Wired (Ethernet) networking

I have the xFi Advanced Gateway it only has 2 ethernet ports, I need 6. What do I need to use to expand a switch or just a plain hub?

 

Thank you.

Use an ethernet *switch*, not a dumb "hub".

Do they even still make hubs?

For those wondering what the difference is: A hub repeats any data to ALL other ports. A switch keeps track of the MAC address and only copies data between the source and destination ports. A hubs total max speed is the basic Ethernet spec. A switch could, in theory, support greater since data is only moving from one port to another. That would assume multiple different computers talking to multiple other computers.

My point to @RobertWy was made. Use correct terminology.

People here muddying the waters 🤦🏻‍♂️
This is not complex or confusing.

All you need is a network switch e.g. Netgear Gs308.

Plug the switch into your gateway and everything you need extra Ethernet Ports for into to the switch.

Noted.


I see that you edited your post. Thanks for providing the clarification.

Netgear, Linksys, Tp-Link, Cisco, and others still manufacture Hubs.

Gigabit?   How would that work?  I thought part of the gigabit spec was negotiating speed, and an hub with mixed speed ports would have a serious problem forwarding everything everywhere.

“ The distinction between the cheap and expensive devices these days is whether the switch is 'smart', allowing configuration of VLANSs, monitor ports, etc.“

Those are “managed switches”. Not “smart switches”.

“ You will want a gigabit switch.”
The Netgear GS308 in the example I gave is a gigabit Ethernet switch.

Sure do.

You will want a gigabit switch.  I don't think anyone makes hubs anymore (hubs forward all packets to all ports, switches learn the destination devices).   The distinction between the cheap and expensive devices these days is whether the switch is 'smart', allowing configuration of VLANSs, monitor ports, etc.  Most people do not need such features in a home network (you wouldn't be asking questions here if you needed them), so the low cost switches are fine.

You are conflating two separate comments and completely misunderstanding Gigabit Ethernet networking.

@RobertWy TEG-S82G is a good switch.

Thank you.  I have two, one downstream from the other, which is connected to my XB6 in Bridge Mode.


If the XB6 was truly in bridge mode, there would be only one public IPaddress available. How could the switch  work for multiple devices ?
