CM600 Modem requesting a DHCP renewal approx. every 4 1/2 hours. Seems too frequent. Is it normal?
Firmware 1.01.14 My Spectrum (ISP) DHCP lease is 1 week, and has been for years. My previous Arris SB6141 modem never requested a renewal prematurely, only when it was time. The CM600 is requesting ...
Thanks FurryE38.
I should have mentioned these other things.
ISP is Spectrum.
Yes, it's been factory reset.
Line quality to/from the modem is great, as verified by me and ISP.
There are no COAX splitters, and the line from the modem to the box outside my house is basically new...they replaced it last year.
I guess you're saying this isn't normal for this modem. My ISP told me that our leases are for 1 week, and they verified how many days left was on the lease when I called them. So, it sounds like a bug in the modem, but I'll have them reprovision it.
Every 4 hours, I get these logs:
DHCP RENEW WARNING - Field invalid in response v4 option (this is OK, many people get this)
DHCP Renew - lease parameters UTC Time Offset modified
DHCP Renew - lease parameters Time Protocol Servers modified
Any update on this issue? I have a CM1100 that is doing the samething. No Splitter, near 0.0 power levels dBmV no other issues other than 4 hour dhcp renewal warning and renews. My ISP spectrum said I needed to factory reset my wireless router because they claim it was doing it but the mac address in the description was for the modem. Either way I did the factory reset and re-entered all my setting but no change.
So is this causing a problem?
