Ok I have a Acer Aspire 6930, this is my first laptop so please bare with me I am not used to this quite yet. My wireless worked for a couple days and now is saying I need to turn a switch or use a key function combination to turn my wireless back on. Where the heck to I find this?? This is becoming very frustrating! Please Help!
Have a look at the Acer manual (or their support site). There's usually a physical switch on the front edge or side of the case and an LED. Alternatively it'll be the Fn key and a Function key (F1, F2 likely).
Unless you are very confused, it probably isn't to do with the wireless network key (encryption password).
I have an acer computer the aspire 3680, and have the same problem however, when I attempt to turn on the botton it will not turn on it just jumps back into the same position. The only way I can connect to a network is to restart my computer everytime.
