Speeds fluctuating anywhere from 5 mbps to 700 mbps within minutes.

Internet started running badly so after doing the basic troubleshooting  I ran some speed tests and noticed the fluctuation. Thought it might be our old router so replaced it and replaced the cable modem (Deco XE5300 and Arris S33) Still having the same problem.  Also plugged the modem directly to my computer (by by-passing router) and got the same fluctuations. At a loss on what to do to fix this. (Side note paying for 1000 mbps.)

    Can you post a screenshot of your signal levels? See here. Also, when did the problem start and anything new or unusual around then? Last, how does the coax get from the pole/street to the room the modem is in? Any splitters/filter/amp?
