L23 ptp link

RouterOS Wireless Networking
1

Hi at all,

I have set up a 25 km ptp link with two L23 devices and two 60 cm dual pol parabolic antennas, the link is stable, with a troughput of 180- 190 Mbps in both directions, signal is around -80 db in rx, but there isn't way to measure the single chain rx signal. In first installation I have a trouble with one polarity because one connector there are faulty and I solved only after I unplugged the cable and noticed that the signal disappeared completely.

I am very satisfied with the performance of this routerboard, especially the receiver part, I would be completely satisfied if there was a product with a few more db on the tx, I also noticed that the power tends to drop above 5800 mhz (or the receiver loses performance).

There are a way to implement measure of single chain or is a limitation of the driver?

This also allows you to optimize the separation between the two chains and obtain less interference between the two chains (by rotating the feeder). I would like to see an upgrade in this regard regarding the wireless part because I notice that the competitors are more careful in this direction.

Best Regards

Nicola

I already requested chain information in SUP-190934, this was in June 2025. The answer was then:

Unfortunately the Qualcomm drivers do not support to show separate chain stats and shows only combination of them but if we will be able to ever update that we will most likely do it.

Thank you very much, but I also noticed another thing, the devices show an association speed of around 309-344 Mbps which apparently is not possible for a signal of -80 db this occurs for a frequency over 5800 MHz (it seems like a bug in the RSSI reading) while if I move the frequency around 5700 MHz the reading changes around -60 dbm which makes more sense given the speed in which it is associated
