Has anyone seen a problem with the B5C and low throughput on TFTP ? This link is 36Km with 100% LOS - clearance is better than Fresnel 3.
A Mikrotik UDP Bandwidth test can go up to 110Mbps with no “Lost Packets” still at 0, but TFTP throughput across the link is less than 1Mbps. Typically it appears to run at about 400 Kbps.
The TFTP Server tests to a local device that is on it’s subnet at over 470 Mbps. There are no queues on the CCR1009 routers at each end. The switches are Netonix WS24A’s. No errors on the Ethernet interfaces on either switch. I’ve tried with and without Flow Control enabled on the B5C’s and the switch ports.
A simultaneous test in the B5 comes in at approx 160Mbps x 125Mbps.
Phy PER is typically less than 2%. RX EVM’s are relatively equal at ~20 to 23 dB on both ends of the link.
PHY Tx/Rx (Mbps): 405 / 360
MAC Tx/Rx (Mbps): 162 / 144
