Lenovo G505 Wifi Problems - Limited Connection, No Connection, and Dropped Connections

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,

WiFi Issues With G505

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.

 

Please advise.

 

Thank you in advance.

Re: WiFi Issues With G505

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.

Re: WIFI LIMITED CONNECTION

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.

Re: WIFI LIMITED CONNECTION

device manager, right click on your network adapter, go to update driver, then "browse my computer for driver software, then"let me pick from a list of...." , uncheck the "show compatible hardware" check box and finally select the appropriate driver, in my case it was the Intel centrino wireless n 2200 (microsoft).

This fixed all of my problems,

Re: WIFI LIMITED CONNECTION

I've done that already but still says limited connection. Lenovo needs to get up their lazy ass and release a working driver for broadcom
