Annoyingly the wireless broadband I've had from back in the Freeserve days is playing up and it's probably time to 1. try out a new wireless modem router or 2. change providers. I've called Orange and they're claiming it's probably the box. Of course they're saying that as they don't support it because I didn't buy it from them.
The lazy option is to buy a new box and try that. See below.
The smarter one would be to switch ISPs, maybe even one that'll give me a free box, and leave Orange to stew in the cesspit of their own making.
