Hey!

I'm running a multi-drive system. One of my drives is my Windows 10 boot drive, another is my Windows 10 storage drive, and the third is my Ubuntu 16.04 general use drive.

On my windows 10 environment, my internet is incredibly fast and responsive. On my Ubuntu 16.04 LTS environment, however, my internet takes ages to receive updates or load a webpage, to the point where it is almost unusable.

This has been an issue for several months now, and being the obsessive googler that I am, I have attempted to locate the source of the issue and solve it myself. So far, however, not a single one of the common fixes have resolved this issue.

This has been over the span of several months, and unlike Windows, I very frankly have no clue what I'm doing with Linux, nor do I understand any of the fixes that I have attempted other than simple things such as uninstalling the default network manager and installing wicd.


As such, I have no clue what command line information I need to provide in order to be helpful to anyone that wishes to help me. I'd appreciate it if a pro could walk me through discovering and solving the issue.


My wireless adapter is a Realtek RTL8192CU Wireless LAN 80211n USB 2.0 Network Adapter.


Thanks for your help!

Hi,

Welcome to TSF! I would like to start by asking if you have access to hardwired internet at your location. I see that you are using a wireless card. I would like to see if this is an issue with the internet, or an issue with your wireless. I will then know how to better troubleshoot your issue.

I do not have access to hardwired internet at my home. I do know, however, that the wireless card works just fine when I boot up Windows 10 rather than Ubuntu on the same machine.

I would like you to read and follow all the directions for this post. It will have some directions for you to follow. Not all the directions will apply to you. If you don't understand something just ask and I will help you. You will need to be in Ubuntu for this to work. I look forward to your next post!

Hi, sorry for taking so long to get back to you. Have a look at what this user over at git made it might work.

This custom driver seems to have resolved my issue in its entirety. I'm getting the same internet speed on Ubuntu as I have been on Windows 10. Thank you so much!
