Hello, I am new.

I've had this problem for the past few days now. I am connected to a network through a linksys router and can share files just fine but I am unable to access the internet from one of my computers.

I can ping ip addresses just fine but not domain names. Also in internet explorer and firefox I cannot connect to even IP addresses. The other computers on the network have access, it's just specific to this computer.

I've tried too many things to list here, if anyone could give me some advice and also tell me what information on my part you would need to help that would be great.


Heres my ipconfig /all

Thank you in advance.

Just some basic steps..

Ping your local IP (192.168.1.105). Ping your Gateway (192.168.1.1). Ping each DNS server (68.87.73.242, etc).

Things ok? Let's try a look-up. Open a DOS prompt (Start -> Run -> cmd). Look-up google:

C:\> nslookup www.google.com

You should see a section similar to "Non-authoritive answer:". If you do not, and instead receive an error message, then you are having problems with DNS resolution.

The last step I can think of is to try telnet (Start -> Run -> telnet):

Microsoft Telnet> open www.google.com 80
GET / HTTP1.1

(sometimes requires a blankline)
Did you connect? Get back any HTML? If so, your browsers could have some problems (Proxies, for instance).

I pinged my local ip, gateway, and each dns server and they all went through.

Here is my nslookup


C:\Documents and Settings\Admin>nslookup www.google.com
Server: cns.manassaspr.va.dc02.comcast.net
Address: 68.87.73.242

Non-authoritative answer:
Name: www.l.google.com
Addresses: 64.233.169.147, 64.233.169.103, 64.233.169.99, 64.233.169.104
Aliases: www.google.com

And here is what happened in telnet


Microsoft Telnet> open www.google.com 80
Conecting To www.google.com...Could not open connection to the host, on port 80: Connect failed
Microsoft Telnet>
