Bug Description

Using Ubuntu with my Netis WF2116 300Mbps Wireless N USB Adapter, my internet connection will often slow to a screeching halt, videos fail to stream properly from Youtube, I get DNS issues reported by Chrome and Firefox in which my current connection cannot "find" a website although connected, and my connection will cut in and out intermittently though I have set the MAC address of my router as the BSSID. Windows 10 does not give me these issues.

UPDATE: I ran into a newer driver within a PPA assembled by Launchpad user "bodyakov", https://launchpad.net/~bodyakov/+archive/ubuntu/wi-fi . Attached to this message is the (AMD64) ftl8192cu driver, version 4.0.2.9000-2... I am currently running the driver version 3.19.0-15-lowlatency.

I am going to add the PPA and/or install the driver manually and I'll post the results shortly.

UPDATE - CONTAINS FIX!
I tested out the PPA and though performing a software updater cache reset and update check, I still had to manually install the .DEB file as the Software Updater told me that there were no updates available.
After a quick install and reboot of the computer, my average internet speeds multiplied by 18.107 times!

Possibly the network manager was misreading the Wireless Adapter to begin with which didn't lead to any forced updates via the Software Updater either with or without the PPA.

Given that this is reportedly fixed by updating a driver, it's not a bug in NetworkManager (so I'm removing the task, we don't need to track it there).

Also, as a further data point, I wonder how running a low-latency might affect things like wifi performance. I think it's not impossible that it has a bit of an impact on it as well.

no longer affects: network-manager-applet

Also, since the attached files aren't patches but rather deb packages, I'll go ahead and undo the patch tag and flags.

Could you try and communicate with Bogdan Koval (bodyakov), and see if you guys could come up with a proper patch in diff format for the changes required? Then attach it here again and subscribe ubuntu-sponsors again.

Jeb Eldridge, to advise, there is not enough information for upstream developers to address your issue. Hence, please answer all of the following questions:

1) The latest release you reported with 15.10 has been EOL since July 28, 2016 as per https://wiki.ubuntu.com/Releases . Hence, to see if this is resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

2) In the latest Ubuntu version, unplug all USB WiFi devices, plug in only the Netis WF2116, execute the following in a terminal and post the results:
usb-devices

Please note, do not install any 3rd party software when executing the above.

3) Could you please provide all the missing information from https://wiki.ubuntu.com/Kernel/LinuxWireless ?
