WIFI Speed Very Slow After Windows 10 Creators Update

[account_disabled]

Hi,

I have updated my G50-70 to Creators Update - Windows 10 Home Single Language x64 and ever since i have updated i noticed that my wifi speed has been very slow on my connection which is 90Mbps.

When i open the status of Wifi it shows the link speed of 54Mbps and am getting around only 20Mbps Download and Upload Speed.

So i did reset of my modem and re-installed the drivers and when i restarted and once again i viewed the status of my Wifi, it shows the link speed of 150Mbps and i got a full speed of my broadband plan i.e 90Mbps Download and Upload Speed.

But at the end of the day, mostly i will put my lap on sleep mode and when i turn my lap back, it shows wifi is disconnected and when i try to connect it says can't connect to this network and finally i forget that wifi and again connected but again my link speed has been reset to 54Mbps and now am again getting 20Mbps Download and Upload Speed.s

Fianlly i tried to update the drivers using Driverpack Solution and IOBit driver installer and i got the link speed of 72Mbps which gives 55Mbps of Download and Upload speed but soon after the restarting of my lap, it reset again to 54Mbps of link speed.

I don't know which one is causing problems to my WIFI Driver.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
