Why is Xfinity blocking access to the spectrum analyzers?
Copied from a reddit discussion on the unofficial Comcast page. Could not get a definite answer.
Recently discovered that port 8080 buy doing a port scan of the modems log in IP that Comcast is blocking the analyzer by http proxy.
Why are they blocking this? It wasn't enough that they told modem manufacturers to not display unerrored codewords. Now we can see the analyzers now.
There was a short window where I could access it, where I would disconnect the coax cable from the wall plate. Then allow the modem to lose connection, after that I could see it for a few seconds. Before the modem downloaded the configuration file.
There was a log in page to get to it as well.
Does Netgear use any services on port 8080 with their modems?

It's accessible for me on my CM3000 with Sparklight:
I wonder why Xfinity blocks it? However I have seen some people reports that they can see it with an Arris SB8200 modem.
I tested this with my old Netgear CM1000 and its blocked on it as well.
Post up the cable connections data page then the Event Logs data page so we can see what maybe happening there.
How are you trying to access the spectrum analyzer web page?
Tried different browsers?Was told the the analyzer is supported by your ISP. Supposed to be there.
