Rocket Titanium loses LAN
Interesting issue that we are experiencing where we have a RM5-Ti plugged into a Netonix-12 using 48V output. The RM5-Ti will randomly lose LAN. Rebooting the unit does not fix the issue. Locking down duplex on the RM5-Ti does not fix the issue. The only fix seems to be unplugging the cable from the Netonix or powercycling via Netonix. Ideas?

This is a known issue with Rocket M5 Titaniums and has nothing to do with Netonix, happens with any switch.
Search this forum and UBNT forums for more information.
I heard there was a firmware fix for this but not sure as I would never wast my money on a Titanium and use the Legacy Rocket M5 and get the same performance.

Re: Rocket Titanium loses LAN
Only reason for use of the RM5-Ti was for gigabit port as this link passes more than 100Mbps. Have you seen any benefit to using a PowerBeamM5 in this situation?

Rocket M5 and Titanum M5 are limited to QAM64
You will almost NEVER see more then 90+/- Mbps in one direction and that is with 30 Mhz or 40 MHz wide Channel with GREAT signals and perfect conditions such as GREAT SNR and relatively short link.
You should never run 40 MHz wide channel as it is spectral inefficient and seldom yields better than 30 MHz wide channel
If you are running 20 MHz channel then 72+/- Mbps MAX
So why do you need 1G interface for QAM64?
You do need 1g interface for QAM256 such as airMAX AC devices.

Re: Rocket Titanium loses LAN
I have the link pass more than 100Mbps and the speed tests show 150Mbps (but probably inaccurate, eh?)

Yea that is pretty hard to believe, I would like to see that.
What are you using the built in UDP speed test radio to radio?
Not an accurate test.

Re: Rocket Titanium loses LAN
I will post screenshots the next time I see it. We tried using AF5x on the link, but the DFS radar went crazy. Interestingly, it doesn't do this with the RM5-Ti.

How far is the link?
I like the Rocket AC Lite for PTP links.

4.7 miles. Do the AC-Lite go crazy like the AF5X?

I'm seeing pause frames on all AC radios, only a few of them trigger the pause frame control in the Netonix switches.
