Switching from 100mbps to Gigabit requires understanding the differences clearly.

Are hubs even produced anymore? I haven’t seen a genuine hub in a long time; most are now essentially switches with far less capability today. It’s hard to locate a network gadget that still relies on the HUB “broadcast” approach. It’s strange if they still manufacture them, since adding an ARP table to a device is now simple enough.
The specifications for Gigabit Ethernet exclude hubs and any setup that creates more than one device in a collision domain. In practice, full-duplex operation has largely disappeared, and most equipment now supports 1Gbps full-duplex using all four cable pairs, though some brands such as Mikrotik offer a non-standard half-duplex version using just two pairs. This configuration delivers roughly 400Mbps effectively, which can be advantageous in situations where running cables is limited.
