We saw similar problems with the ports locked at 100/FDX - Set everything to Auto and speeds were there.
I posted that on the UBNT Forum, but never got an answer.... -Gary- ----- Original Message ----- From: Steve Barnes To: Ubiquiti Users Group ; WISPA General List Sent: Tuesday, September 07, 2010 6:44 PM Subject: [WISPA] PowerBridge 5M I changed out a StarOS backhaul with a pair of PowerBridge 5M radios, 4 mile link. I Have an odd issue. The link is perfect 130MB 99% Airmax. UBNT Speed test from radio to radio is 84Mb. Now the interesting issue, both radios are plugged in to MT 493AH 4.11 OS. Running MT Bandwidth test from MT to MT TCP speeds are horrible. 14 Mb Dn and 6 Mb Upload. We tried all kinds of tests finally realized (after the climber was on the ground and in my office) that if I do a speed test from the PowerBridge station to a Rocket plugged into the same Mikrotik that I get 14 Mb x 6 Mb through a 100% wired connection (UBNT to Port-2 MT, Port-6 to UBNT Rocket) We had tried different ports to no avail and I test from MT AP thru MT 493AH to 2nd MT AP and I got 50 Mb x 50Mb. Then I realized that 2 hops across the wireless link I had a NanoBridge. A test to that across the wireless side of the link gave me a 30 Mb x 35Mb. So it come down to a single PowerBridge radio that either has a bad ethernet port or a bad POE/cable between the UBNT and MT, or some kind of incompatibility between the MT and PowerBridge. All ports are set to 100Mb FDX not Auto negotiate. This MT 493AH is relatively new with Gig option. When running speed test there are no ethernet errors or packet errors on the MT. What else can I check from the ground. Unit is 250 ft up and requires a climber I don’t have daily access to. Will the PowerBridge 5M work with 12-15 Volt. I know it wants 24VDC I don’t currently have that on this tower but had no issue with others on different towers at 12 V Steve Barnes RC-WiFi Wireless Internet Service ------------------------------------------------------------------------------ -------------------------------------------------------------------------------- WISPA Wants You!
