Some forum members have reported a variety of Wifi issues with their G505 laptops. Their reports range from showing "Connection is limited", to Wifi connections dropping repeatedly, to being unable to make a Wifi connection at all. I combined multiple threads in order to assist forum members with troubleshooting solutions.
If your G505 was upgraded to Windows 8.0 or 8.1 and then lost connectivity, or you recently purchased a G505 running Windows 8.0 or 8.1 and are unable to connect, try following the instructions posted by Vikramsbox to restore the connection through the Lenovo Communications Utility.
For non-Windows 8.0 or 8.1 users, start troubleshooting with the basics:
After trying those steps, if you still experience a Wifi issue with your G505, other troubleshooting steps have been noted in this thread. This includes a whitelist of accepted replacement WLAN cards posted by Topmahof and a 3rd party driver which resolved wifi issues for Miila and Jessemck125. Please note that while Lenovo does not support 3rd part drivers, it may be an option to consider if your laptop is out of warranty and none of the suggestions in the thread resolve the issue.
Thanks for your contributions,

Good afternoon all!
I recently purchased a G505 from Best Buy.
I have only run into one issue.
My WiFi will go from connected to "Limited" connectivity about every 10 to 20 minutes. I can disconnect from the router and reconnect, and it will fix the issue temporarily.
Connectivity is fine with all other devices and was fine with the previous laptop just a day before I purchased this one.
Thank you in advance.

First is to update your Atheros/Broadcom driver for your G505 here:http://download.lenovo.com/consumer/mobiles/wlan117w8.exe
From what I understand, the situation is that you get limited connectivity while your other devices that are connected to the router gets uninterrupted internet access.
After updating your drivers, you can try to flush your DNS cache by copy and pasting this code to your notepad and saving it as FlushDNS.bat
@Echo on pushd\windows\system32\drivers\etc attrib -h -s -r hosts echo 127.0.0.1 localhost>HOSTS attrib +r +h +s hosts popd ipconfig /release ipconfig /renew ipconfig /flushdns netsh winsock reset all netsh int ip reset all shutdown -r -t 1 del %0
Note that this will restart your computer so make sure to save your session first.
Here's the link that explains the benefit of flushing DNS: http://www.sevenforums.com/network-sharing/144365-network-posting-tips.html
Hope this resolves your random "limited connectivity" problem.

Yep, me, too. I actually posted a message below, but no one's answered yet. Maybe there will be strength in numbers, here. Anyway, everything worked fine until 8.1. Not my router, either as my other devices work fine.
