Make sure connected devices are operating in half-
duplex mode. The hub is not compatible with devices that
operate in full-duplex mode.
If you suspect that there might be a defective device on
the network, disconnect devices one at a time to isolate
the defective unit on the network.
If the network is extremely busy, you may have to
segment the network with an Ethernet switch such as a
NETGEAR Ethernet switch or to upgrade your network to
