[rugbymalc]

Hi I spoke with a sky advisor today who managed to get me connected by doing a hard reset on the router.  Tonight I am back to square one.  I have a connection which withing minutes disconnects.  I cannot get any work done please help.  I also can no longer get any connection at all one 1⃣ of my devices (tablet).  Which returns cannot authenticate connection.  I have tried the forget the network option rebooting and entering the network password again but no joy.  All in all I have wasted all afternoon trying to resolve this.  There is a problem I need some help
