said by axyoung9022:Individual computer can connect to Bell Giga Hub Gateway then access to Internet. Any computer on Wi-Fi also can communicate to computers on Giga Hub Ethernet. However Computers on Bell Giga Hub Local Wi-Fi Home Network can not communicate each other. Using Windows Command "ARP -a" , MAC Addresses of other computers on Wi-Fi are not listed. So Bell Giga Hub Wi-Fi must have restricted sending MAC addresses to other computers during ARP request, thus it can not work on address resolutions . This is the bug in Bell Giga Hub.
You said Wi-Fi can communicate to ethernet. Then said Bell Giga Hub Local Wi-Fi Home Network cannot.
What is Bell Giga Hub Local Wi-Fi Home Network?
If you are references the Guest wifi you can enable then this is not a bug but by design.
