Installing a new router but experiencing no internet connection.
8.8.8.8 and 8.8.4.4 are Google DNS servers. Using 1.1.1.1 comes from Cloudflare DNS. Saying it works now usually means you made a change or stopped using the old setup, and it should work without issues. Switching IP addresses on your internal network can help devices reconnect smoothly.
In reality, you didn’t have to duplicate the address directly. You should have simply turned off and on the modem. The reason it functioned after the Mac update is that it was using the same external IP address it had been leasing. So if you just restarted the modem, the most likely outcome would have been a shift in your external dynamic IP, achieving the same result as cloning the MAC address. If you ever choose to use that older router again, you’ll need to update its MAC address on the new device.
Older systems often need re-registration whenever a new computer or router is added, which is pretty much outdated. In most scenarios you're correct—about 99%. Beyond that, certain routers like TP-Link can reduce performance on high-speed links if MAC addresses are duplicated. This usually affects speeds above 400 Mbits.
I'm still adjusting a few settings but I'm sticking with the two Cloudflare options you mentioned. I prefer the 192.168.1.xxx range and I might need to switch to another network with similar IP ranges later.
