We've recently had fibre installed along with Spark's "Smart Modem".

Only issue so far is that, because out networked printer is only powered up when needed, it gets a new IP addressed assigned every time it boots up. Mildly annoying when you go to print & things just hold in the queue.

Not a problem on old ADSL modem, but no obvious on Spark's modem admin page as to where to set a fixed address for a given device.

Any clues, or step-by-step guide, on how to do this for this modem?

Thanks in advance.

I'd go the other way and set the fixed IP on the printer itself - just use one out of the DHCP pool range which I believe is 192.168.1.64-192.168.1.253 by default

So you'd pick something like

192.168.1.10

Subnet 255.255.255.0

Gateway 192.168.1.254

DNS 192.168.1.254

(if asked for other info)

I would never assign static IP addresses by setting static DHCP leases in a router - IMHO the only approach that should ever be taken is to follow the setup above which is configure static IP's directly in the device itself.

Does the Spark router really assign a different IP address every time a device does a DHCP request? My router just gives my printer back it's last assigned address (assuming it hasn't been assigned elsewhere) even if I haven't turned it on in weeks.

As above a static IP address would be a good solution.

would depend on how long the lease time is.

my parents have a HG659 (older spark router) and almost daily i would receive a new IP when i would turn up there.

Would not using a dns name for printer solve all your problems. That way you could just set devices to print to the DNS name instead of an IP address?

Some devices cannot be configured manually with a static IP address (I'm looking at you WD My Cloud Home), so here's how to reserve an IP address for a particular MAC address in the Smart Modem's DHCP config:
