Wireless Woes

If wireless works in the computer repair place but doesn't work at home, kindly be advised that it cannot be a driver error because if it was a driver error it would have done the same thing in the shop. And it doesn't, therefore as far as we're concerned there's nothing wrong with it. Flicking the front button probably isn't going to solve anything and the problem is usually caused because something else that uses the same part of the Spectrum (electromagnetic, not the ZX81) is also in use, most probably next door.

Wireless is a very fickle thing; sometimes it works, sometimes it doesn't. It's no more dangerous than cordless telephones, satellite signals and TV signals and its very prone to atmospheric conditions, in the same way you can sometimes pick up ITV Yorkshire on terrestrial TV when you live in Oxford. One customer came in before Christmas and proudly decreed they didn't want wireless anything as it was dangerous. The fact that they were practically living in a world of wireless transmissions anyway didn't seem to occur to the customer - even cable TV is essentially a relay of satellite broadcasts.
