Not a plea for help (for a change), but an oddity which I wonder if anyone else has come across. Family with 2 laptops and an Epson wireless printer. All had been OK, but suddenly no print from either laptop. I tried all sorts then, in desperation, tried one of my spare routers. All OK again. BT were persuaded to supply a new router and all is well.
That was two weeks ago. Had a call today from another village. Same problem and same cure.
