Well i bought a laptop without researching to see if the wireless card works with linux.The card is a realtek 8821ae. I am currently running Windows 10 Mint dual boot. the Mint version is the latest Mint Cinnamon. The wireless card drops out alot and just does not work well with linux So I'm going to buy a usb wireless adapter. Do i have to disable the current card to get the usb version to work? If I disable the card will it be disabled under windows? Thanks for your help. Dan :x

It might be power management issues that can be fixed with

Code: Select all

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

Code: Select all

echo "options rtl8821ae ips=N" | sudo tee /etc/modprobe.d/rtl8821ae.conf
Reboot

Hi jeremy,
Could you please explain in detail what does those commands do? I have brand new Lenovo Y520, I hope sticking with it for a long time and I want to stick with Linux for a long time, so I want to know more about what issues can my Laptop hardware have with Linux Mint 18 and beyond

best regards,
Alex

They disable wifi power management in Linux Mint 18, the second command is specific to the wireless card
