I recently dual booted Ubuntu 16.04 with Windows 10, and I'm new to Linux. I have a lenovo Ideapad 500, 16 gb RAM, AMD FX 8800.
After I installed Ubuntu the wifi wasn't working and I found a solution where you had to install the driver in a new directory (I think it was this).

So my wifi is working now, but the problem is that the connection is slower than it is in Windows 10, the download speeds are slower and I confirmed with speedtest.net (In windows I get4-7 Mbps and in Ubuntu I'm getting ~0.5 Mbps). I tried a solution where you had to add a nohwcrypt command to a driver file (I think), and this solution. But it doesn't work, the internet is still slow. This is the output of sudo lshw -C network:

  • Before any further troubleshooting make sure you have the correct wireless encryption settings: WPA2-AES only, not any WPA/WPA2 mixed mode and certainly not TKIP. –  Sep 25 '16 at 19:11
  • @CelticWarrior I'm connecting through the network manager and it has only 2 options: WPA&WPA2 Personal and WPA&WPA2 Enterprise. How do I set it to WPA2-AES? – Patricio Garcia Sep 25 '16 at 19:26
  • The settings are at the router managing that wireless network. –  Sep 25 '16 at 19:37
  • @CelticWarrior Okay, I set it to "Authentication: WPA2-PSK" and "Encryption: AES", but the problem persists. – Patricio Garcia Sep 25 '16 at 19:59
  • See if there is any change after sudo iwconfig wlp2s0 power off – Jeremy31 Sep 26 '16 at 14:07
  • @Jeremy31 No changes. Also I tested the wifi in my university network and it was fine. So I think it has something to do with my modem or modem configuration. – Patricio Garcia Sep 26 '16 at 23:11
