New to forum. I have several computers in my house online with my cable company as ISP, via a Belkin router. No problems getting online with any of the PC's, either hardwired or by wireless connection, except one PC which happens to be via an ethernet cable. Cannot get online at all either via internet explorer or by trying to log onto AOL--I am not sure if this is any internet explorer problem, since aol uses this as their browser, or something more intrinsic to the computer. I did a Norton virus scan, ad ware scan, checked my cable connections, ran a scan on the hard drive, checked the driver for the modem and all appears to be functioning but I cannot get online (needless to say, I am posting this from another PC). The only thing that seemed to work was running a system restore to a date about 10 days earlier; it got me back on line but a day or two later I was back into the same problem all over again. The unit in question is an HP pavilion a250y running Windows Xp. Anyone have any suggestions?

I think first thing you should do is to check the network connection of the PC to the router.

Do Start->run->enter 'cmd' and hit 'OK'. Now you have the command prompt.

Enter: ping 'ip-adress of your router' and hit 'Enter'.

If you don't know the IP of your router, check the manual. Normaly it's something like 192.168.0.1
You should get 4 answers to that ping-request.
If you do so, try to ping the internet:

In the command prompt, enter: ping www.google.com

You also should get 4 answers.
If you do, then your IE is probably blocked up with spyware (as a suggestion).

1. Also at the DOS prompt, type the following command to verify that your computer's IP address, the gateway IP, DNS server IP, etc. are configured correctly.

2. If you can ping the IP of the router, but cannot ping "www.google.com", try pinging Google by its IP address instead of its URL:

ping 66.102.7.147

3. What exactly does happen when you try to surf with your browser? Please give us more detail on that, including any error essages that you receive.

When I try to surf the browser I get the usual error message that the website (whatever one I am trying to access) cannot be accessed. When I attempt to sign on to AOL (broadband) I get a message that "your computer could not get an internet conection" then sub script "there may be a network problem." Incidentally, I tried to ping google as per the first response and I did get four answers. I tried running a spyware scan and found no files infected.

Sorry, newbie that I am I posted the last response wrong so here it is again:

Also When I pinged my ip address I got four "Request timed out" messages, 4 packets sent, 0 received, 100% lost.

Don't sweat the "newbie" thing; we''l get you sorted out.

4 positive responses would be correct if your ping succeded. Was that when you pinged Google by using "www.google.com", or by pinging "66.102.7.147"?


The IP address of your own computer's network card failed? Given that you said above that you could ping Google, that doesn't make sense.

- Is your router set up to provide your computers with their IP info automatically via DCHP, or do you maunually enter the IP address, subnet mask, gateway IP, etc. in each computer's network properties?

- On the problematic machine, please run the following command from a DOS prompt and post the information that the command returns:

ipconfig /all

- On the problematic machine, do the following ping command and tell us the result:

ping 127.0.0.1

- Just for reference, what exact model of belkin router are you using?

Can you connect to anything else like a messenger program or online video game?

It must be an Internet-Explorer problem. Could be a hijacker or something similar. Did you try Spybot aswell, or eScan?

Spybot => http://www.safer-networking.org/en/index.html

eScan => http://www.mwti.net/antivirus/free_utilities.asp

By the way: seems like a good opportunity to get rid of IE and switch to a different browser:

www.mozilla.org
