Someone has asked me:

I have an X1 modem whose RX, NET and TX lamps flash at the same time in green. The 1.8 m antenna is well aligned on xx in a site with latitude xx and longitude xx. The RG6 cables are good quality and measure 30 m. The power supply is stabilized and the temperature is below 50 ° C. This modem has worked well for over a year before, and suddenly this change took place. What can be the cause? The down C/B varies continuously between 12 and 6 dB, while the Tx Pwr is -24 dBm.

Does anyone have any ideas ?

Best regards, Eric.
