5 Effective Tips For Improving WiFi Signal & Speed At Home

Unstable and slow internet connection can be frustrating. Surely, you can move your router around and try various fixes for your internet access. But the fact remains this – Your internet connection is only as fast as your WiFi router’s standard.

A WiFi standard is a network protocol that determines networks work in terms of data transfer rate and transmission frequency. The IEEE 802.11ac (WiFi 5) used to be the most popular WiFi standard because of its dual-band support of 2.4 GHz and 5 GHz, as well as backward connectivity with its predecessors. Since 2020, the 802.11ax (WiFi 6) is the more recognised standard, offering faster data transfer speeds, and reduced power consumption.

WiFi standards play a crucial role in your connection speed and range. If your device uses an older one, then an upgrade may be necessary for the best experience. We explain how you can do that in this article along with other tips for improving WiFi signal.

5 tips for improving WiFi signal and boosting connection speed

1. Upgrade your router

If fast internet connection is important to you, you will need a WiFi 6 router. They can reach an estimated speed of 10Gbps, where WiFi 5 routers only reach 3.5Gbps. More importantly, WiFi 6 router’s have more spatial streams than its predecessors, which is something you should always look at before buying a router. 

WiFi routers are generally half duplex in nature, which means they can send or receive data, but never both at the same time. Your smartphone is an example of a full duplex device since you can speak and listen all together. Because your router is a half duplex device, you’re going to experience a delay in speed when sending or receiving heavy data. To compensate for this problem, most modern WiFi router’s support spatial streaming.

Spatial streaming is the connection your router makes with an endpoint that allows it to divide signals and send or receive them at the same time. In modern times, devices use Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) technology to send and receive signals simultaneously, unlike in the past where transmitters and receivers had only one antenna. MU-MIMO helps routers separate signals to avoid collisions that can cause co-channel interference, and achieve faster transfers. Co-channel interference occurs when there are many devices transmitting signals within the same area, or using the sameWiFi channels.

The number of spatial streams routers support is usually indicated with multiplications. For example, 4×4 or 5×5. WiFi 5 supports four streams (4×4), while WiFi 6 routers offer eight streams (8×8).

  • The first number represents the amount of antennas your router uses to transmit signals.
  • The second number represents how many spatial streams your router can receive at a time.

When in doubt, a useful rule of thumb is to target more antennas. The more of them your router, the more sensitive it will be to WiFi signals, as well as faster in uploading and downloading data. Since Mesh routers don’t have physical antennas, you’re going to have a hard time knowing your spatial streams on sight. We suggest finding the information on product information pages of online stores, or your router’s product box and manual. If you don’t find the information, contact the manufacturer.


2. Change your Wi-Fi frequency band & channel

Choosing the right WiFi frequency band and a low-interference channel can significantly improve your network coverage. Smart routers do the selection for you, but your connection could be affected if your neighbors are on the same channel as you. You may need to configure the settings yourself from your router’s website.

The most modern WiFi routers are dual-band. They can support both 2.4GHz and 5GHz bands allowing you to switch between both whenever you experience network issues. Both bands are not the same as the 5G or 2G networks.

The 2.4GHz band can cover a large area of up to 300 feet, but will do so at slow speed. It’s not the best option if you live in a crowded neighborhood. Because the router’s band reaches far, you’re going to experience more interference from competing signals around you. On the other hand, the 5GHz band travels at a fast speed, and is less vulnerable to interference. However, it has a short range. You can only use it within an indoor range of 90 feet. 

Furthermore, both frequency bands are divided into channels. WiFi channels are like smaller bands through which your WiFi network transmits and receives information. The 2.4GHz band has a total bandwidth of 100 MHz and 14 channels. Each channel is 20 MHz wide, but 11 of them have just 5 MHz space in between. Since all the channels are squeezed together within the total bandwidth, they overlap. Channel overlapping occurs when WiFi channels bleed or blend into each other. For example, if you’re on channel 4 and your neighbor is on channel 5, you would experience co-channel interference.

Only three channels in the 2.4GHz band are non-overlapping, which are channels 1, 6, and 11. On the other hand, the 5GHz band has a bandwidth range of 160 MHz and 45 channels, 25 of which are non-overlapping. Each channel is 20 MHz wide with 20 MHz space in between. Nevertheless, it’s important to note that not all channels are available in every country and not all devices may support them. 


3. Update your router firmware

The firmware is the software that comes out of the box with your router. Just like your Windows PC, Android, and iOS devices, router manufacturers frequently release firmware updates for improved performance and security enhancement. Some routers may automatically check for updates and install them for you, while you may need to do it yourself with the router’s native application. 

Typically, searching your router’s IP address with a browser opens the user login page for the product. You should have a default login username and password, which you can find in the product manual or on the device itself, and change when you want. After successfully logging in, you should be able to find your firmware version under the Advanced, Maintenance, Management, or System Tools menu, depending on the layout of the webpage. You can use a WiFi Analyzer app to examine surrounding networks and optimize your network for the best connection. 


4. Position your router centrally

Contrary to popular belief, changing the position of your router doesn’t improve the speed. Your WiFi standard has already predetermined that aspect. Instead, what repositioning does is to stabilize the signal. For example, let’s say you put your router in the kitchen. The device may have a fast speed, but it will be affected by electrical interferences from your refrigerator, microwave, and dishwasher, causing the connection to be unstable. If you put the router in your bedroom, then your overflowing closet or bulky mirror frame may also interfere with the signal. 

Most modern routers transmit signals in a literal circle. So if you want an interference-free connection, you would want to place your device centrally. If you’re not sure where that is, think of any spot in your house that has wide spacing and no furniture or gadgets scattered haphazardly. Let this spot have enough open space and allow for good airflow. Once you’ve found your spot, elevate the router with a table or high shelf because floors can affect WiFi signals. If you don’t have a good spot in your home, then you can create one. Focus on moving objects around, not the router. But if you’ve tried this trick and you still don’t get a favorable result, you should consider buying a WiFi range extender — or just buy a mesh router.


5. Switch to wireless mesh routers

Mesh routers have more speed, stability, and coverage than the traditional routers because of their decentralized design. You can have multiple points-of-access in your home without needing different routers for each room. Instead, what you will have are nodes. Nodes are radio-like devices that come with your mesh router when you first buy it. You can place them around your house to enable you to get a wider network coverage. 

The mesh router acts as the central hub while the nodes bounce off signals around the house so you can access the Internet in whatever room you are. For example, if you leave your bedroom and go to the kitchen, the nodes will reconfigure themselves and automatically switch you to the best optimal connection path. Even better, you can disable one node and it won’t affect the others. 

With traditional routers, you just have a single access point. The further you are away from it, the weaker your connection is especially with multiple people connected. You would need to buy a range extender to improve the connection. If you need help transitioning from traditional routers, our recent post explains which mesh routers are the best to use. 


Conclusion

WiFi standards have already determined the theoretical speeds of your router. But that doesn’t mean you’re stuck with a poor internet connection forever. Repositioning your router and firmware updates are part of the many steps you can take to enjoy stability while connected to the internet. In some cases, a simple reboot could save you all the stress.

Buying a new router may be off your bucket list, but it’s worth considering if no solution seems to be working for you. Preferably, buy products from the same manufacturer. While cross-matching new and old routers doesn’t render the old ones obsolete, same-brand routers have better compatibility. The same goes for mesh router nodes. Overall, we hope you find these tips for improving WiFi signal helpful.
