.. . . on limited funds.

I will try to be concise, while providing adequate info.

I handle IT for a property management company that recently took over
management of an RV park. This park provides wireless internet for the
residents. Currently, the wireless system consists of 3 ez3 APs
(http://www.e-zy.net/outdoor/3plus/) mounted on poles at the front, middle,
and back of the park, each connected with a cat5e home run that plugs into a
10/100 unmanaged switch that connects to a Linksys WRT54G rev 2 that I
flashed with dd-wrt r23 sp2. The internet pipe is a T1 provided by a local
LEC. We estimate that during the summer the network will need to support
30-50 users.

There are several strategic considerations that need addressing, and the
first one in my opinion is bandwidth management. Just in the last 2-3 days
we've seen the inernet speed drop to a crawl when one or two users start
hogging bandwidth with what appear to be massive downloads. The status
tools in the APs showed download/upload ratios on these users in the 20/1
range. I've got to find a way to impose QoS on the network.

But a big issue for the company right now is cost, so I have very little
budget to work with. So, if possible, I need to use whatever free and low
cost solutions I can come up with.

Thank you for any assistance. Please let me know what information I've left
out.
