Firstly, I have a billion wireless router, one of the 7404 models an
"n" version, and I found the wireless was crap. It can't make it to
the next room - constantly dropping out. I have an old linksys wrt54g
that is far better, covers the whole house and is rock solid. I
turned the wireless in the billion off and use the linksys.
Look at the channels. There are 11 to 13 channels in b/g in Australia
but only three are sufficiently far from each other to not interfere.
That is 1, 6 and 11 (or 2,7,12; 3,8,13 etc). You may need to get a
scanner or scanner software and map the channels and strength and
choose ones that are 5 channels away from the bad ones. Unfortunately
some APs channel hop these days. Also with an AP you might find
putting it in a particular spot is better. ie near the ceiling.
It might be worth talking to someone who is a radio expert and getting
them to have a look. Many other devices can interfere with wifi in a
much worse way. Wifi APs are reasonably cooperative with each other.
You might try 802.11a or 802.11n which both work in 5GHz band, so not
so many people use it.
Anti-wifi paint or metal mesh screens in the right places.
Antennae. You might try antennae that are directional on your AP.
I had friends who had a problem with wifi as their house had massive
stone walls. They got an ethernet over power adapter and set up
another AP. Of course people may be using them in your building
