I bought dell XPS L502x with Intel centrino wireless N 1000 a year ago. I havn't had any problem with the wifi until the last 3 months. I get access to internet but it's slow and sometimes doesn't open websites. I have another computer that works perfectly with the same router.

for inspiron 15 3521-8275 bios is flashed to a06, i have tried the latest driver from dell site, version 9.2.0.504, installation is okay, but i can not connect to any access point. is there any wireless driver for windows7 64 bit that is actually working? thanx in advance, dejan

Just inherited this computer. It's loaded with viruses, ransomware, etc. Don't have any of the CDs that came with it and won't put it on my LAN until I know it's clean. I do have an original XP Home Edition install CD I used to install XP on a Mac Pro running BootCamp.
