I have a Ubee cable modem (DOCSIS 3.0) which also serves as a wired/wireless router and DHCP server. I have devices which are on the LAN and receiving addresses from the Ubee that I can't ping from other devices also on the LAN. Example:

• Computer A (static IP 192.168.0.50 wired connection)

• Computer B (DHCP IP 192.168.0.83 wireless connection)

• Computer C (static IP 192.168.0.203 wireless connection)

• Ubee (static IP 192.168.0.1)

• Computer A can ping Ubee and Computer C (Can't ping B)

• Computer C Can ping Computers A and B and Ubee

• Ubee can ping B and C, but not A which is wired to the Ubee and shows up on the client list

(Computer B is a microcontroller and is working fine with MQTT) Hope I have explained this well enough. It's driving me crazy. Is it something about the Ubee, something dumb I'm doing? Thanks for any help. Bob
