To reach a port we must set sail
What FDR said about ships may be true, but for smart home gadgets, you just have to reach to the back of your network router.
Except when you run out of Ethernet switch ports.
Ethernet ports and why you need them
Our home networks use both wired and wireless devices.
A few home networks might be completely wireless, but most likely yours has a mix of both Wi-Fi and wired Ethernet connections.
Wired Ethernet network connections have their own physical port that uses RJ-45 jacks and receptacles.
Each Ethernet port connects to a single device. If you have multiple devices that need to be connected, you will need to have multiple Ethernet ports.
You need one Ethernet port at each end of the connection. Your devices that use Ethernet will have that port – so half the problem is solved.
But the situation at the networking equipment or central side of things, is a bit more complicated.
One, and two, And three…
At first network equipment like routers and Wi-Fi Access Points always had a single Ethernet connection.
You were required to buy a separate Ethernet switch to connect everything together.
Ethernet switches come in all shapes and sizes and with different sets of features. The simplest, or “dumb” switches, are nothing more than signal repeaters.
Ethernet switches might have 2, 4, 8, 16, or more ports and multiple switches can be connected together for more capacity.
If you want to understand more about Ethernet network switches for wired and Wi-Fi networks, no better place than the source. Cisco is a world leader in networking gear and they invented much of the technology used in Ethernet switches.
You want fries with that?
The cost of buying your networking equipment for home and offices has gotten really inexpensive.
As competition has increased, manufacturers have loaded up their gear with lots of extra features and capability.
Nowadays, home networking equipment is usually a single box that does lots of things – cable modem interface, wireless Wi-Fi controller, network firewall and security, network router, Ethernet switch, and more.
It is common to find 4 Ethernet ports on the back of most routers/Wi-Fi boxes supplied by your Internet provider or purchased on your own.
More is better, right?
But you may still find some equipment only has a single port and you’ll have to buy your own Ethernet switch to get more connections.
Competition is good
Fortunately, the cost of Ethernet switches for home use have come way down. You can find many to choose from for as low as $10 for a 4-port device or $20 for 8-ports.
You should Keep in mind that one port is always needed to connect to your existing router or Ethernet switch, so a 4-port model will give you 3 more usable ports.
Five port models like this one are very popular. Using one port for the uplink, or existing connection, you get four available ports for all your additional devices.
Why this matters
Many of us are using mesh Wi-Fi equipment to eliminate dead spots, increase wireless coverage, and maximize speed.
Most of the popular mesh Wi-Fi equipment assumes you aren’t using a lot of wired Ethernet devices.
You may find that many of them have only a single Ethernet port, some even have none! That’s definitely a step backwards.
Nonetheless, have no fear. You can easily add more ports to mesh Wi-Fi access points the same way by buying a separate Ethernet switch for as little as $10.
So here’s the thing – when shopping for mesh Wi-Fi (or really any router/Wi-Fi box), don’t worry too much if they don’t have multiple Ethernet ports.
You want to pay attention to the specs and features that matter and make a difference in how they operate, since now you know you can always add extra ports if you should need them.
Working from home?
As we spend more time in our homes, and those of us with school-age children have our lives filled with online and distance-learning, Ethernet ports are even more important to help relieve congestion on our home networks.
