setting wifi in ubuntu for dell vostro 1400 with dell wireless card

there is no specific wifi card driver in ubuntu 8.04 for dell vostro 1400. so we have to install the windows driver with ndiswrapper. but ndiswrapper can only be used in terminal. so we have to install the gui version named ndisgtk.

following are the steps in installing these things

1. open synaptic package manager
2. search ndisgtk. if it is found then skip the steps 3 to 7
3. if not found open settings>Repositories
4. open the tab Third-party software
5. select the two items and close the window
6. press ctrl+r
7. after completing the download, search for ndisgtk
8. select it and press ctrl+p to download it
9. after installing, close synaptic package manager
10. download this link and save the file in a folder.
11. now open terminal and go to the newly made folder
12. type unzip and press tab button to show an .exe name and press enter
13. now type sudo ndisgtk. you have to type the password here
14. press install new driver and browse to the driver folder inside our newly made folder
15. open the 32 bit folder or 64 bit folder as your ubuntu 32/64 bit
16. select the inf file found there
17. press install
18. close ndisgtk
19. type sudo iwlist scanning
    
20. most probably you will get the wifi connectivity
