Check that the laptop's "wireless disable/enable" switch is in the enabled position
Check that the computer is actively searching for a wireless network.
Ensure the settings on your computer match that of the router, for example, make sure a thunderstorm didn't knock out power which knocked out power to the router, which forgot its settings. If this is the case, you'd need to re-load those settings.
Check that the broadcast unit for your wireless, the jetpack or the router, is powered on and sending a signal.
Reboot (complete power off and power back on). If the wireless now works, disable your operating systems' power management for your laptop's wireless card.
check the cards and be sure you have teh drivers for them and even load teh drivers again just in case..to check eh cards you need to go to device manager and see if they present in order ..to do that click right on computer icon , select properties, and than device manager .. In the list ..look for the cards and make sure they are not in yellow..If they aren't so ..it means you just need to activate and make the settings right for them .. usually the wifi card need to be enabled ..and if you use it ..(or try to ) ..just press teh button for to activate it ..and try to scan for teh networks from the task bar tray function ..select the correct network and connect .. the only way that it is not active ..is if it it need enabling or it is not installed or is damaged ....If all these are covered ..it have to work .. For the LAN card ..same thing ..check the driver ..than go to network places and select to show the connections ..enable it if it is not ..and check the protocol for the LAN connection (tcp/ip ) or what ever connection you use.. In last case contact you ISP and ask for guidance for to connect proper .
Drivers have to be active as well as the device, try this procedure.

In some Acer models, there is a software switch in Start/All
Programs/Acer Launch Manager. If this is missing, you need to reinstall
since even with the WiFi hard switch activated, this application is required. This is so especially if a
new/clean/OEM install of the OS has been done on the laptop.
In some models, there is a hard switch either at the front or at the side to activate the internal wifi (and bluetooth). Still in other, there is button on the leading edge of the computer which also serves as an indicator lamp,
Some models also have WiFI enable/disable in the BIOS/CMOS setup.
Still others have a button along with the Easy-launch strip (top) together with the those for email , bluetooth , Acer Arcade & others.
As shown above, depending on the specific model/region version of your laptop, the WifI activation can be varied.
Hope this be of help/idea. Pls post back how things turned up or should you need additional information.
If I were you, I would let your windows manage your wireless network on the computer with vista. Also you might, If you haven't already tried using your install new programs in the control panel, As long as you have the sprint software downloaded in your laptop windows should still recognize the wireless connection, Try letting windows manage it from the Network properties and there should be an option there that lets windows manage you network. try it see if that helps you out. If not write back here and let me know we can try another route. Sorry you having problems.
1) The wireless hardware is turned off in the BIOS. Reboot and check to see if there is an entry in the BIOS for the embedded wireless card and if so make sure it is set to ON.
2) The hardware is not recognised because the drivers are not properly installed. Check in DEVICE MANAGER to see if the wireless appears at all, and if it is in an error state. If so, re-install latest drivers from the manufacturer's web site.
3) Other software necessary may be missing. Some machines have wireless manager clients that they need to access the card. Check on the manufacturers' web site for these utilities, and if found, install them and reboot watching for new (different) problems to arise.
4) You could have buggered wireless hardware, but this seems pretty unlikely. Some wireless cards are add-ins and can be removed from the laptop motherboard by accessing them through a door on the bottom of the unit. If that is the case with your machine, power down the unit and remove the wireless card. Check in the hardware manager to make sure no device errors for the card remain, and if they do, remove the hardware by right-clicking on the error device icon and clicking on REMOVE HARDWARE. Then, power down and re-insert the wireless card and reboot and try a clean install.
