Thanks for that, useful info. I've been trying to read up on the
standards, but that has saved me some time :) I was originally thinking
that I should go for the 200Mbps units, but given that they are around
£52 plus postage from Solwise (the cheapest I've seen I think) I wasn't
in a major rush. I still have the problem that the machine I'm most
interested in using it on is on a surge protected extension, which no
doubt will cause problems :( I can see a use with one or two customers
though, and when I spotted some 85Mbps units at £23 each it started me
considering experimenting. £69 for the 3 units I'd like to use for
myself is a lot more affordable than £156 - although I may still hold
out as I'm in no rush and have wifi working well enough.
It is the PC that is causing me most problems. When booted into Windows
is will generally get very slow after a while, and is majorly prone to
locking up. That seemed sort of normal for Windows though, and simply in
need of a reinstall to tidy things, but when I installed Ubuntu 7.04
onto the machine I got a bit of a surprise. If I leave that running for
a while (couple of hours ish) I get a message detailing that an IRQ has
been disabled (I don't have the exact text handy) and the mouse and
keyboard become close to unusable. I can just about manage to get the
cursor to control a shutdown. Every hardware diagnostic I've tried has
given the machine a clean bill of health, but this would indicate a
hardware issue :(
