Need to restart my modem every few days

This has been really frustrating. Althought I have seen similar posts, but there were no concrete solution. We signed up for 1000MB internet around 2 months ago, but the speed drops to a few MB every few days; we need to restart the modem (a new ARRIS SB8200) to resolve it. I just restarted the modem and below is the tatus report:

Re: Need to restart my modem every few days

Can someone tell me whether the signals are normal? There's a 1-3 splitter involved, should I change it? Many thanks in advanced.
