Very Slow Wireless Connection [Lenovo AIO C40-05]

Hello!

Since I upgraded to Windows 10, about three weeks ago, I'm having a serious Wifi issue. The download speed dropped from 20Mb/s to less than 1Mb/s, and my upload speed pretty much did the same.

When running Windows' troubleshooter for my Wifi connectivity, it says: "Your computer appears to be correctly configured, but the device or resource (DNS server) is notresponding."

I then did the ipconfigthings, like ipconfig flushdnsand ipconfig registerdnsin the command prompt (with admin rights): I gained like half a mb/s. I launched a namebenchscan to see which DNs servers work best for me. After three hours, I finally got the adresses and selected them as default DNS adresses in ITP4 preferences. I gained 5mb/s for about 2 minutes, then it was gone. I reset my router: nothing. I ran an update scan for allmy drivers (took me a long time), and still, my problem wasn't fixed. I can't load even the most basic games or download movies, this is seriously getting on my nerves.

My computer is a Lenovo AIO C Series 40-05, I bought it about three months ago.
Anybody can help me? Please?

Thank you in advance,
