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.

JM

BTW - can you get anything besides a T1 ??
Wonder what the cost of the T1 is compared to say DSL or cable ?

DSL has a flat rate pricing (but a TOS prohibiting sharing out your
connection). Depending on the speed, its priced generally from $30
to $90 per month for 1.5 Mbps to 10 Mbps.

T1 is distance priced. In a large city, it can be had for around $300
per month. But fifty miles from that city, it may cost upwards $600
per month.

that was a specific question for the OP can get in their area,
not a generic educational question....

BTW - you might try going to McD's, Starbucks, Panera, etc...
and see with a Ping and/or Speedtest to the outside world,
what kind of service they are using and "sharing" with their customers.
Does it test out as symetrical (T1) or not (DSL/cable).
