Hi All,

At home, we currently have a WRT54G wireless router set-up on our main
computer (which also has an internet connection). We then have another
computer which has a NIC (I think that's the correct terminology) with
a little antenna connected to it. These two computers 'talk' to each
over the wireless network, and share internet, files, and the printer.

I have two questions about this network:

1) We would like to add another desktop computer to this network. Does
this involve simply purchasing another wireless NIC for the new
computer? If so, is it any NIC, or does it have to be one specifically
for the WRT54G wireless router?

2) The other question relates to speed and reliability. When nobody is
using the main computer, then using the internet on the secondary
computer is very fast, and barely drops out (when it does drop out,
within a few seconds, it has re-established connection). Problems
arise when someone is using the main computer for the internet. Not
only is the speed unbearably slow, but it frequently drops out. You
really cannot use the secondary computer for the internet at all,
which as you can imagine, is very annoying.

Can anyone help with either of the above issues. I suspect the first
is a much simpler answer than the second.

Thanks in advance,

Ilan
