Dell External Wi-Fi Switch
So the other day the WiFi stopped working on my Dell Inspiron 1720 laptop so after a little bit of troubleshooting and assumed the mini-PCI express wireless card was fried and ordered a new one from Dell's website. The new one didn't work either. Then I suddenly remembered that there was some sort of WiFi switch on the side of the laptop. I felt the switch and moved it moved it in the direction of "On" and it clicked! So it had been turned off! We move our laptop around a lot and somehow the switch had been switched to the off position accidentally.
