Connect wifi to rj45

How To Connect A Wireless Router To a Switch (Easy Steps)

It is a slightly more advanced home networking issue, but plenty of users want to know how to connect a Wi-Fi router to a switch, to add more connections to their home network. The process is pretty simple and quick.

1. Get any RJ-45 ethernet/LAN cable
2. Plug one end into any LAN port on the router
3. Plug the other end into any port on the switch
4. The router and switch are now connected.
5. You can then connect additional devices to the switch.

But we’ll go over each step in more detail with pictures so any user can know exactly what to do.

Step #1 – Plug a Network Cable Into A Router LAN Port

The back of a standard home Wi-Fi router usually has 5 ports on it – 4 LAN (local area network) ports and one WAN (wide area network) port.

The WAN port is usually set off a little from the others, and is often colored differently. Depending on whether your router and modem are combined into one, or separate, this port can also sometimes be called the DSL/ADSL/Internet/Broadband/Fiber port. See here for more on the different ports on routers.

Whatever it’s called, DON’T plug the switch into this WAN port; in any case, if your internet is working it should already have a cable plugged into it that goes directly into the phone line/master socket (for combined router-modems) or into the modem via ethernet if they are separate.

Instead, grab a standard RJ-45 ethernet/LAN cable and plug in into ANY of the 4 LAN ports (it doesn’t matter which).

Step #2 – Plug the Other End Into A Switch Port

There’s no need to differentiate between any of the ports on the switch as there is on a router, because all the ports on a switch are effectively LAN ports, since switches are local network devices only and can’t communicate between networks as routers can.

Switches are LAN devices, whereas routers are both WAN and LAN devices; see our comparison article on switches vs routers for more on this.

Therefore just pick any free port on the back of a switch and plug the other end of your network/LAN cable into it. Your router and switch are now connected!

Step #3 – Plug Additional Devices Into The Switch

Now that your router and switch are connected, you are free to plug additional devices by ethernet cable into the other free ports on the back of the switch.

The switch acts as an intermediary device, between these devices and router, ensuring data gets sent back and forth between the correct devices and the router. It manages data transfer on the home network, using MAC addresses to make sure that the correct data goes to the correct devices, and provides more ethernet ports.

What Is The Point Of Adding a Switch To A Home Network?

We just touched on the main reason why users add switches to home networks – to add more wired ethernet access points to the network; to plug more devices in by network cable if needed.

Remember that most standard Wi-Fi routers only provide 4 ethernet/LAN ports; if you need to plug in any more, you are out of luck on most routers.

Obviously many more devices can connect by Wi-Fi, but this isn’t always the best option for users who need a strong connection and low latency (gamers) or high bandwidth (streamers). Wi-Fi is often slower than ethernet so it’s preferable to go wired when possible.

Therefore switches open up the potential for more than 4 wired LAN connections on the home network if they are needed. See our article on the different options open to you if you’ve run out of ethernet ports on your router, with switches and other alternatives discussed.

Some Key Points on Routers vs Switches on a Home Network

Here are some key differences between switches and routers for home networks, plus some do’s and donts for using them :

• In simple terms a switch is designed to connect devices together within a single local network, whereas a router connects multiple different networks together.
• Switches can be used to extend or strengthen connectivity in local area networks (LANs) such as in homes, whereas routers connect local networks to broader networks such as the wider internet.
• In general only ever connect routers to switches to expand home networks, and never routers to routers unless you are advanced in home networking. Routers to routers can be done but needs some complex setup to work properly.
• You always need a router to use a switch on a home network; you can’t plug a switch into the phone line directly because it won’t work. Switches only forward data and cannot assign IP addresses like routers can.
• Multi-port ethernet switches are readily and cheaply available online; see this article for links to some good ones. Here are 2 quick affiliate links to Amazon:
  • • Click here for the TP Link 5 port Gigabit Desktop Switch.
    • Click here for the Netgear GS108 8 port Gigabit Ethernet Switch.

    I have dish network. To access On Demand requires an internet connection. I have wifi in the house, but the receiver requires a hard line. Is there a way to convert wifi to a RJ 45 connection without using usb to power the adapter?

    You are looking specifically for what they call a wireless bridge. It takes the wireless signal and allows you to connect to it via ethernet (RJ45).
    Several makes and models, I prefer this one:

    Can you connect a pc to a wifi repeater via the RJ45 port? (wired)

    In the new house I’ll be moving into (as a student so no real say on changes within reason) there will be a router in the main area. I don’t fancy running a cable between the two as it will get in the way but I need it to be a wired connection for my pc. so would getting some plug in repeaters be possible and connect my pc to the rj45 port on the repeater or would it be best to get a wifi card for the pc?

    A client-bridge is mostly used on a end device that does not have any other option to get wireless. Game consoles or tv you can’t put PCI cards inside and many have very limited support of USB wireless cards. Some tv you must buy a expensive one from the manufacture.

    For a PC it is a much harder call. You could use a USB device on the PC to get wireless or you could hook the client-bridge to the ethernet port. In most cases there will be almost no difference in the wireless performance when you put the client-bridge device right next to the PC.

    The best example of use of a client-bridge on a pc where it almost always performs better are the question we get on this forum of «how do I share the neighbors internet» In these cases.

    Yep you can get power line adapters eg: http://www.pccasegear.com/index.php?main_page=index&cPath=200_1348

    If all you are trying to do is get a ethernet connection for your PC and do not have a need to extend the actual wireless signal I would avoid actual «repeaters». These send out a second wireless signal (ie the repeated data) that interference with the original signal.

    If you get good signal in the room where the PC is located then something like a USB wireless card is going to be easiest.

    If you want to go with a ethernet connected device you want what is called a client-bridge. Most «repeaters» can also run in this mode but they sell cheaper versions that are used for game consoles or tv that do not have wireless. These many times are called gaming adapters.

    The reason you would want to go with a client-bridge rather than a adapter in your machine is if you get poor signal in your room. It allows you to use the ethernet cable to locate the device closer to the main router where it may get better signal. You can also get devices with directional antenna.

    Still if the signal is not good in your room you may be better off with the above suggestion to use powerline adapters instead.

    RJ45 to wifi adapter?

    I have an IP phone that has an Ethernet connection. I want to put this phone in a room that does not have any cable drops. Does any one know of an adapter that will plug into the Ethernet port and connect to wifi?

    Do you know what adapters your IP Phone supports? For example, we have a client that has an IPitomy phone system and it only supports one wireless adapter. It automatically installs the driver and just works.

    What you are looking for is called a wifi to ethernet bridge

    Linksys WET610N Wireless-N Ethernet Bridge with Dual Band I used a WGA600N gaming bridge for a long time to link my small home lan to my cable modem on the opposite side of my house at the time. shared connection between 2 pc’s, laptop, and 2 game consoles. You pre-program the wifi settings into the bridge, reboot it, and then plug the bridge into the rj45 jack of whatever needs to be mobile.
