[Cable] SB6120 Stats Through Router?

Again this evening, 28/1 cable service in Mississauga is hit and miss at best (currently seeing 1.02Mbps up and 0.21Mbps down). TSI’s Current Cable Outages page does not show anything is in trouble. Not sure if it is the daily TSI degrading of service or if there is something wrong in my area. Is it possible to gather line stats from my SB6120 from behind a router or do I have to connect directly to it? If it is possible, how to view the status? Thanks..
