View Full Version : How does the HR20 know if it should connect with a Static IP or with DHCP?

Does it just try static first and then switch to DHCP if it can't connect with the static settings specified in the advanced network settings screen?

It automatically does DHCP only, I think.
If you want to configure static you need to go to advanced screen and choose the IP address.

The info&test screen says if it is configured for static IP.

It will default to DHCP and only change to static if you manually tell it to do so.

It always attempts DHCP when you select regular SETUP. To use a STATIC address, you need to go to "ADVANCED" setup and manually key in the IP address information. /steve

Change to static how? There is no way to select between static and DHCP in the setup screens.

If by "regular" setup you mean selecting "reset to defaults", that always sets up a static IP address in the advanced settings, which is why I suspect that it might first try the static IP address and then switch to DHCP if it fails.

The best option would be address reservation in your router, if it supports that function (most do). Basically you tell your router that MAC address xx:xx:xx:xx:xx:xx (MAC of your HR20) is always assigned ip address 192.168.xxx.xxx (IP address you want assigned.)

If you set this up in your router you will not need to do anything to the HR20. Although I really can't think of any reason the HR20 would need a static ip unless you are forwarding ports or setting it in the DMZ for some reason.

IOW, "DHCP" is not a substitute for the address, it's simply a client/server application that asks the router to assign your unit the next available LAN address it can find, instead of asking you to manually (statically) assign one. It actually an acronym for "Dynamic Host Configuration Protocol". /steve
