[Solved]Frequent WiFi disconnection on Mint 18.1

[vatzcar]

Hi,
On my computer my WiFi gets disconnected frequently while WiFi manager applet shows as connected. My WiFi adapter is Prolink WN2201 USB. Though I've tried with different WiFi adapter and same problem persisting. And that same WiFi adapter is working well under Win 10, so, I guess the problem is with the linux installation itself. Previously I had Mint 17.3 and there wasn't any major issue with this WiFi adapter. Please help me as I'm unable to use my computer.

Thanks

It might be wifi power management causing the disconnects

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/* 

Reboot

Thanks Jeremy. It was really helpful. Initially the problem was solved but after 2/3 reboot the problem persisted. I've checked the value of /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, and it's set to 2. Though turning WiFi off and back on from wireless manager applet is connecting to the network. And I've to do that every now and then to remain connected to the network.

Hopefully you can do this

Code: Select all

sudo apt-get update && sudo apt-get install dkms build-essential

Code: Select all

git clone https://github.com/pvaret/rtl8192cu-fixes.git

Code: Select all

sudo dkms add ./rtl8192cu-fixes

Code: Select all

sudo dkms install rtl8192cu-fixes/1.10

Code: Select all

sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/

Code: Select all

sudo cp ./rtl8192cu-fixes/8192cu-disable-power-management.conf /etc/modprobe.d/

Reboot
It might help to edit the network connection and set IPv6 to ignore or disable
