Lenovo G500 WiFi Problem

2014-05-16, 15:10 PM

Hi

 

 

I bought a Lenovo G500 around a month ago (Windows 8.1, Intel Core i7 2.20 GHz, 8 GB RAM, 1 TB Disk, Broadcom 802.11n Network Adapter).

 

 

I have a problem related to wifi connectivity. When i'm at home, no problems with networking. But when i'm at the college, where network is public and realized with a proxy, my lenovo sees the network, but can't connect to internet because the network is "unidentified" and i have a "limited access". My other PC and my HTC One continue to work fine with the routers and access points placed in the college. I tried everything: reinstall wireless drivers, reset winsocks and ip, disable Windows and Comodo firewalls, disable the energy options of the network adapter... but nothing seems to change, and every time i have the same problem: nothing fixes the issue.

 

If anyone has any suggestions I would be very grateful!

 

Thanks

hi marcello33,

 

Welcome to Lenovo Community Forums!

 

Try this,

 

StepA.

   Open Device Manager and check under Network Adapters,

Remember what brand you wireless is ex. Intel, Realtek, or Atheros

   right click on it and click Uninstall.

      Place a check on the Prompt that says Delete Driver Software for this device.

Now click the View option at the top of Device Manager and select Scan for driver changes.

    Open Network adapters again right click and click uninstall driver 

Now

    On the same prompt for deleting the driver check if there is a check box still.

 

If yes Repeat the step until you don't see the checkbox anymore. then proceed to Step B.

If no Proceed to Step B,

 

Step B.

    Restart the computer.

 

Download and Install the driver below for what wireless you have

 Intel WLAN Driver 

 WLAN Driver (Atheros, Broadcom, Realtek) 

 

Restart the computer after installation and Reconnect to the wifi you're having issues with.

 

Let me know your findings

Cheers!

Solid Cruver

I have an issue with my Lenovo G500 laptop. 

 

My parents bought it me for my birthday in July from K&Co, and I have recently found out that I cannot connect to any wifi properly without a little wifi adapter. It will connect to one, and then after a few minutes disconnect again. At college, I simply can't connect to either the "open" or the "secure" network. I can't get anyone to work on it as it will then void the warrenty that I have on the laptop. What can I do? I need my laptop for my college work and homework

I'n G400s I had same trouble when I'm using a proxy connection. I removed the installed driver and install default windows 8.1 driver and work.

 

 

If you need more diagnostic you can run any linux in USB pendrive, and test, I do this and worked better than Windows.

I too am having the G500 intermittent wireless disconnects. To fix i have to go back into wireless access list, turn wifi off, pause then turn on again. 

 

I tried downloading the drivers as specified elsewhere on this board but it didnt work.

 

Current state is that i am on windows 8.1

 

The hardware device is Intel centrino wireless N135

 

Showing driver as MS windows intel v 15.10.0.12 dated 25/6/13

 

The laptop has been reset back to out of box condition,it has then picked up some updates.
