My Lifebook U745/14 has intermittent wifi issues. Sometimes when I look at the Network Connections, the internal wifi connector is visible - and other times, it is simply not there so cannot connect to it.
If I restart, it most often 'reappears' and connection then works fine.
Any suggestions of how to keep it from disappearing or alternatively, is there a h/w fix that is worth doing.
Machine is 2 years old
