Ubuntu 11.10, Wireless Connection but no internet

Question

Right after installing Ubuntu 11.10 using the wubi.exe file, I tried to surf the web in Ubuntu. My wireless connection is found without problem, but firefox doesn't manage to load any pages. Can somebody help me out? Please let me know which results of commands in the terminal I have to post.

Answer 1

I have also the issue after installing Ubuntu 11.10 (oneiric) on two IBM T40 one with internal WiFi the other with NEC adapter, at the setup sequence the WiFi was working perfect, after restarting , the both PC WiFi got invalid gateway: 192.168.1.1 instead of 192.168.1.10 as my router is set. to resolves this issue at the moment I'd setup the adepter manually, very easy;

1. Right click on network icon,

2. Choose the WiFi you use (exp.HOME 1) go to EDIT CONNECTION

3. Choose wireless, take manual option , click ADD fill the IP you give to you post (exp, 192.168.1.5) valid with ENTER; give mask (255.255.255.0), valid, give gateway of your router(exp. 192.168.1.1).

4. now add the DNS ( open CONNECTION INFORMATION to see the DNS is available.)

I'd like to know why the WiFi adapters don't toll the good GATEWAY.
