I just upgraded to Windows 8.1 yesterday. After that, I have not been able to access my home wireless network. The funny thing is, if I go to a Starbuck's or something like that, I have no trouble accessing their networks. The problem isn't with my router because my other wireless home devices, including Windows 7 machines are fine. After running the trouble-shooting prompt on my G780, it tells me I need to install an ethernet cable! I never had network connectivity problems with Windows 8.0 on this machine. I suppose it's possible I need a new driver, but that wouldn't explain why it works on public networks.

I am having this problem, too. I haven't checked on public wifi, but I have no wireless at home since updating to Win 8.1. My other laptop has wireless access at home, but my g780 has to be connected via ethernet cable. Your question here is all I've been able to find on the subject.

My Lenovo G780 worked perfect with windows 8. I updated to Windows 8.1. During the update, he asked for the network, he did see the router but when selected he said "beperkt", dutch for limited. I connected the computer with ethernet cable to the router and windows 8.1 installed perfect.
The problem is that I can not go on the internet because the computer says the network is limited.
I tried resetting the router, but nothing worked;
After restoring the computer to Windows 8, again I had perfect internet connection.
I tried again to install windows 8.1 but it was the same, lmited acces so no internet.
I also have a Lenovo Thinpad Twist. I upgraded this computer to Windows 8.1 without any problem. He didn't ask for network connection, he connected automaticly to the router and have perfect connection with the internet.
I read on the internet that with windows 8.1 updated drivers for the broadcomm network card is included.
Is it possible that those drivers cause the problem. Are ther others who have the same problem.
Excuse me that my English is not perfect.
I hope somebody can help.

Can you try one of the following:
1. Open Device Manager (press Winkey+R > type devmgmt.msc)
2. On the Device Manager, navigate to the Advanced Tab and set the following:
802.11n mode = disabled (if applicable)
802.11x / wireless mode= 802.11 b/g
3. On your router, disable Wireless N mode or set it to Mixed Mode (802.11 b/g/n)
2. Uninstall the Wi-Fi driver under the device manager and put a check on delete the driver software for this device
3. Right click on Network Adapters and choose Scan for hardware changes (this will revert to Windows 8.1's inbox driver).
If the inbox driver installs but doesn't work, try the following:
- For Intel 2230, check this driver)
- For Atheros card:
Atheros WLan Driver
- For Broadcom BCM4313:
BCM 4313 Driver
Hope this helps

I was succesful in resolving the problem of the limited internet. I upgraded again to Windows 8.1 and again he gave limited network possibllity, I chose to skip this page and windows 8.1 installed. But no internet connection.
The solution is very easy.
1) Open networkcenter
2) click on your connection, you get Wifi status
3) you click down left on property
4) then you click configure, you get the properties of the network apapter
5) choose the tab (stuurprogramma) driver
6) choose modify driver
7) The computer asks how you want to search for the driver; Choose (op mijn computer naar stuurprogramma's zoeken)= search on my computer for drivers;
8) you get a new window, choose (ik wil kiezen uit een lijst met apparaatstuurprogramma's op mijn computer)= I want to choose out of a list of drivers on my computer;
9) next window gave two compatible hardware. one from broadcom one from Microsoft. (the one from Microsoft was installed through the update from windows 8.1 under windows 8 it was broadcom.)
So I choose Broadcom cliked next and "wonder O wonder" immediately internetconnection.
Since then perfect internet.
<<<<<the problem is the driver from Microsoft
I hope this will also for you be the solution

I was able to resolve the issue by resetting my wireless router (a Cisco E4200). Not sure why that was the issue. Thank you to the others that posted solutions here. If I have any more trouble, I will keep these other solutions in mind.
