Can't connect to wifi on different subnets with pumps
Posted on 2012-09-18
We have a bunch of CareFusion Alaris pumps that we need to connect to our WIFI units (Meraki MR16). We have 3 subnets in our facility.
192.168.50.xxx (main switch, dns/dhcp resides on this subnet.
192.168.51.xxx first floor
192.168.53.xxx second floor
These pumps will connect to the wifi on the 50.xxx subnet but will not connect to the wifi’s on the 51.xxx or the 53.xxx subnet. We statically assigned them an ip and then they will connect but these will be roaming from floor to floor so that won’t work in production. We don’t have this issue with any other devices using the wifi ie.. laptops, iphones, ipads.
So if I plug my POE access point into a port running 50.xxx the pump grabs an ip from dhcp and life is good. When I move that access point to 51.xxx or 53.xxx and turn the pump on it does show the wifi signal strength but never receives an ip address. The display on the pump shows Associated for 1 minute than dissociated flashes than back to associated.
