I've seen posts about this before, and the answer has been that it's a problem at the gateway -- could be something like weather, for example, or a technical problem -- you may just have to wait a bit until the problem is solved. Perhaps the tech gurus @GabeU, @Gwalk900, @BirdDog, or @C0RR0SIVE can give you more info.
Hughes modems are rather 'chatty' in respect to the data they record ... and it is a lot of it.
Much is going to depend to the number of occurances and the duration of the events.
Weather between your terminal and the satellite can be an issue. Just as important is the weather between the satellite and your Gateway facility.
The 'Book' has this to say about a 11.2.1 error condition:
Assuming no severe weather conditions at the terminal or Gateway locations
and no Gateway issues (e.g. SatGW down), then this problem typically points
to an installation issue at the terminal site.
If possible, verify the outroute tuning configuration parameters for the
terminal. Given the Beam ID and Outroute ID, lookup what the Over-the-Air
Downlink Frequency and Symbol rate should be. Verify that the terminal is
using the same outroute configuration. Also, verify that the L-Band tuning
frequency is as expected based on the OTA frequency and the installed LNB.
Thanks for posting and welcome to the community! I pulled up your account to check on your system, and currently it should be working normally. Although right now I do see you're currently subject to the Fair Access Policy, so your speeds will be slower than usual.
How often are you seeing the 11.2.1 state code?
Your cooperation, patience, and understanding are much appreciated.
