I have 2 laptops and a PC connected to my router to access the internet. The laptops are wireless and PC cable. All three connected without trouble to the internet.

I have upgraded one Laptop from XP SP2 to XP3. Since then I cannot access the internet. I do connect to the router. If I look at the wireless network properties it shows as connected, good signal strength but there is now a picture of a lock. How do I unlock this so I can connect to the internet again.

Please help
 
Open command prompt, type "IPCONFIG", hit enter and paste the output here.
 
Done but it displays my IP add, subnetmask and Default gateway add.

Not sure it is a good idea to paste that here

That's because you typed it in "run". You have to type it in a command prompt for it to stay open.

Those are private addresses that are useless to anybody out there.

If your IP's fall in the following ranges then you are safe to post here,
10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255

If there are things like SSIDs, passwords etc then you can edit that out.
 
Look, pretty simple. IPConfig to confirm your NIC actually gets an IP assigned, assuming you do not have a static IP configured. Either way, it'll give us some required info.
Secondly, ping your router from the misbehaving machine to check whether you actually have comms.
If this works, then pretty much the only reason your internet wouldn't work is gateway settings which we can confirm with the IP info requested in the first place.
 
I believe this is a XP SP3 issue with some routers.

That gateway looks wrong. Should 10.0.0.1 if I'm not mistaken. Bit tired to diagnose further now.
 
The Win7 laptop that works correctly reads

Make sure the cable is properly seated at both ends. next check the adapter settings, play around with speed/duplex, powersave etc sttings.

He is connecting via wifi, so there is no network cable.

Log into the router and verify that the router isn't blocking internet access for that specific IP address, also check if that machine is listed under the list of clients that are connected to the DHCP list. There shouldn't be anything there, but also verify that there isn't a proxy setting somehow setup on that laptop.

@Mesugga: The gateway can be anything you want, as long as it is the correct address to the router (in this case).
 
I have set up an dial up connection, so the wireless connects to the modem and I use the dial up with my username and password to connect. Bit cumbersome but at least it works till a proper fix can be found.

Thanks all for your efforts
 
What ADSL router are you using? There is a known issue that prevents XP SP3 machines from getting DNS settings from the router via DHCP with some ADSL modems/routers?

I am well aware of that. It's just unlikely in my opinion that someone asking simple questions would change from the default IP settings. Of course, you are correct in saying that it should be the same as the device providing the Internet connection's IP.

No problem, was just preventing a potential panic attack :D. Someone asking simple questions might go into overdrive if some tiny detail doesn't seem right and try "rectify" it with gusto :p.

@OP: Assuming you have checked the entries inside the router, type "ipconfig /release" and then "ipconfig /renew" to flush the address and force it to get a new address. Failing that, set a static IP on the XP machine within the IP pool of the router and check for connection out. Lastly, are your wifi drivers up to date? Plug your XP machine into the router via a network cable and check if you can gain access through there to determine if it is wifi specific problem or if it is a machine/operating system problem.

Tekom Mega 105WR. Yes I believe that is one of the problematic ones. Could not find a solution to fix it yet.
 
I found that sometimes when I have been travelling and I have a number of different wifi points listed on my laptop, I have problems connecting to another spot. I just tend to go into my wireless networks under wireless network connection properties and delete all my preferred networks out and then try and reconnect to the new network.

I usually find it helps me. I am also using Windows XP service pack 3
