Acer Extensa 4420 Network Adapter

I have had and Acer Extensa 4420 for about 6 or 7 months. During that time it's worked just fine. As a broke college kid, I can't afford my own internet, so I've been borrowing wireless from a few different sources around my apartment complex (with permission, for those of you who want to kill me now). Up until a couple days ago it had worked fine, but I tried to install a wireless receiver to try to boost my signal, and then everything went to hell. Now it will only connect to one AP (unfortunately the weakest one), the acer utility keeps telling me when I try to connect to any of the other, that there is a problem with my LAN (this computer has never been connected to wired internet). For a few days, the internet would connect and I could use external clients of online games (PokerStars, etc.) but the browser would not load. I've run system restore back to the oldest restore point, about a week before it freaked out on me, and the internet works, but the rest of the problems still exist. Any suggestions?

    Router was a Dynex DX-WGRTR, supposedly it was able to run in ad-hoc mode, but apparently not...

    I installed the router software using the disc that came with it. Windows is notorious for holding on to remnants of files after program uninstallation, so I ran the system restore to ensure all the files were erradicated. The issue with the internet completely not working was resolved, but it is still VERY slow and I am still unable to connect to APs that I used to rely on.

    With that router did you install any software for it at all?

    Uninstall any software related to the wireless receiver. Go into add/remove programs to do this. Then reboot and see if you can connect properly. What is the wireless receiver you tried to install? Make and model of it I mean.

Acer Extensa 4420 overheating

The laptop must be dismantled to access the motherboard, buy a can of compressed air attach straw. Now remove fan and the heatsink, blow out all open ports and fins on the heatsink and fan, next! remove thermal grease from the processor and heatsink with rubbing alcohol and a paper towel, now! apply fresh thermal grease to the processor and heatsink, "small thin layer evenly spread" now assemble, "solves most heat related issues"

How do I enable bluetooth in my Acer Extensa 4420-5963

Actually Acer use the same laptop case for some of their models, so the acer 4420 doesn´t have built-in bluetooth, you won´t find any driver for the bluetooth cause that reason. I have an extensa 4420-5910, have a bluetooth switch in the case but no bluetooth, if you check at Acer´s web page it say thet some models doesn´t have built-in bluetooth but the switch is in the laptop case... On the other hand, if you install an external bluetooth device, the case switch will be usefull to turn it on and off.
