Wireless network fails to take me beyond my router

[Peter N. Spotts]

Folks,

I've just come across something I've never experienced: I have a laptop
connected to wifi. And I can assess the router settings with it, which
means the laptop and router clearly are communicating. But when I bring
up a browser and try to open a web page on the internet, I get an
"address not found" error in the browser.

I'm using a Linksys WRT54G-TM router.

Two other laptops going through the same router via wifi are currently
getting onto the web with no problem.

Any thought on how to tackle this one?

With best regards,

Pete

see if you can ping an external IP number like 64.233.161.104 (google)

if ping fails, it's a routing thing, your default gateway on your laptop
should  point to the IP of the router.  netmask shouldbe 255.255.255.0.

if you can ping it, you might have a problem with your DNS, and therefore
cannot resolve names like "yahoo.com."  your DNS server
should point to the router's IP, whose cache should be set to external
servers when it connects to your provider's IP.

Many thanks. That did it. Odd that I haven't had to add the router's
IP address manually on my other Ubuntu 9.04 machine on the same
router. But there we are..

Thanks again!
