Changed service, now flashing blue light

I changed my service from 940Mbps to 1gig, since it's essentially the same number but $5 cheaper. A few minutes after I made that change, the light on my Q1000K went to flashing blue. I chatted with a polite flowchart-following rep who had me factory reset the Q1000K (no change) and is sending a tech out in two days.

​

Since everything was working fine until I changed the rate plan, seems like that was the problem. Is there a different way to re-sync things that will be faster than waiting until Monday?
