R7000 internet connection every 30 min - What controls WAN lease time - Router, cable modem, ISP?
What controls WAN lease time - Router, cable modem, ISP ? ISP recently changed all neighborhood IPs, apparently as part of some maintenance. Now I see - Lease Obtained 0 days,1 Hours,0 Minu...
In the WAN, the ISP controls the lease time. The DHCP protocol mandates that a device must request an extension of the lease no later than halfway through the lease, so 30 minutes into a 1 hour lease is expected. Lease extension is supposed to be seamless and should not cause any loss of service.
It's not uncommon for ISPs to use a short lease. IIRC, I once had an ISP that used 5 minute leases! That's kinda short but in the grand scheme of things it's not a big deal. It's only a few packets so it won't impact the speed of your service.
