Hi RCN, I'm a 4-year internet-only customer. I'm mostly very happy with the product, but recently I've been seeing service degradation, both during the day and in the evenings. My main frustration is that this hampers my ability to play Google Stadia (~20 Mbps @ 1080P), which has happened several times in the past month (including tonight). I work on this service so I know I'm being served from New York.
I'm looking for some confirmation of congestion on the network, or else helpful ways I can debug this further at home.
I'm on a 250M / 15M plan. Normally I see a solid 250+ Mbps down. Tonight I'm seeing the following speed test values:
- 6 Mbps @ http://md.speedtest.rcn.net/
- 10-30 Mbps @ https://fast.com/
I use wired LAN only. I have my own modem and router.
WAN -> Motorola SB6120 -> Asus RT-N66U -> client (desktop, chromecast ultra)
I've restarted my modem and router, to no avail.
