Arris TG2472G: Assign Static LAN IP

Anyone have any guidance on how to set a static IP for LAN clients?

Trying to navigate the web interface for the Arris router is a complete failure to begin with... trying to poke around to locate correct configuration pages is unsuccessful, as i always seem to get hung up with:  "Your unit is updating, please wait for a moment"

If you know how to better use the interface to get around that waiting issue, i'd be appreciative of that also!
