Limitations

Flexible Licensing is disabled in firmware and is not supported.

==Flexible Licensing is disabled in firmware and is not supported.==
What does that mean exactly?
I have a license that turns an EU device into a ROW device. Is this no longer supported with bad firmware?

[Fedor]

Flexible Licensing was used for Elevate SMs connection through the centralized licensing server.

Thanks.

[Eric_Ozrelic]

Can we get this added to cnMaestro cloud please? Thanks!

[Fedor]

@Anish could you please help us on that?

Thanks

Still seeing consistently poor performance with TDD TCP.

Wireless Link Test - ~300Mbps
Speedtest results - anywhere from sub 100Mbps to 150-200Mbps

[Fedor]

Massive performance improvements are coming in 5.7 version. Please let me know if you can be interested in 5.7 Alpha firmware.

Thanks

[jessearcher]

Sure, I’ll send you a PM

[DigitalMan2020]

@Fedor I would also like to try the alpha as well.

[DigitalMan2020]

@jessearcher is this a ptp or ptmp?

[jessearcher]

This link is in TDD PTP mode.

But I’m seeing the same TCP performance issues on regular TDD PTMP mode as well.

Hello @DigitalMan2020 and @jessearcher,

check your DM box. I’ve sent you 5.7.0 beta to try.

[SBBinc]

Do we still require the fcc version of firmware for 6ghz operation on 4600/4625?

[Fedor]

Yes, you do, you have to use FCC firmware until ePMP 6GHz devices don’t have AFC enabled by default.

Thanks

[DigitalMan2020]

@jessearcher thank you for your reply. I look forward in hearing your results if you would be able to report back after installing beta firmware.

[jessearcher]

Fedor sent me RC53, no improvement.

I’ve now been sent RC57 to try as well.

[DigitalMan2020]

Okay, shoot sorry to hear that.

[alex_torres]

Can I have that beta? Seeing some weird latency spikes.

[Fedor]

Just to keep everyone who is following that thread updated.

The link that is under monitoring right had significant retransmission % in DL and UL when we started looking into the issue reported.
At the first stage Jesse configured Max Rates in DL and UL setting MCS9 for both directions.
That has significantly improved Speed Test Result in DL and UL 180/85Mbps, but the DL was still far away from the Wireless Link Test Results(280/85Mbps).

Taking a look into TSFs files provided I can see 2% retransmission rate in Uplink and I guess that it causes DL throughput degradation for Speed Test.

Wireless Link Test uses UDP under the hood and is not sensitive to retransmission or packet loss, but Speed Test uses multiple TCP streams that are very sensitive to packet loss and retransmission. That is the most common reason for the difference between Speed Test and Wireless Link Test results.

Thanks.

[SBBinc]

Is anybody else seeing DL throughput lower on 5.6.1 vs 5.6.0-rc23 on link tests?

Wireless link tests on 5.6.0 in TDD mode were showing 1090/385mbps consistently, on 5.6.1 we are seeing 920/385.

75/25 ratio, short guard interval, 160mhz channel - large packet size/10 sec test
