Wifi not working


May 30, 2016
After i installed windows 10 on my lenovo g500. The internet doesn't work most of the times however other devices are working.
Tho on the wifi symbol it shows that the internet is connected.
Sometimes it says there is no internet connection or connection is interrupted

Things I've already tried (none worked):
-uninstall intel centrino wireless N 135 and restart computer
-disable and enable wifi
-change DNS server address

Please i desperately need help this is driving me mad. Its been a month

Please do try these troubleshooting steps that may help.
- First download and install the wifi adapter driver from Lenovo.
- Here's the link: https://download.lenovo.com/consumer/mobiles/0dg3019f.exe
- Once downloaded, open Device Manager and uninstall the Wifi Adapter completely.
- Do install the downloaded driver once the wifi adapter driver has been uninstalled.
- Reboot the laptop once installed and test it again after the reboot.
- And lastly, if all these will not work I would suggest reinstalling Windows itself.
