That part isn't necessarily odd. You can't have two different boxes handing out addresses in the same network range; that's a real recipe for confusion. So I'm assuming that you have two separate networks here (masked with 255.255.255.0) which are routed together?
If you don't want separate networks for security reasons the more usual arrangement is to disable the IP allocation server (DHCP) on one of the boxes. Whether that's trivial to do or not depends on your network configuration: are the Orange and Ubiquity boxes wired together? are both acting as WiFi access points? if your laptop ends up on one WiFi network and your printer is on the other one then that could cause issues depending on how the routing is configured between them. I would consider trying to get all your devices onto the same network; it makes troubleshooting this sort of issue easier. Also disabling the WiFi on the Orange box might help if it isn't already. Ubiquity boxes are quite clever at managing WiFi coverage but a second WiFi network might confuse it.
Configuring mobile devices to automatically switch to a stronger WiFi signal on the same network is a black art I've never learnt. My devices stubbornly hang on to their connection as it fades even when I move into a room with a 100% signal on a different AP.
