[Bug 1320070] Re: Realtek Wifi card RTL8723BE drops connection with MSI enabled

 

Tips for RTL8188EE [10ec:8179] and RTL8723BE [10ec:b723] users: those
hardware modules have MSI compatibility issue, on some certain platforms
they work fine with MSI but break connections without MSI, on some other
certain platforms it's opposite. You could try to toggle its module
parameter "msi"
