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.

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.

  • It built so I'm marking this as accepted. I'll have to wait and see if the new driver even fixes the issue though. – David Etler Jul 04 '15 at 15:18
  • So my wifi is still not working. With the new driver it started at 20 Mb/s but dropped to 6 Mb/s. Interestingly my upload has been consistently 10 Mb/s with both drivers. I'll open a new question since this one was about the driver not compiling. On second thought I'll edit this one. – David Etler Jul 04 '15 at 15:25
  • You can try to install 4.1.1 kernel as mentioned in the other question. But I doubt that it solves the issue, since there is actually same driver. But it is worth trying. @DavidEtler – Pilot6 Jul 04 '15 at 15:26
  • This worked for me! Thank you! +1 – Serial Jan 22 '16 at 08:13
  • @DavidEtler what worked for you? – muon Aug 12 '17 at 16:03

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.

  • I would but I'm not comfortable using an unstable build of the kernel. Just don't want to deal with other possible headaches. – David Etler Jul 04 '15 at 15:19
  • @DavidEtler But you can at least test if it helps, then remove that kernel, if it does not. That will give directions for me too if it is worth effort to update the driver in ppa. – Pilot6 Jul 04 '15 at 15:28
  • @Pilot6 Okay, I'll try it. – David Etler Jul 04 '15 at 15:30
  • @Pilot6 I installed the new kernel but when I boot into it I can't get X to run. I don't think I installed it properly; I've never manually installed a kernel image before. – David Etler Jul 04 '15 at 16:03
  • Did you install image and header generic files for your arch? If you have a proprietary video driver, it may not build correctly. You can always remove these kernel packages from console. – Pilot6 Jul 04 '15 at 16:06
  • I am using a proprietary video driver. I did remove them. Sadly I couldn't test the WiFi. Maybe a future update will fix my Wifi, this is frustrating. – David Etler Jul 04 '15 at 16:14
  • I have installed today this kernel and work good for 8 hours. Install the kernel in this order: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.1-unstable/linux-headers-4.1.1-040101_4.1.1-040101.201507030635_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.1-unstable/linux-headers-4.1.1-040101-generic_4.1.1-040101.201507030635_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.1-unstable/linux-image-4.1.1-040101-generic_4.1.1-040101.201507030635_amd64.deb after this sudo update-grub and the reboot. – PlugaruT Jul 04 '15 at 16:18
  • That's looks correct. You can remove it using dpkg -r <package_name>. Not file name, but only package name. I am leaving now sry. – Pilot6 Jul 04 '15 at 16:24
  • Okay. I'm turning off the proprietary graphics driver and trying the new kernel again. – David Etler Jul 04 '15 at 17:26
  • The problem persists even with the new kernel. – David Etler Jul 04 '15 at 17:56
  • In this case there seem to be no solution so far. @DavidEtler – Pilot6 Jul 04 '15 at 18:13

I have a new HP 17-x121dx that has an RTL8188ee and I've had nothing but problems with the wifi not connecting. After a week of searching and trying different suggestions, the one that seems to have worked is below....

Edit blacklist.conf that is located at /etc/modprobe.d/ and at the bottom of the file I added: blacklist acer-wmi

After rebooting the wifi connected automatically.

Hope this helps others who have been battling with this.
