network between 2 computers doesn't work eith

December 5, 2010 at 17:31:57
Specs: Windows XP, 1 GB
I used to have a network between my desktop and laptop, first via ethernet, then when I got DSL and a modem router, via wifi. Then I went to Europe with the laptop, used an internet stick for wifi and put on some other programs.

When I got home, the network no longer worked. I've tried many fixes, registry cleaners, removing the internet stick program and every program I installed when I was away.

The Westell router that I call up on the desktop sees the laptop. The laptop gets on the internet via wifi from the router (which is connected by ethernet cable to my desktop. I tried running Network Magic. No magic! What could possibly be wrong?

I tried to reinstall windows on the laptop (not a fresh install), but it didn't work because there was one corrupted file. Is that a clue? I tried winsockxfix.

I thought the problem was the wifi modem. So I used an ethernet cable. The ethernet cable doesn't let me see the other computer. It registers "no connection."

Any advice besides a total fresh install of Windows on the laptop?

Does your laptop have the same workgroup name as your desktop?

When you're connected via wifi, open a command prompt window on the laptop (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:

ipconfig /all

Now do the same on the desktop. The only thing that should be different is the actual IP address of the devices. The subnet mask, default gateway and DNS IP's should all be the same. If they're not, post the output of both in a response here so we can have a look.

Thanks for helping!

Well, your TCP/IP settings seem ok. I'm thinking there will be communication between clients if you tried pinging each from the other.

I suspect your issue is software.

As to what software is causing this, it's going to be very hard to diagnose/fix over the forum. My advice would be to take it in to a reputable shop and have them look it over and fix it.

So are you saying that I installed some software (in Europe) that blocked the network? I uninstalled all the software I had installed, but that didn't have an impact.

I will try the pinging.

Do you think a fresh install of windows and reinstall of all my programs is the answer?

I'm going to try to set up a network with a friend's netbook and my desktop. Either thru wifi or the ethernet crossover cable. If that works, I know the problem is the laptop.

Can you please remove the identifying information about my computers from the previous post? 3 before this one.
Thanks. Lucy

I looked over the previous posts and there's really nothing there that identifies your computer. The TCP/IP settings are all from a private Class C network which is non-routable and is pretty much the same TCP/IP settings all SOHO Router's use so those can't indentify you either.

So are you saying that I installed some software (in Europe) that blocked the network?

That's possible, but since you state you removed any/all software you installed in Europe it seems to me to be more likely your TCP/IP stack or some of the files related to the interface itself are the problem.

Definitely try pinging. If they can ping each other and get proper responses then they should be able to connect since that's proof positive they are communicating over the network.
