I have dual boot 13.10 and Windows 7. After the installation of the driver rtl8188ce in both Ubuntu and Windows, Ubuntu holds the connection, unlike before. But there is a very big difference in navigation speed.

What could be the problem and how can I fix it?

  • Please tell us which network card you have. Post the output of lspci | grep etw. – terdon Mar 09 '14 at 16:24
  • How did you install this driver? Did you install the exact same driver for Windows as well? What steps have you taken so far? Please explain everything. – Alvar Mar 09 '14 at 16:31
  • and alvar and terdon....so. because it doesn't work, as Windows after these procedures...can i buy a lan usb...there is a model d-link that in 13.04 Works well, i could buy it? In Your opinion, can i resolve the issue with this way? – user249168 Mar 10 '14 at 13:52

If you have administrative priveleges over the router, I suggest you change the WPA2 encryption method to AES. It is more secure. Also, if the router uses WPA and WPA2 mixed mode, change it to WPA2 only.

Second, if the connection is made as expected, but seems to drop for no apparent reason, there are a few things we can try:

sudo modprobe -r rtl8188ee
sudo modprobe rtl8188ee swenc=1

Also, find your country code here:

iw reg get

If it shows as 00, that's a one-size-fits-all...maybe code. Let's try setting your code explicitly. Find it here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Set it with:

sudo iw reg set IS

Of course, substitute your actual country code, if not Iceland.

Finally, tell your system you wish to always use your preferred network rather than roaming to another: Ubuntu connect drops. Worked for a while then started dropping again

In order to make some or all of these permanent, we'll need to amend a few files. First, tell us if the problem is resolved.

If none of these steps help, I suggest you compile a later version of the driver. Please obtain a temporary wired ethernet connection. Please download this file to your desktop: https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.13.2/backports-3.13.2-1.tar.gz Right-click it and select 'Extract Here.' Now open a terminal and do:

sudo apt-get install linux-headers-generic build-essential
cd ~/Desktop/backports-3.13.2-1
make defconfig-rtlwifi
make
sudo make install

You will get a warning about signing that you may safely ignore. Detach the ethernet, reboot and let us hear your report.
