Mint 17 - Wifi connection dropping

Post by olly112 »

Hello, I've installed LM17 MATE on an HP 15 notebook. Unfortunately I randomly lose wifi connection. When it is connected, it is extremely slow; rendering it inoperable. I have tried a few fixes, none of which have worked. The laptop has a Realtek RTL8188EE Wireless Network Adapter.

First off, some system information: inxi -Fxz:

And here is the result of running the wifi script:

Solutions attempted:

I have disabled Ipv6 support, as follows:
sudo su
echo "#disable ipv6" >> /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" >> /etc/sysctl.conf

(followed by a reboot)

I also tried updating the driver as follows:
sudo apt-get install --reinstall linux-headers-generic linux-headers-$(uname -r) build-essential dkms git
git clone https://github.com/FreedomBen/rtl8188ce-linux-driver
cd rtl8188ce-linux-driver
make
sudo make install
sudo cp -r firmware/* /lib/firmware
echo "options rtl8188ee ips=0 fwlps=0" | sudo tee /etc/modprobe.d/rtl8188ee.conf

However the wifi is still faulty. I would really appreciate any help: this is really causing me a headache!

Thanks in advance.

Hi,

seems you have also a problem with the graphic card driver
ati (unloaded: vesa,radeon) FAILED
but let's first check your wifi and it's environment (linux drivers enforce a lot more correct settings then windows drivers)

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && \chmod +x wireless_script && \./wireless_script
It will download a script and create a file named wireless-info.txt or wireless-info.tar.gz in your home folder with wireless information so we can see the condition of your wireless at the time. The MAC address, WPA key and WEP key are removed for your security. Paste contents of the wireless-info.txt or wireless-info.tar.gz file at http://pastebin.ubuntu.com or alternatively http://pastebin.com/ then post the link here in your question.

Hi :) here are the results: http://pastebin.com/yjBzDSVQ I seem to be having a rare moment of decent internet! (possibly because I'm sat right next to the modem) I;ve also noticed that the wired connection does not seem to work at all! :/

Yeah I noticed the graphics driver. Having a few other unrelated problems too with this install, but one thing at a time! :3

ok,

here we go.
you are using a mixed mode wpa and wpa2, set your router to wpa2 only
your country code is not set.
check this to make sure you have everything sorted and to understand why wpa2 should be used.
