OK, so I had a client call me yesterday about is Dell laptop which connects to the wireless but cannot not surf the Web. Its windows XP SP3. This was a little UN nerving for me since i've never had to leave a clients house without fixing the problem. I worked on this for about 2 hours with him. He was a real nice guy so I didn't mind. I told him to get a usb wireless network adapter and see if that made a difference. I talked to him today and he's having the same problem. I'll be heading to his office in the morning to see if I can do anything else. Anyone have any idea what else I could try?

Thanks for any help
 
A little more information would be helpful. When you say you're connected to the wireless, are you actually getting an IP address? Can you ping the router? Can you surf the web is you use a ethernet cable?

What have you done to try to diagnose the issue so far?

If you have any third party app that is controlling the wireless, you might try letting windows control the wireless and see if it's a third party issue?
 
1. Did you check to see the internet was working directly with a laptop.

2. Were you able to connect to the network

3. Does he or did he have Norton antivirus? and try to remove it without the removal tool ?
 
I can ping google without any problems and the ip address, dns, submask, etc are all fine ... I'm using windows to control the wireless. I can get the wireless connected with the nic, but cant surf the web. When you open IE or FF it just says that the web page can't be displayed. You can't surf the internet via the ethernet cable either. I've tried the winsock fix patch, i've tried repairing the connection, tried a new usb nic card ... i've uninstalled the device and reinstalled it. Installed new drivers for nic, etc ... Really not much more you can do at this point.

1. Doesnt work either
2. I can connect to the network but cannt not surf the web.
3. No Norton.
 
Check for a proxy. In IE tools/internet options/connections/lan settings. Since you can ping try entering an ip address in the browser and get out to verify its not a DNS issue.

Otherwise from what you said so far it hasn't even been verified that its not the router being flaky. See if another machine can get out connected wirelessly to their router. What about resetting their router/modem?

Are any other computers working properly on this network or is the laptop the only machine he has?
 
I'm assuming you scanned for malware and found no issues? Ran hijackthis and nothing suspicious on the log?
 
Yes, no spyware/virus. As much as I hate to say this... but i'm thinking maybe a reload might be in order. But i'd hate to do that and the problem still there after the reload. I'm lost and not really sure what else to do.
 
Copy Dial-A-Fix from flash drive to desktop, run app, have all options checked (except IE if it is newer IE and date time isn't really needed) and see if that helps...7 out of 10 times that resolves the problem. Since you mention that Norton is not there, find out if it ever was or what other security/firewall/av was, run the removal tool for Norton or whatever app it was and you pretty much cover the other 3 of 10 times....

I will give it a try. Thanks to everyone that responded!!
 
Also try this. Open Notepad, copy paste, save as 'Reset LAC.bat'

Code: 
ECHO Off

REM This is actually a Batch file but 
REM there was no catagory for this.

REM This batch file resets the network 
REM for the local computer, then restarts
REM the Network Services.  It also creates 
REM a file with the new IP Address.

ipconfig.exe /release
net.exe stop "dhcp client"
net.exe stop "dns client"
net.exe stop "network connections"
net.exe start "dhcp client"
net.exe start "dns client"
net.exe start "network connections"
ipconfig.exe /flushdns
ipconfig.exe /renew
IPConfig.exe /all >> C:\IP_Info%date:~-4,4%-%date:~4,2%-%date:~-7,2%.txt
Notepad.exe C:\IP_Info%date:~-4,4%-%date:~4,2%-%date:~-7,2%.txt
 
Broken (or expired, in one case) installations of antivirus, antispyware, and firewall software have been the most common source of this problem in my experience. Also, you haven't mentioned whether or not you've tried browsing in Safe Mode with Networking. If you're able to do so successfully, the next step should be to check Startup and Services for anything that should or shouldn't be there.
 
Wished to add that you should check the adapter properties and see that Client for MS, TCP/IP and such is selected and that the properties for the TCP/IP are not manually set or in the advanced or submenus that filtering is not enabled, this happens alot as of late.

These prob you know but might help.
 
I'm going to point out something that should never be a problem but I've seen it more than once...

Create an exception for port 80 in the Windows Firewall and any other firewall that may be installed. Also open port 443 for HTTPS.
