I have tried attaching a file to an email, ( one that I do every day ) size about 3mb, but today I have tried attaching it and whilst the indication 'Attaching File' and the square icon appear, the small rotating circle just carries on forever and no indication at the bottom of the square icon appears.
Any suggestions gratefully received.
Others have reported this problem in the past and a factory reset of the homehub by pressing a pin into the recess button on the rear for about 20 seconds resolved it.
Thanks for the replies and I have solved the problem by switching the power off to the Hub (2) and left it overnight, just attached the usual file in a reply today and all is back to normal.
I tend to agree with huntwr.
