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.

This 8-port switch has worked great for me:

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

[andyross]

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.

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

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.

“ I don't think anyone makes hubs anymore“

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

I think that they need a switch ! LOL !

“ 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”.

See, https://searchnetworking.techtarget.com/answer/What-is-the-difference-between-a-managed-and-unmanage...

[alienist]

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

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.

“ 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.”

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 IP address available. How could it work for multiple devices ?

I wish I understood your question.  The XB6 provides unique IP addresses to each connected device, I presume, because I can query each device and they have an IP address.

I PRESUME the XB6 sees all my ethernet devices on its single ethernet port.

Well then it's not in bridge mode if it's handing out those private (10.x.x.x) IP addresses.

You are correct; when I was setting up my Orbi I had to turn OFF Bridge Mode and turned OFF Wifi.

My memory forgot what I actually did.

Thank you.

[alienist]

@RobertWy you connected the switch to your xfinity gateway using bridge mode? 🤨

He stated: "I had to turn OFF Bridge Mode"

As you know, bridge mode must be off in order to be able to connect multiple devices to a switch. His gateway is assigning private IP addresses to his LAN.

[alienist]

@EG I know what a router does. Thanks though. 😊

[alienist]

@EG you making this more complicated than it is. Enabling bridge mode disables the WiFi router built in allowing the end user to use an off the shelf Ethernet router and/or WiFi router with his or her xfinity gateway.

@alienist  I also know what a router does. Thanks though. 😊

Enabling bridge mode not only turns off the WiFi, it also disables all routing / DHCP / NAT functions.

Really, LOLLL !!!

I think you are confused. Please re-read this thread... RobertWy stated that he was hanging a switch of of a gateway that was in bridge mode and all devices worked. That because in reality, it was not in bridge mode at all. The DHCP was handing out multiple private IP addresses...

[alienist]

@EG you’re twisting my comment. I said, “WiFi router”. Not WiFi.

[alienist]

@EG “disables all routing” that shouldn’t of needed to of be said because it was self-evident. A “WiFi router” does routing.
