I have the Arris TM822G eMTA modem, which is attached via Ethernet to my wireless router. (I own the router.)
I have always been able to access the modem's configuration page at 192.168.0.1 but can no longer do so. I can't even ping that address (times out.)
It's not like I have a great need to see my modem's configuration page; it's just that the information it has might be useful in the event I have to troubleshoot a problem with a Comcast technician. I used to be able to access the configuration page and now I cannot. What could be causing this?
(In all other respects, my HSI service is flawless.)
