Need to help to determine if a new modem is needed as told by Comcast Support.
In the pic, Two lower blue lights are flashing. The internet light is off. The top green lights are steady.
Located Florida. 50/10 Tier. Speed tests were a consistent 57/11 at speedtest.net when it was working. Two weeks before promo prices expire.
Yesterday I got an alert from my network drive that my internet went down. It has not come back up yet.
Visual check outside shows nothing out of the ordinary, like fresh cut areas, cables appear to be good.
The route from the sidewalk goes to a grounding connector, from there to a splitter. One side to the TV and the other side to the modem. I noticed the TV cannot get premium channels, but locals were fine.
I powered off/on the modem and connected my computer directly to the modem. I can connect to the modem fine, but no internet. I left it off overnight so it would forget the mac of the router, which is now bypassed. In the morning powered up the modem and connected directly to the computer, no go.
Bypassed the splitter and connected directly to the cable box, hdmi out to TV. Premium channels were scrambled and blocky like poor signal. Rebooted cable box. After a few minutes able to get premium channels and local channels. The suggestion was that the splitter was bad. Connected the modem directly to the splitter. The modem signals are:
Channel ID 15
Frequency 741000000 Hz
Signal to Noise Ratio 31 dB
Downstream Modulation QAM256
Power Level -18 dBmV

If a modem was bad, would the downstream show out of spec? Thanks for any insight.
