I have recently installed Ubuntu 16.04 beside Windows 7.
I use TP-Link TL-WN821n.
Ubuntu normally installed,
seems that USB stick driver was installed automatically.
but the internet connection is very slow (in Windows is normal).
I run connection speed test in Ubuntu it shows:

  • 0.90 MB/s - Download
  • 1.00 MB/s - Upload

While my connection is 30MB/s Download, 3.0MB/s Upload (speed test in windows shows that).
i tried to search about how to fix the problem, run more than 7 solution and nothing got fixed.
Can anybody help me with that?
Regards,

I had same problem and it was resolved reading and doing it like here, blacklisting the driver they said.

Internet speed really slow in linux but not in Windows

My TP-Link TL-WN821n often disconnected from the WiFi network and didn't reconnect until I forced it. The following link fixed that issue https://github.com/pvaret/rtl8192cu-fixes
