I'm guessing the 546 router is wireless capable and that you setup a wireless network and that your netbook is attempting to connect to the wireless network..................

Open a command prompt window on both your PC and your netbook and type the following command:

ipconfig /all

Compare the TCP/IP settings on both devices. The only thing that should be different is the actual IP address. The DNS, Subnet Mask, and Default Gateway IP's should all match. If any of them do not, then that's your issue.

Check and report back with your findings.

You may want to verify that your netbook is obtaining its IP address automatically(using DHCP) from the router. DHCP automatically assigns your computer an IP address, subnet mask, DNS addresses, and default gateway address.
To verify DHCP setting on your netbook (assuming you are using Windows):
1. Open your network connections list
In Vista open control panel (classic view) and click on the Network and Sharing Center icon. From there click on Manage Network Connections in the left window pane.
2. Right click on that Local area connection that is your network card and select properties (make sure the connection is enabled)
3. In the box labeled "This connection uses the following items" click on Internet Protocol Version 4 to highlight it, then select the properties button
4. Make sure the option box for obtain an IP address automatically is selected, as well as obtain DNS server address automatically.

Hope this helps!

When you run ipconfig /all does it return an IP address value of 169.x.x.x? If so, your computer is unable to find a DHCP server (your router) and you may have to change some configurations in the router. Before making changes on your router ensure that your network card is working properly by opening a command prompt and typing ping 127.0.0.1. If this no packets return then your network card is the issue.

If you have an IP address similar to 192.168.x.x or other private IP address you may want to see if you can ping your other computer. Run ipconfig /all on your working computer and locate the IP address. On your netbook, open a command prompt and type ping x.x.x.x substitute the IP address of your working computer for the x's.

Please post your results

You didn't say if the DNS and Default Gateway IP's on the netbook were identical to the ones on the working computer. Are they?

IP address of net book is 192.168.1.64
IP adress of PC is 94.171.77.xxx
Pinging will not accept the change

Before making changes on your router ensure that your network card is working properly by opening a command prompt and typing ping 127.0.0.1. If this no packets return then your network card is the issue.:-
4 packets sent and 4 returned


Thanks, Phil

Ok, your PC IP is a routable IP address. You'll noticed I changed the last octet of it to x's. That's for your protection. One does not want to publish their external IP address.

Having said that, this tells me your PC is connected directly to the internet. Or at least, that's how it looks. Typical setup with a SOHO Router is as follows:

Internet >> SOHO Router >> clients

I'm not sure how you have yours hooked up but this is how it should look with your internet plugged into the WAN port of your router and any/all clients in the LAN ports.

The first thing you need to do is ensure you have it hooked up as I said. Your ISP will provide you with an external IP address either automatically (using DHCP service) or manually (statically assigned) by giving you your TCP/IP settings.

If you have static IP from your ISP you would enter those settings in the WAN side. If automatic, ensure your WAN port is set to DHCP.

Once you have your router connected correctly to your internet connection, then your clients should all work properly if you set them to DHCP and plug them into LAN ports on your router.

Thanks for all your advice. I have been in touch with the supplier and find it is the wrong unit and I am trying to change it.
Nevertheless your advice has been superb and I have learned something.

it's always a pleasure to help out. Oh, thanks for getting back to us. Most folks don't bother and it's always nice to know what did, or didn't work.

Once you get your hardware straightened out if you have any questions...........
