I appreciate the detail message. Two antennas are about 150 meters apart using yagis on the top of the buildings. The line of site is pretty clear, it however is going over the street where the traffic could be busy at times. Main building is 5 stories high and the other is 3 stories high. Cable is the 150foot coax from Cisco and run is about 120 feet of so.
They are both transimitting and receiving at 11.00mb for the most part. I don't have any wired ethernet connection plugged into the non-root bridge yet as we are still in the test phase. I doubt it, but could this be a problem? Thanks ""neal r"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > How far apart are the antennas? What antennas are you using?
