Are you using dual NAT or your router directly "dial" the ISP through the modem? Is the modem still acting as a router or it is just a modem?
Also why do you want to clone MAC address? Do you think the ISP has a MAC address list that it check in interval to disconnect unknown MAC address?
If you are using dual NAT and want to know where it fail, you can use tracert (or traceroute). Just do one trace while internet is okay to a server in internet like 22.214.171.124 and store the result. Then when you have problem with internet connection, do the same tracert to 126.96.36.199. See which point the trace fails. Is it between your router and modem, or between modem to the ISP or the problem is at the ISP side.
IDK what dual NAT is. It uses a dynamic IP address.
The modem is just a DOCSIS 3.0 modem. I gave my ISP its MAC address, they "provisioned" it with a config file, and it was activated. The ISP probably does prune unregistered MAC addresses.
The tech who tested it (tracert and pinging) said that the modem isn't giving my router an IP address quickly enough when asked. He thought it might be the modem firmware. When I try to reset my connection thru Windows, it tells me the DNS server isn't responding (which hints that it still sees the internet, but can't use it). My old Arris modem has no problems, apart from being old and costing $8.50 per month.
To me, networking is voodoo and all this troubleshooting is like reading entrails. IDK the difference between a MAC address and an IP address or which machine uses which address for what and when. This is all way over my pay grade; I have a degree in English, and none of this is English. What I do know is that I've followed every troubleshooting tip I could find, and I'm still getting disconnects. IDK what cloning a MAC address might do, but it's the last thing I haven't tried, so I'll try it tomorrow before deciding that the modem must be faulty.
