I have install win 7 for my dell inspiron 6400 laptop but no modem & no video controler


You need to go to Dell Support pages online and download the drivers for your laptop model, if they dont show a windows 7 driver then try the vista or xp one they list, should still work.

No Internet


You need to check first if the wireless switch is turn on.If it is on, check the function key for the wireless. Some computers have function key. Sometimes it is combination of fn and f5. Press those keys at the same time and you should see a pop up window and check if the current status is on. If it is on, uninstall/reinstall the wireless driver in device manager. and restart your computer. If this didn't work. You need to do re installation of your operating system.

Excellent signal but not able get access online


I always see if the wireless works withOUT the burden of the encryption. Half the time the key was wrong just to spite me. Then add in encryption after you've proved everything else works. Another not-so-funny thing is the function key RadioOff (blue function key + F2 I think) gets hit by accident sometimes and turns the radio off without telling you. You can see a msg in the Dell Wireless software on the..second tab I think, when this toggles off...--Jeb

There is NO built in microphone with this laptop. You will need to purchase an external microphone and plug it into the mic in socket.
