Microwave wireless bridge

Hello-

I'm a web caster by nature, but I'm having some problems with a wireless to ethernet bridge that I use. I'm still trying to get details as far as name and model of the wireless bridge components from my network admin, but here is the general setup:
The transmitter is on a building about 500 feet away which beams to a receiver on the side of another building that I web cast from. From there it goes to a Netgear switch, which is connected to my laptop.

My problem is that after about 40 minutes or so of web casting, the wireless receiver stops taking the signal from the transmitter. I can unplug the receiver and it'll restart and then take the signal, but it takes about 3 minutes to reboot, not very good during a web cast. From anything I have said, can you help me?

Thanks in advance

Some new information:

The piece of hardware I'm dealing with is a Proxim Tsunami MP11

Tsunami is generally good equipment, I suspect you are have a overheating or power supply problem, causing it to die. try to keep the receiver cool and or replace the power supply.

Other problems could be:
A bad nic card causing a broadcast storm
Interference from other wireless devices nearby
excessive traffic over the bridge.

Isolating the problem may require further investigation, I would run an initial check of pinging the other side of the bridge without using alot of bandwidth for 30 mins or so, and see if it falls out after 3 min. If you are in windows just use the ping (ipaddress) -t and let it run for awhile. Example: ping 192.168.0.100 -t

Good luck
