Lenovo Wireless Issue

[toonKev]

Good evening all, I recently just installed Linux Mint on my system after reading a lot of information and trying to take it all in, still having a lot of fun learning

Anyway the issue I seem to have at the minute is that my Wifi on the laptop only will cut off after browsing for a little while, the only way to get it working again seems to be restarting the laptop. I'm not sure why this is happening or even if there is an easy fix?
Any help/adive would be great!
Hope I have added this information correctly:

Hi! Which model of Lenovo you have?
In my Lenovo G40-30 (Ideapad) I had to "blacklist" the laptop:
(in the terminal)

Code: Select all

sudo modprobe -r ideapad-laptop
sudo rfkill unblock all
rfkill list all

Then, create a new archive in etc/modprobe.d/
The archive can be named for example “myblacklist.conf” (the name can be different, the key detail is the termination .conf). Inside this archives you must punt this line: blacklist ideapad_laptop

For this model, this solution works.

Using updated drivers from backports usually works for that chip

Code: Select all

wget -N -t 5 -T 10 https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.18.1/backports-3.18.1-1.tar.xz

Code: Select all

tar -xf backports-3.18.1-1.tar.xz

Code: Select all

cd ~/backports-3.18.1-1

Code: Select all

make defconfig-rtlwifi

Code: Select all

make

Code: Select all

sudo make install

Reboot

See my answer http://askubuntu.com/questions/588226/t ... navailable but use the ideapad_laptop.c that is https://www.dropbox.com/sh/vuci43ve6nt9 ... t9vea?dl=0

Tried what Jermey said so hoping that works, my Lenovo model is the b50-30.

Cut off again this evening!
Fount this code on the Ubuntu forums about the same issue.

Code: Select all

echo "options rtl8723be fwlps=0 swlps=0 swenc=1" | sudo tee /etc/modprobe.d/rtl8723be.conf
