RAX40 Router unable to assign a reserved IP to some devices (MACs)
Hello, My router normally assigned IP dynamically via its dhcp server. But, in order to keep track of my devices more consistently, I decided to assign specific IP addresses to specific devices (MAC...
Salt that sequence away, "once I rebooted the router a second time..." you will use that again in the future.
You had me shaking my head when you started off a sentence with "The first hundred devices..."
It is a good idea to keep a spreadsheet with your device names, IP addresses, and MAC addresses.
Please mark this as resolved so others can benefit from the discussion.
Thoughts to consider:
The discussion is about IPv4 addresses, not IPv6.
Make sure your new chosen IP address is within the range you established in the LAN setup for your DHCP server. There is a range start and stop point configured in the router.
Different devices behave differently, but usually you cannot change an IP once assigned with the devices powered on and the connection made. To change that IP address, you would need to power down (pull the power cord) for the device to break the connection. Then make the changes in your router and power it down (pull the power cord). You might have to power down and restart your router before you can make the IP address assignment. When you start them back up, power up and let the router stabilize first before powering up the device.
Many devices have multiple MAC addresses. My smart TV has one for the 2.4 GHz radio, one for the 5 GHz radio, and one for the Ethernet port.
