Hi, I have an Acer Netbook that could wirelessly access the Internet through the home cable modem router, but the desktop pc, fitted with a wireless USB adapter and sitting not two feet from it, has a "Limited or No connectivity notice slapped on the Network Access icon. The signal status indicates "Excellent." Both have Win XP SP3 installed. I've tried the Winsock refresh suggested fix (both with Winsockfix.exe and the netsh DOS command), but still no connection had been established.

The following are results of an ipconfig ping:

Two things:

1. The ipconfig result is displaying a local-link IP address (169.254.20.25). Basically, your computer has DHCP enabled, but is unable to connect to a DHCP server (typically your router) for a "real" IP address.

2. The ipconfig result doesn't show the default gateway IP (your router). You should be able to see the default gateway IP address (gateway being the outlet to the Internet). If you can't ping your default gateway (your router), you won't be able to hit the Internet. Does that make sense?

On your desktop PC, do the following:

1. Click Start -> Control Panel -> Network and Internet Connections
2. Right-click "Wireless Network Connection 3", select Properties.
3. In the Networking tab, look for Internet Protocol (TCP/IP), then select Properties.
4. Be sure "Obtain an IP address automatically" and "Obtain DNS server address automatically" are selected.

What type of a router is it? I'm looking for the brand and model. For some reason, your desktop isn't connecting to the router, and we need to figure out why

Can you also post the results of an "ipconfig /all" from your laptop?

Thanks for replying so fast Double_D_Edd Lemme go check the router at my sister's house (we live in a multi-split building) for the exact specs. Bad news on the netbook though, my brother in law borrowed it for his thesis project, and won't be home till later. Great explanation on the ipconfig results too, thanks!

I'll get back to you as soon as I can...

You're very welcome

I took your lead and focused on the router as the possible culprit, and apparently a hard reset was all that was needed (poking a small hole behind the router with a bent paper clip). Thank you very much! Without your input Double_D_Edd, I'm sure I would have tore off my hair while screaming for Bill Gates' head. My faith in humanity has been restored Thanks man.

Hahaha, you're very welcome! I'm glad everything's working now
