bandwidth

I have switch providers and have run into some problems with bandwidth limitations. I have more bandwidth then before, but there are performance issues.

The router is connected to a 100mBit port, but they limit it to arbitrary settings (in software I imagine). It seems when I go above the limit, the provider starts to drop packets beyond the limit (This is what they said they do as well). Is it possible the previous provider did something like queuing packets above the this limit before dropping them? Is anyone aware of not only what can be done, but what is typical?

Also, is there anything I can do on my Cisco router to help this situation? It would seem I am pretty helpless if the packets are dropped before they reach my interface (The traffic that is high is inbound to my network).
