As I know nothing about Dell Latitude D520 Just wondering if it has already got wireless installed and you have to switch it on. Some laptops have a switch to turn it on others you have to press Fn+f2 others may be different.
There should or might be a switch or different keys to press on your keyboard to start the wireless connection.Broadcom should be your wireless connection. maybe try Control panel.Administration Tools.Services ,And scroll down to WLAN and make sure it is set to Automatic. But like I said you should have a way to switch the wireless on from your keyboard or a switch.
Hi buteman, I have pressed the F2 & Fn and yes the WiFi icon appears and is switched on, but still no connection. There is no WLAN in the Services list, should there be? I have downloaded the drivers for the Broadcom PCI mini card but still no joy.
Sorry Scubaman not sure what you would have to do next. I know very little about wireless connections just a bit that I picked up when trying to fix my granddaughters laptop. She had 2 connections on her system tray. 1 was the local area connection and that had a red cross on it as she was using the wireless connection and of course the other was the Wireless connection. I am assuming that you have a wireless router installed it would be a matter of right clicking the wireless connection to see if it is picking up any wireless signals and of course if it picks up yours you would need to put your password on to it to use it. Like I said I know very little about wireless connections so will have to leave it for someone else to give you the help that you need.
