldn't connect. I checked in device manager, I had a Broadcom 802.11b/gwlan, I tried to update the driver, it said the device was working properly and the driver in it was the best one for it. I downloaded Belarc, and it gave all of the information, the APIPA address starting with 169, which I am not sure is a valid IP address, as I had seen those starting with 169 are invalid, but I had also seen online that those were Microsoft IP addresses. It showed "Dhcp: none responded". I don't know where to go from here.

Thanks again,

Dustman

Go into network connections in control panel, right click on your wireless connection and click on properties. highlight internet protocol(tcp/ip) and then click on the properties button. make sure the that obtain ip addiress automatically and obtain dns server address automatically are checked.

Hi, again, johnb35,

Both were already checked "automatically". I did notice it offered me a place to put in an IP address manually. I have an IP address for my ethernet that looks ok, but I don't know if it will let me use that. The one that comes up for wireless is the one that starts with 169., which I think might be an invalid one.

This really baffles me.

Thanks for your help, I do appreciate it.

The 169 address is Microsofts default IP address for when there isn't one issued for your pc.
Question: Can you connect to the internet via ethernet? Hardwired. (not sure if you are currently using it
to post, hence why I asked).

Hi, again,johnb35,

Yes, I can connect with the ethernet, but I have to carry the laptop all the way to the back of the house to hook onto the router, and I use the laptop normally clear at the other end of the house near the kitchen where my work files are. So I can connect hard wired, but not with my wireless router, which I bought for this laptop.

Thanks,

Dustman

Ok, all,

When I opened properties on my wireless, both auto tabs were checked, but there was a line I could choose that would allow me to insert an IP address myself. I had one for the ethernet, so I put that in, and it said I was connected with excellent strength. I let the ethernet one find a new IP address so there would be no conflicts.

I then unplugged the ethernet cord, my wireless connection said I was connected at full strength, but when I tried to get on the net, I got that dreaded "this page could not be shown" (the same one that opens when you forget to plug your ethernet cord in).

It seems like we're getting closer, but what in the world could be hanging it up now? Man, this is aggravating!

dustman.
I know you checked already in device manager, but try this. Right click the wireless adapter
and select Uninstall. Then restart your computer and it should find the device. Try that and see if it helps.
