Network extender vs repeater: what are their differences

The first thing we are going to deal with are the causes that can cause our Wi-Fi network to not work well. Then we will see the differences between the network extender and the WiFi repeater, and when we should use one or the other more. Then we will talk about what factors we should look at when buying one and how we should locate them.

Reasons why our Wi-Fi network is not working well and causes

One of the first temptations we can have when our wireless connection is not working well is to buy additional network equipment. That option is usually not a good idea without doing a series of checks. The reason may be because by making a series of changes we may be able to solve the problem and save good money. Also because we make a bad diagnosis and buy the wrong equipment.

In case you don’t know, the great enemy of Wi-Fi is distance and architectural barriers such as walls. If we want to do things well, we should consider before reviewing these points:

  1. If he router is well locatedIn this regard, it must be located in a central place in the home or office. It should also be at a medium height and in a free space (never put in a drawer).
  2. Keep the router away from devices that can produce electromagnetic interference. It is recommended that you stay away from cordless telephone bases, computers, and microwaves.
  3. Test the router channel changeHere, it is convenient to look at the channel of the two or three networks that we have closest to and choose a channel as far away as possible.
  4. Look at the orientation of the router’s exterior antennas. If they are vertically, they favor coverage on the same floor, and if they are horizontal, more is distributed between the upper and lower floors.
  5. Review Wi-Fi band choice. If we are connected far from the router, even if we lose speed, we will gain stability by connecting to the 2.4GHz band. On the other hand, if we are close to the router, the ones that interest us are the 5GHz networks, we gain in speed but as we move away they are less stable. Therefore, sometimes a good choice of band can mitigate or solve our problems.

Another thing to study is whether our router has become outdated. For example, if you only have the 2.4 GHz band it is a clear symptom of it. Our router must at least support the 802.11.ac standard, which is also known as Wi-Fi 5. However, given the drop in prices, it is better to look at one with the Wi-Fi 6 standard or known as 802.11.ax. On the other hand, if in our Wi-Fi network the network extender or a repeater are outdated and do not support the mentioned standards, they can also be the culprits. Therefore, before doing anything, it is necessary to determine if the culprit is the router, the network extender or the repeater.

Differences Between Network Extender and Wi-Fi Repeater

Both have as main mission to provide Wi-Fi coverage of our homes and work centers. However, although in some situations both can perform the same tasks, we will see how one of them is more complete than the other.

The Wi-Fi network extender It will be able to allow us to emit the signal from our WiFi router wherever we place it. In this regard, it should be noted that it is a more complete network equipment and that it can also work as a repeater. As they need to provide the best possible performance, it is quite possible to find network extenders with two, three or four external antennas.

Another feature that differentiates from a repeater is that they always have an Ethernet network port. This port is used for:

  1. Connect via Ethernet network cable to a non-Wi-Fi router, and provide a wireless connection.
  2. Joining a network cable to an outdated Wi-Fi router and outputting a higher quality wireless signal.

On the other hand the WIFI repeater also known as a Wi-Fi booster, it only serves one function. This would consist of collecting the wireless signal it receives and then amplifying it in order to extend the range of that signal. Their everyday mission is usually simply to propagate the wireless signal of a Wi-Fi router.

In summary, the main difference of a repeater with the Wi-Fi network extender is that the latter, in addition to receiving and transmitting the wireless signal from the router, we can also connect it via a network cable to the router to improve its Wi-Fi.

Things to consider when buying networking equipment

After having verified that we have a competent Wi-Fi router that is modern enough for our needs, we will start working. What we have to do is that the network extender or repeater has similar specifications to the router. Thus we must seek that both have:

  1. The same Wi-Fi standard, for example 802.11.ac or WiFi 5.
  2. They support the same bands, in this case at least buy a dual band that supports 2.4 GHz and 5 GHz.
  3. Look at the maximum speed they have.
  4. Know the speed of the Ethernet port on the Network Extender. It would be recommended that they were Gigabit Ethernet. In addition, that the network cable was of the corresponding category in this case minimum Cat 5E although better Cat 6.

The best way to find out the specifications is usually to visit the manufacturers’ websites. Once done, we must compare them so that they are as similar as possible.

Regarding its placement, we must apply the same conditions that we discussed with the router in the first section. Among other things, do not put them in cabinets or near devices that emit interference. Both the network extender and the repeater that we use, only in wireless mode we should not place it too far from the router. If we do it like this, the signal that reaches this equipment will be very weak and we will hardly notice any improvement. The ideal would be to place it in a midpoint between the router and the area where we have little coverage.

So to see where it is best located we could do a speed test if we are using a laptop. So we could get results like these:

Or we can even use an application for our smartphone to check the real speed of our Internet connection.

Lastly, it should be noted that the network extender and repeater require maintenance to keep them safe. This maintenance consists of receiving their corresponding firmware updates and also having a strong password that is changed periodically.
