I had my Dell 1525 since 2008, it came with Windows Vista Home Premium Installing Disc, and Drivers and Utilities Disc for this OS as well. But I had my Windows XP already and I used to work on it, so I installed XP and got drivers from Dell. I had no problem at all, until Microsoft decided to stop supporting XP, so I decided to wipe out my OS drive and install the Vista that came with my laptop. But the WLAN stopped working, I can't get any WLAN network. And also if I use external WiFi, it won't work until I disable the internal WLAN.
Any help for this issue.
