I installed ubuntu 8.04.1 yesterday on my laptop which is a Toshiba Sattelite Pro L40.
It has a Realtek RTL8187B wireless network card.
After installing Ubuntu the wireless network card didnt show up in network manager. Only modem and Lan card. So i installed the Windows XP 32 bit driver via NDISWrapper.
After installing it the wifi cards showed up. And i was even able to see the different wireless networks in my area, including my own wireless network here at home.
So i tried to connect to it and it asked for the passphrase and i entered it. But after doing this its like it isnt connected. Browsing with Firefox doesnt work, the pages fail to load. And i tried different programs that uses internet; email programs etc. Its like im not connected to the network. What am i doing wrong, please help!
