7 Things To Know About Wi‑Fi Extenders

If Wi‑Fi routers can’t cover your whole house or you want internet connection on different floors then Wi‑Fi extenders are one of the best options available. As these can easily increase the router’s coverage area and also maintain the same speed, so Wi‑Fi users with bigger or uncommon house structures use them quite often.

So, in this post, I come up with 7 interesting things that users ask frequently about Wi‑Fi extenders. If you have one already, I am sure these tips will help you in using it more efficiently. But if you are planning to buy an extender, then also you apply this knowledge in selecting the perfect one.

1. Can Wi‑Fi Extenders Go Through Walls?

Wi‑Fi extenders can go through walls easily, they are just like Wi‑Fi routers. Just they consume the signals of the existing Wi‑Fi router, amplify it and increase its range maintaining the same strength rather than provide their own.

That’s why if a user installed it properly, then it can provide the same internet speed and connectivity. Now, signals from these Wi‑Fi extenders can pass through walls, but it is also true that if you install it on a very closed space then the signal strength also reduces a bit.

That’s why these Wi‑Fi extenders can easily cover two-three rooms, but if the device is too far away, you might not get a good or stable internet connection.

Also, depending upon the Wi‑Fi extender’s quality, their range and performance vary, so don’t get surprised if a premium router provides faster internet connection and also covers more area than normal ones.

2. Can Wi‑Fi Extenders Use Ethernet?

Most of the Wi‑Fi extenders do come with ethernet ports but for running wirelessly they don’t need an ethernet cable. As wireless devices can connect wirelessly with the extender, so the user only needs ethernet, when they have to connect a wired device with the extender.

After purchasing an extender you can’t directly use it, first, you have to sync it with the router. If you are purchasing the latest Wi‑Fi extender, just place it in the range of your router, power it on and after that, it will automatically detect the router.

Then you can set up to use that router’s signal and boost it from App (if your Wi‑Fi extender brand has one), through the official website, or any other method mentioned in the manual.

After setting it up, every time you turn it on, it will automatically do its job and extend the range of signals. So, it is quite unlikely you ever use the ethernet port unless you are using any wired device. 

3. Do Wi‑Fi Extenders Work With Hotspots?

Wi‑Fi extenders work with mobile hotspots and can increase their range but using them for the mobile hotspots is nothing more than a waste of money and time. Unless you have a spare extender or the router is not working, then you can use it.

But keep in mind, if the Wi‑Fi extender you are using is not that good, it can decrease the speed of the internet. As we know mobile hotspot is already very slow and if you use an extender on the top of it, more likely you will see performance decrease than increase.

So, although it is possible to use Wi‑Fi extenders with hotspots, but not recommended at all.

4. Do Wi‑Fi Extenders Work With Any Router?

The latest extenders (not more than 1-2 years old) mostly support all the Wi‑Fi routers and their versions. To check it before buying, the user has to check which Wi‑Fi version the router supports and match it with the extender.

Also, if an extender supports the latest version of Wi‑Fi then it will also support the older ones. Just check the Wi‑Fi version and you are good to go.

Overall, if you have a latest router and Wi‑Fi extender, then they can work with each other. Also, you can directly chat or contact the consumer support of the Wi‑Fi extenders brand asking if it supports that specific router you have or not.

5. Can Wi‑Fi Extender Interfere With Router?

Wi‑Fi extenders consume the Wi‑Fi router’s signals and boost its range or coverage area, that’s why users can get the same internet speed and it can cover more area that a router can’t reach on its own.

So, the Wi‑Fi extenders don’t interface with the routers, but it is possible to get low speed, unstable internet connection in the area covered by the extender if the extender is not good.

Otherwise, extenders just work as a part of the router to increase the coverage area and if you are using a good router with a good extender, you will not face any issues like that.

6. Can Wi‑Fi Extenders Have the Same SSID?

It is possible to have the same SSID in both the extender and router. SSID (service set number) refreshes nothing but the Wi‑Fi/network name. And it is possible to change the SSID or keep it the same if some Wi‑Fi extenders.

While some other extenders select one of their own (you can’t change it afterward). Most of the new Wi‑Fi extender models support changing their SSID and names, keeping it the same, but most of the older ones don’t support them.

7. Single Band Vs Dual Band Wi‑Fi Extender:

A single band Wi‑Fi extender only supports one wireless signal at a time but a dual-band extender can emit two wireless signals at the same time. Also, single band extenders only support 2.4GHz Wi‑Fi while with dual band extenders you can get the advantage of both 2.4GHz and 5GHz.

As most of the routers do come with 5GHz wireless connectivity, so if you want to get the same speed with extender as your router gives, then you have to get one that supports the same speed too.

In this case, dual band or tri-band extender will be the best according to your router’s capabilities.
