Wireless AP Re-Broadcasting Packets

Hey Guys,

I hope a wireless expert can help me out with something that has stumped me for the past year. This issue has occurred at the last two places that I have worked at and I am wondering if it is just normal behavior.

When I am using wireshark to hear the broadcasts in our network, I see the same packet being re-broadcasted anywhere from 3-5 times. I get the original packet first from whatever device on the network. Then I get a few more right after that seem to be encapsulated with a new header by our wireless AP and rebroadcasted multiple times.

What would cause a wireless AP to do this?

Thanks,
Steve
