I have a Brother network printer Ethernet connected to a 5031NV RG. The printers own WiFi Interface is disabled. Two of my Windows 10 clients can ping and print to it wirelessly as I intend. A third Windows 10 client can neither ping nor print to it unless physically connected to one of the 5031's other Ethernet ports. Web access on that third client is normal and it can ping the other two wireless clients wirelessly, just not that printer unless that client is physically connected. I have eliminated the client's firewall as a cause.
If the RG's wireless interface is disabled and replaced by an Airport Extreme in bridge mode behind the RG, then all three wireless clients can access the printer at the same three IPs assigned by RG. I'd rather not use the Airport, however, as it causes over two minute delays in DNS lookups from the RG after a client connects through it.
Can someone point me to something in the 5031's configuration that would block only one wireless client and only block it wirelessly?
