WISP / File sharing problems?

Hello. I was wondering why a couple users running P2P programs can
effectively disable my provider's wireless network? The entire network will
lag while these people are using their software, but then when the ports are
blocked, it gets fast again.

I know they aren't downloading at more than 384 or 768k or uploading at more
than 128k (their normal limits). So does anyone have any reasons or am I
just set up with a poor WISP?

BTW, this is also a rural area, so I can't imagine they have many customers
on the tower?


Thanks

What's the connection to the internet? Satellite, DSL, T-1 ?

2.4Ghz, 802.11b wireless connection. I have gotten my information from their
system admins about the problem, just trying to understand better what is
going on.

Thanks

No No. I mean what is the backbone connection? At some point thier wireless
device has to plug into a hardline. Be it a T-1, T-3, etc type connection.

The reason I asked, was if it was say, a satellite connection (which for our
purposes will fill the role of hardline), there are limits to how many tcp/ip
connections can be active at any given time, regardless of how much bandwidth is
being used. I discovered this the other day on my system. I share a satellite
connection with 3 other persons, and one was using a p2p app. The bandwidth he
was using was insignificant, but his program was using 44 tcp/ip connections,
out of our max shared total of 45 allowed. hence, everything slowed to a crawl.

I had this to happen on my network. It was just one guy but he had
several (I still don't know exactly how many) computers constantly
uploading and downloading from Kazaa. His client radio pretty much "took
over" the access point, slowing it to a crawl or a stop for everybody
else. And this is on a full T1 from a tier one provider. His signal
strength and signal quality wasn't anything special, it just seemed that
once his stream of data got going through the AP, the AP was ignoring
all other clients. I got it stopped, but yes, one client can jam up a
wireless network. The WISP needs to either block P2P data (which can be
difficult to do since many programs just keep trying different ports
until it finds one not blocked) or do some heavy bandwidth throttling on
that client, or use a bigger hammer on their head.

That makes sense. I'm pretty sure it's a T-3.

Unless thier Wireless Access Points are connected to the same building the ISP
is in, I'd find it pretty hard to belive it would be a $10,000/month T-3..
