ARRIS TM602G - web admin page only accessible during boot?
This isn't really a problem, more of a puzzle - the administrative webpage at 192.168.100.1 for my comcast arris modem is only available during the 30 seconds it takes to boot. When the modem is fully online, the ip is unresponsive and will always time out. If I manually reset the modem, I can get through that page briefly, until the service cycles back up and then the page times out again.
My service is very stable, I am just curious as to why this would be happening - some sort of administrative lockout on purpose?
Mostlikey your in a IPv6 service area and your DOCSIS side is in IPv6. The Arris 402,502, and 602 have this bug in it. If you PM me your public IPv4 address I can confirm this for you, but most-likely this is the case.
