* Many teachers will be tempted by the prospect of having a fast, always-on connection at school and home. Most broadband services offer consumers a DIY broadband kit that consists of an ADSL modem and some installation software. I recently installed a broadband system at home and can confirm it’s all a bit hit-and-miss. Installing an ADSL on my laptop PC via a USB port was a cinch and everything worked well. But when I tried the same thing on a desktop PC, the modem would power off every few minutes. The solution can range from buying a powered USB hub to installing a special USB card in your PC. From the experience of using broadband on my laptop, if you can receive an ADSL service in your area, then it is well worth the effort of moving from a dial-up service to a broadband connection at home.
