Acer 3810T w/ Windows 7 - Won't Show WiFi Networks

Thread Starter 

I have an Acer Aspire 3810T running Windows 7. I was having problems with WiFi not showing up at times and when I would do a restart the WiFi networks would show up. I was told earlier the best way to fix this is to uninstall the WiFi drivers and then reinstall them. I uninstalled 2 drivers in Device Manager and both seemed to have to do with WiFi and I know one was Intel WiFI Link 5100 AGN. I then did a search for hardware to reinstall the drivers and the one listed above is the one that was found but I think it's missing another one that I deleted. Unfortunately no WiFi networks show up at all on my laptop. When I select the bars at the bottom right of the screen it's simply empty. I have shut down the system, restarted, and it appears my WiFi is on. If I select Open Network and Sharing Center and select Set up a New Network or Connection and select Manually Connect to a New Network for example it says "An Unexpected Error Occurred" so I know something is wrong with the networking drivers. Without WiFi the laptop is almost useless and I don't want to reinstall Windows 7 and have to set up everying again. Does anyone have any idea of what may be wrong and how I can go about correct this issue? Thank you for your help.

Is your copy of win7 a 32 or 64 bit version..Have you been to the Acer USA site and looked at the driver downloads for your model

The version of Windows 7 I'm using is 64 bit. I download a set of Intel drives off of Acer's computer for this model and ran the setup.exe file but that didn't work.  I even tried the find new hardware section but it didn't find any other hardware.  I have also done some google research but again have not come up with everything.  At some point I may have to reinstall Windows 7 but if I'm correct if I do that I will have to reinstall all software and set up all the settings, etc. again.

Before you do that, try doing a system restore to a point in time before this became a problem...keep in mind, that any data you have entered/programs/updates since that period, will have to be re-installed or readded.
Start>All Programs>Accessories>System Tools>System Restore....PS make sure you are on a/c power and not just battery

Thank you for the suggestion. I actually tried a system restore in the past and it didn't work.  When I rebooted everything was okay and it gave some kind of message how it was not able to complete the restore. I have many restore points though so will try it with another restore point.

What about letting Windows 7 updates picking the appropriate wireless driver for your model? So far this approach works for me for all the comps that I upgrade from either XP or Vista to Windows 7.

How do you use Windows Update to find the wireless drivers for my machine? I Just went into windows Updates and it gives me updates I can install but I don't see anything about selecting drivers for my computer.

Windows 7 updates would pick up the corresponding devices drivers if they are made available. Download Sandra Lite Free and verify your network device. Then try searching for it on the net, you might need to use a Vista version and then manually installing it,.
