I believe i have tried every trick in the book ! I am able to access my router from my ubuntu desktop but not even a single site on the internet. i have installed the drivers for my pci wifi card following this procedure : http://steveswinsburg.wordpress.com/2011/03/12/how-to-install-a-d-link-dwa-525-wireless-network-card-in-ubuntu-10-04/
Earlier it didn't connect to the internet and kept prompting me for the password. after i installed the driver it got connected ! but now i cant access the internet and can only access my router. i deleted the resolv.conf file. I have also tried the "rkill" command and it shows it is unlocked. I have even tried pinging the ip's 18.104.22.168 & 22.214.171.124 and i get replies from both. I have also added them on my wifi configuration setup on ubuntu desktop. I am new to ubuntu but learning fast :-) These are the things i don't like about ubuntu, the simple tasks are difficult for a person coming from windows. I am using ubuntu 12.10. please reply at the earliest i would be very thankful.
