Hey guys I'm having some issue with my rtl8188ee network card. On Windows I get ~30-40 Mb/s whereas on Ubuntu 15.04 I get ~5 Mb/s. However, the issue comes and goes; often after disconnecting and reconnecting my WiFi temporarily jumps to the proper speed, only to recede again shortly.

In search for an answer I came across this thread; however I was unable to properly compile the driver (here's the error I get when running make).

I was wondering if anyone knew how I could manage to compile the driver properly, or if anyone has another way to fix the slow WiFi speeds in Ubuntu 15.04.

In order to give as much information as possible, here are some diagnostic information:

some guy's wireless info script

Edit

I successfully installed the new driver thanks to @Pilot6 but problem persists. For more information, my download is the only speed affected. Upload is consistent at 10 Mb/s. I really have no clue what to do at this point. I know the hardware is fine because in Windows I don't have any issues with wireless.

Second Edit

Disabling IPv6 worked for a while but speeds dropped back down again. Problem remains intermittent. I don't think this has to do with the wireless repeater I'm using because all other devices work fine. Further, upload speeds have been entirely consistent, so I doubt it has to do with the signal or interference.

Alas, 5 Mb/s is sufficient for my daily routine. I only hope a future update will solve the problem.

Solution 1:

You can install a driver from my ppa. It should build.

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

and reboot.

Solution 2:

Or you can try to install latest kernel 4.1.1 from here:http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.1-unstable/

I have a rtl8723be and after updating to this kernel all problems were solved, now the speed is very good and the wifi is not disconnecting.
