Slow internet connection via WIFI

Hello guys!
I got strange problem. Yesterday everything was ok. I got 60mbit connection(ethernet). It's normal when you connect via wifi that u got like 30% slower connection(i had about 40-45mbits). Today I got like 3mbits. I dont know whats going on. I think that the problem started after doing updates with ninite.com. I have tried almost everything! Reinstalling drivers, rebooting, scanning with AV, dealing with power management. What else can I do?

Lenovo G505s
Windows 8.1 Professional

Did not need the IPConfig info. Why are you also downloading updates from some unknown third party website? You most likely have downloading sketchy updates, that is causing your problems.

If you want to update software. Let the software update from the software manufacturer site that created the software. Using third party sites can allow you to infect your computer.
