Bad weather at the location of the ground station (and this is always in another state from where the modem is) can also affect connection. But the issue can also have other causes.
Is the code 22.3.19 or 22.3.1? What does it say next to the code? Usually there is an explanation of what it means.
- You can wait until a HN rep replies to your post here (they're not here 24/7, so the reply may take a while). You will recognise the reps because they have MOD next to their names.
- You can call the 800 number and talk to a phone rep
The reps here can check your modem remotely, so please leave it plugged in so they can access it.
EDIT: When your phones and TVs weren't connecting, did you do anything to try to fix the issue?
