Please help connecting doser 2.1 SA

[Blakelangley]

Hello. Im hoping I can get some advice to connect this new to me 2.1 SA doser. I downloaded app and tried to connect but I'm not seeing the doser Hotspot available on Samsung or iPhone devices. I also plugged it in the LAN but it does nothing. It doesn't even come up as a connected device in the
Router setup ip page. I'm no tech guru but I'm usually okay with getting these devices connected. This one is giving me a hard time. I have several hp laptops and chrome books but they run chrome os.

Can someone assist me and trying to get this doser online? I'm running a 3 year old jeabo doser and it's been very inconsistent lately and have a high demand reef. I really appreciate any help regarding this! Thanks
