Hi

There are a few things you can check.. an Internet checklist if you will:

1. Are you getting assigned an IP address from the ISP RAS servers. You can verify this by opening a DOS (cmd) window on your PC and using the command 'ipconfig /all'

2. If you are getting an IP address, try and spot from the ipconfig command sbove whether you are being assigned any DNS server addresses. If you aren't, this is probably why web browsing doesn't work.

3. If you do see DNS server(s) listed, try pinging (ping x.x.x.x) and tracerouting (tracert x.x.x.x) one of the addresses from your DOS window where x.x.x.x is the address of the DNS server. There is no guarantee ping or traceroute will actually happen succesfully as the ISP could well be firewalling the DNS server.

The important thing here is to try and prove you can 'get past' your modem and into the ISP network. The first hop in the traceroute will always be your PC. If you see any successful hops after the first one that's a bonus as it shows you have a good connection to your ISP but something in the ISP network may be preventing you access to the Internet (again perhaps a firewall).

4. Armed with a DNS server IP address, do an DNS lookup (nslookup) from the DOS window. When you type nslookup, it should return the IP address of the primary DNS server. Try entering a few common URL's (e.g. www. cisco.com) to see if this server is correctly resolving the names to IP addresses.

If it isn't, try an nslookup against any secondary DNS server IP address that may have been listed in ipconfig /all output. See if this returns IP addresses for well-known URL's.

Hopefulyl depending on the success/failure of any of the above, it should give you an idea what you need to do to resolve the issue.

I would say if any of the above fails, it's best to speak to your ISP to rectify. Te steps you've followed though wil help them zero in on what is wrong.

I hope all this helps
