Dell laptop Unable to get valid Ip address on network

February 3, 2012 at 01:28:47
Specs: Win XP
I have a Latitude D810. recently unable to get connection on wireless or wired. Lights are on on port plug. I can see the network, when I run troubleshooter on the Proset/Wireless Wifi Connection utility It says the wireless adaptor failed to get IP address and could be due to authentication failure with the network, incorrect wireless security passwords or because of DHCP server malfunction. I did the passwords, checked the router, all is ok there. My new computer works fine on this wireless network as well as my wired desktop. I suspect this happened as a result of a security change that windows XP or whatever security soft ware that's in there did, but cannot figure out how to undo or reset this. Just prior to this happening, I kept getting a page hijack about every 20 minutes or so, maybe a virus I don't know.
I had to have a laptop for school, so I bought a new one, but would like to fix this issue on the old one. Also being connected would help alot with transferring old files to new computer. Any help would be appreciated. Thanks in advance.

Try using System Restore, choose a date that's earlier than when the problem was first noticed.

Your first step is to determine the extent of the issue.
You connect WIRED to the router. Do you get a ip?

BTW a page hijack is not something you ignore. Its a sign you have been compromized.

No IP with wired connection either.
I'm not sure that hijack was the correct term, What it did was everytime a new page loaded. I'd get an additional page that overlayed the one I wanted. the unwanted page was: News Daily 7-something about work at home...I could close that page and move on to my original intention. sometimes the page would load even if I wasn't doing anything.
Now what I know is that it was Microsoft Security Essentials that stopped Trojan Dropper:Win 32/Sirefef.B according to the essentials history. I know the wireless stopped working at about the same time as this says it removed it.

What you describe is malware.

My experience with MSE is that its garbage. It only finds the obvious stuff. Get Avast and malwarebytes.

You can try this

Doing the system restore to before the malware happened is a good suggestion.

At the onset of the problem with the unwanted pages, I ran Malwarebytes program on the computer. It did not find anything. And would malware cause my network card to stop working? or do you think the MSE did that?

OK I was waiting for further instruction before doing restore, so I'll go ahead and do that now, then install Norton 360 that i got when i bought my new computer.

I would hold off on the norton 360. It has known issues and may just muddy the water.

Yes malware can and will stop networking.

Never ever install Norton 360 it can cause serious issues......

Googling is quicker than waiting for an answer....

ok, tried the system restore twice, both times, it said it didn't complete and that there was no difference in the computer now and the previous dates that I picked. I know the computer was doing fine on both of these dates a month apart. .... so now what? and I didn't install norton.

I hate s--- that don't work right!

My method is to replace the hard drive with an empty one and install the operating system and programs. After it is working correctly, then restore the data files.

that is probably the quickest solution Wizard Fred. It's about a 6 or 7 year old lap top, that I bought off the internet about 5 years ago. I've gotten my money's worth out of it for sure. I don't have the Cd's for windows xp or for some of the other stuff that is on it, so.. that's not really an option for me. I'll keep digging, I think I know what is wrong with it, I may have to ask how to do what I think I need to do if I can't find the answers.
