Doesn't it allow you to save the configuration to disc before resetting, then restore it? It should.
The last time I used and checked it it did have that feature, sadly if the settings are corrupt saving it, factory resetting it and then restoring the settings would result you back to the same issue.
This is due to you saving the corrupt settings as well.
What I try to do is every time I get a firmware upgrade I do a factory reset and then reset things back up and then save everything.
Sure it all takes time, but I bet it would be less time than having to check everything when bad things start to happen.
It is unlikely to be the configuration that is corrupt. If it is, you would soon find out, and not have lost much time. Then at the end you could save it to cover the same happening again. I always like to have my router config backed up locally.
I wonder if its just s config issue to do with the lights on the hub, has the OP tried to turn off the lights in the setting, I think there is a setting for that unless I am getting mixed up with a different modem / router.
