Can connect to wireless router but can't browse internet

Question

I have a Dell Studio 1450 running Fedora 17. I installed a new wireless router in the office recently. And everybody apart from me is able to connect to the internet via it. Google revealed http://forums.fedoraforum.org/showthread.php?t=276645 which is very similar to my problem. Here are output logs of some commands for you to help me.

UPDATE: It is not a problem with fedora, it is my laptop. I tried with other distros (Ubuntu 12.04 anh Bodhi Linux) and the same problem exists.

Answer 1

Anurat - Try assigning a static IP address instead of getting it from DHCP to your wireless interface and ping the gateway. Your router might be blocking traffic from a certain IP range. In particular, try to use an IP address assigned to another client in your network that has Internet access.

Answer 2

It was a problem with my hardware. The new router was running an 802.11n network while Intel WiFi link 5100 card in my Dell Studio 1450 doesn't support it. Other laptops in the office being comparatively newer were operating perfectly.

Solution: Changed router settings to run on b/g mode and everything is back in order now.
