Laptop Wireless Network Issue

No Wifi Network On Laptop

Acer Aspire 5570 laptop will no longer find our wireless network or pick up any others in the area...we checked the front switch and wireless is enabled...also tried the function F3 key and again, wireless is "on". Any other suggestions?

Either the wireless adapter is not turned on, or its not installed properly, what I mean is, while it probably is properly in its place and not disconnected from the computers mainboard, it could have a driver problem. 

You could check on that by right clicking on your my computer or computer icon on your desktop or find it from the start menu and right click on it. Select Manage from the list, from the management window, click on device manager on the left side.

Now on the right side the device manager should be open, from there look / open 'network adapters' and or look for any devices for ? or ! or X mark over them, these all would indicate a problem or that the device is disabled.

If there is a red X that means that the device is disabled right click on that device and select enable and your problem should be solved.

if its a ? mark right click on it and select properties from the new window that opens read the status message and post it to me here and I can give you further instructions.

If its anything else or if its not listed, or if it is listed, just post here and lets see what we can do.

I followed your instruction and in the Device Manager under Network Adapters both the following options were marked with an ! 1. Intel (R) PRO/Wireless 3945 ABG Network Connection 2. isatap.ed.shawcable.net The message for #1 noted above was "Windows cannot load the device driver for hardware. The driver may be corrupt or missing (code 39) Message for #2 noted above was again that Windows could not load the driver (code 31). "

Right click on the device and select uninstall, restart the computer, the device should get installed again automatically if not we need to download the drivers from acer website, let me know how it goes.

SOLVED: I downloaded the drivers and it is up and running. Thanks!
