Maybe silly Q. Why doees speed from my router vary from 54 (which I'm
sure is wrong) down to 1.0?

802.11g operates at a maximum of 54Mbps - so why do you think it is
wrong?

> down to 1.0?
Wireless LAN speed is dynamically adjusted by negotiation between the
end points to try to maximise speed whilst maintaining a reasonable
signal quality, hence acceptable error rate.

Variation between 54Mbps and 1 Mbps is excessive if the end points
are physically static, and suggests there is an interference problem.

It's either interference from some other 2.4GHz device, or you have an
old buggy version of Intel Proset that does that without much
provocation. In theory, if the access point detects any transmission
errors, it will reduce the speed until the errors go away. If you
don't like this feature, you can set the wireless speed to whatever
you find amusing in the wireless access point web based setup utility.
However, if it really is interference, you'll be sending or receiving
errors instead of data.
