Hi Tortugaverde,
The “Limited Connectivity” means that the PC has successfully connected to the router, but the PC wasn't assigned a valid IP address, so you can't actually get to the Internet. It would be great if you can answer these questions to assist you in a better way.
1) Did you install the latest Windows 8.1 compatible Intel Wireless LAN drivers (Version: 16.8.0) on the computer? If yes, was it downloaded from the Lenovo website?
2) Apart from updating to Windows 8.1, did you make any recent changes on the computer prior to this issue?
3) Do you have any third party security program installed on the computer?
Since you do not face any issues with the other Windows Vista, 7, and 8 devices on the same network, this issue seems to be due to the incompatible drivers installed on the computer. Let’s first run the Network and Network Adapter troubleshooter and check if that provides any useful information regarding this issue.

If the issue still persists, then I would suggest you to try installing the latest Windows 8.1 compatible Intel Wireless LAN drivers which are released on 26^th^ Jan 2014 from the Lenovo website and check if that resolves the issue.
Method 2: Uninstall and Reinstall the latest Wireless LAN Drivers
Before installing the latest drivers, let’s uninstall the old existing drivers from the computer. Please follow these steps:
Step 1: Uninstall the Device Drivers
a) Press “Windows Logo” + “X” keys on the keyboard.
b) Click on “Device Manager” from that list.
c) Search for the WiFi adapter device from the device list, right click on it and then select “Uninstall”. On the un-installation window, if you have an option: “Delete the driver software for this device” you may select that and then remove the corrupted drivers from the computer.
d) Follow the on-screen instructions to complete it and the restart the computer if prompted.
After the restart, please open the Device Manager again and then click on the “Scan for hardware changes” button. Check if Windows 8.1 detects the WiFi adapter device and installs an appropriate driver automatically. If the issue still persists, then try the next step.
