I agree that Trango needs a change log. I thought they had one, but can't seem to find it right now.
We recently upgraded an Apex18 and an Apex11 with v122 firmware. The reason the Apex18 was upgraded was because it would just stop passing data even though the rssi, BER, MSE and link lock status all showed good. So far we haven't seen the issue again, but this problem only surfaced every month or two. Jury is still out if the firmware resolved the issue. The reason the Apex11 was upgraded was because one side would "flap" MSE readings from -35 to -17 causing ACM to shift modulation from 256QAM to QPSK and even lose link lock status at times. The duration of the issue the couple times we've seen it was relatively short...several minutes...before clearing up all on its own. Trango support seems to think there could be some sort of noise being injected into the radio from the Ethernet port, but wanted us to upgrade firmware first before continuing troubleshooting. Since the upgrade we haven't seen the issue, but again the jury is still out as not enough time has passed since the upgrade. Other than that the rest of our Trango licensed links have been pretty flawless.

We have a link in production that is using an older firmware that I plan to upgrade to the latest, v1p2r2. I'm unable to find any documentation regarding what this firmware actually fixes or what known issues it has. Does anyone have the details or have this firmware in production? Thank you. ---------------------------------------------------------------------------- ---- WISPA Wants You!
