I’m struggling with a 5GHz bridge I’ve made between two homes.
I’ve installed two SXTSQ 5AC with a distance of 120 meters between the antennas.
On the AP side, I’ve a 2.5Gbps internet connection, and I would like to send as much bandwidth as possible to the other building.
I’ve configured the connection to work on 802.11 (I’ve tried also NStreme and NV2 but the performances get even worse).
Actually they are working on channel 5580 (80/40/20MHz eeeC), after a scan I can only see other networks on 5500 20Mhz and only from the AP side.
I get an overall CCQ on the CPE continuously oscillating between 85% and 99% and a signal strenght of -53/-50 with the TX rate stable at 866.6Mbps and the RX dropping from 866.6Mbps to 360Mbps randomly (of course it’s not random).
I would like to know if you have suggestion, cause in this conditions, I can’t reach throughputs in UDP on the CPE higher than 485Mbps in send direction (that it’s fine cause my internet connection have only 500Mbps of upload bandwidth) and 300/320Mbps in receive direction (the one that i care the most).
I’ve also increased HW retries to 6 to avoid rate drops due to multiple frame retransmission.
Hope someone can give me some hints.
(already readden all the related other topics, but didn’t found a solution that fits).
You’ve had 36 link drops. There is a high probability that there is interference in the form of swaying tree branches, or the masts of access points are swaying. It is also possible that the link is disconnected due to radar detection.
For stable operation in the 80 MHz band at maximum speed in the channel should be a signal level of -51 or better. You have -56.
For outdoor use, you must disable the short guard interval (SGI).
That’s all I can tell from these screenshots.
You have not provided any L1 data for a proper analysis.
The data rate of about 500 mbps is the limit for the AC standard in the 80MHz band, for mikrotik.
The link drops are 99% due to modifications I’ve made testing the link…
About signal strenght, I think I should be able to reach -50dbm, I’ll try. At the moment I’m using default tx power and rx sens as suggested on Mirkotik Wireless FAQ.
About L1, what you need to know?
The WAN is an FTTH connection with an ONT ZTE F6005 with 2.5Gbps Base-T port, connected to the 2.5G port of my RB5009UG with a UTP Cat6 cable, the SXTSQ 5AC AP is connected to one of the 1G ports with addition of the PoE Injector supplied with the antenna. The cable handling PoE and data is a UTP Cat5e.
On the CPE side, same cable type from the SXTSQ 5AC to a L1 switch with 8 1G ports from Netgear.
The bandwidth test has been performed with the integrated BTest of the ROS. (I know is not the best way, but at the moment is the only solution I have to exclude NIC problems of my devices that would interfere with the measurement).
