For some reason Windows 8.1 on my Dell Computer keeps dropping its WiFi connection when I leave the computer for a while.  Its perfectly okay whilst I'm working on it but as I know its best practice to leave the computer running all the time and therefore extend its life, I don't want to keep closing down and rebooting.  Also of course it stops collecting emails which is especially annoying and I have to completely exit Outlook and restart the computer or run through Network diagnostics for it to mend the problem of its own making.  I suspect the computer and Network card is configured to close down automatically but I'm afraid after scouting round the Dell site the only instructions I can find for investigating and correcting WiFi problem with Windows 8.1 appear to be for a completely different operating system.
