We're seeing something that looks a bit like client separation - a PC can't talk to a printer on the same network (both on wifi, both using the same SSID, both on the same VLAN and same IP network, not necessarily both on the same AP though). How can I check for this on 17.15.1? I'm not really convinced it is this, because *sometimes* we can print. But maybe it's because they are on sometimes on different APs? Any other suggestions about how the network could be the problem would be welcome.
