This morning I noticed my internet was down. So I logged into my modem page and noticed that the status was stuck on a cycle of Syncing->Synced->Ranging->Ranged then starting over with Syncing.

RX power appears to be normal at around -45 dBm
SNR stays around -1 dB
Resistance is a constant 2 Ohms
Attenuation fluctuates during the cycle from 0 to as high as 29 dB

I have Power Cycled my modem several time and get the same results. I have double checked all connections from the modem to the dish for moisture/damage/connectivity and all is clear.

My questions are why is the attenuation spiking so high and what is causing this cycle of attempting to connect but failing?

I've had light rain here over the past week but this issue only just started this morning. Overcast covering most of the state but no storms or even moderate rain.

The modem status readings are meaningless until the modem and satellite are communicating. You can get the best help by sending an email to Include your account number and a description of your problem

Ignore the attenuation during the lock process.
What you are seeing is typical behavior at that stage.

If your Rx SNR remains that low, there is no way it is going to lock.
Your signal should be MUCH stronger - varies with beam & your location within a beam
If SNR remains that low, you have a service call in your future
