6 Tips for Troubleshooting Wifi at Home

6 Tips for Troubleshooting Wifi at Home

Using Wifi is considered more flexible than personal cellular data. This is because Wifi offers unlimited internet connections so that users can freely browse the internet, from surfing between social media, or downloading applications.

But what if the Wifi network turns out to be slow?



Wifi does offer unlimited internet, but often users also find the speed slow or slow. This is very likely to happen, especially if you use them simultaneously at the same time.

Not only that, various problems can interfere with your Wifi internet speed. To get around that, let’s look at the following tips for overcoming WiFi problems in your home:

1. Early Problem Analysis

At this stage, you need to identify the specific cause of the problem. Is it the Wi-Fi signal that has the problem? Or maybe something else, like your ISP’s slow connection speed?

Start with a speed checker such as Speedtest.net or nPerf.com. If you get good data transmission speeds near the router, but bad in the kitchen, then, as the admin folks have said, the problem is on your side. If so, it is time for another point of view – analyzing your Wi-Fi network.



Many applications that determine the signal strength of Wi-Fi networks are available for all mobile and desktop platforms. Just type “wifi analyzer” in any search engine or app store, and you will see a large selection. Choose one that visualizes the results to help you compare perspectives.

When choosing an application, follow the general precautions, first make sure the application does not require access to your contacts or messages, then perform a security scan, for example with Kaspersky Security Cloud.

2. Do the first try

Next, try experimenting with the position of the router and the angles of its antennae to increase the range. This is the simplest method, requiring no extra time, money, or special skills. For example, if your router is located in an alcove or some kind of cabinet, especially one made of metal, try moving it elsewhere. Metal isn’t Wi-Fi’s best friend, and neither is reinforced concrete.

The position of the router antenna also makes a big difference. Google “router radiation pattern” for the theory. Coming back to the practical level, it is worth remembering that in most cases the best position for the router antenna is an upright position. That way, your Wi-Fi router will get the best horizontal coverage.

Also, check to see if anything is blocking. The refrigerator, for example, is the enemy of radio waves, and not one of those items that can be easily moved. On the other hand, microwave or baby monitors – which operate at 2.4 GHz and compete for the same frequencies that routers use.

3. Configure Channels

Wi-Fi operates in a series of narrow bands, called channels, of the radio spectrum. Several channels are available, although the number of devices wishing to use them may be large. Therefore, the most popular band (2.4 GHz) can be clogged with noise from neighboring networks and other devices.

On each reboot or at the scheduled time, the router selects the channel that is the least interference-free. This is comparable to the way the navigation system chooses the route with the least congestion.



Routers usually handle this task on their own quite well, but it’s possible to be given intervention. For example, you can configure your router to automatically search for clogged channels more often, or even set it up manually.

But be careful when doing the latter; Spectrum congestion is very fickle because not only your router but the neighboring router is also constantly and automatically switching channels.

Some routers also allow users to change the Wi-Fi signal strength. Check the router settings to see if it is set to the maximum value and if not, then it can be done.

4. Move to 5 GHz

If your current router doesn’t support the 5-GHz band, you can try upgrading to a more modern version with support for the 802.11ac standard (aka Wi-Fi 5). It’s no longer a luxury; Most affordable models start at around $ 50.

Currently, there’s no need to go for the more advanced 802.11ax (Wi-Fi 6), which may still be quite expensive. Upgrading to Wi-Fi 6 is likely to have a noticeable impact only if you have lots of traffic-hungry Wi-Fi devices at home.



Remember, however, switching to 5 GHz is not the solution. The downside of higher frequencies is that the signal diminishes faster with distance, and the effective coverage in a larger apartment or house can be quite disappointing.

It all depends on what the problem is with your Wi-Fi network. If the 2.4 GHz spectrum you live in is clogged with someone else’s network, and 5 GHz is available, an update is very helpful. But if your 2.4 GHz network can’t reach your kitchen due to distance and lots of reinforced concrete walls, 5 GHz may also not be an option.

5. Use Cables

We’re so used to the convenience of Wi-Fi that we sometimes forget about wired Ethernet, which has been around for a long time but is much better. Connecting via cable is often the easiest and cheapest solution to seemingly no-concurrent Wi-Fi problems.

Using a wired connection can provide two main benefits: First, it can solve problems in a room where Wi-Fi is difficult; second, if you transfer at least a few devices to the cable, the quality of the wireless connection on the other devices tends to improve. Sure, Kaliam can’t connect a smartphone or tablet this way, but it doesn’t matter for desktop computers or smart TVs.

If the cables that run around your house are an eyesore and there’s no easy way to hide them, try a power line adapter that transmits network signals through your power cord. On the downside, the power line equipment becomes unpredictable at times and sometimes refuses to coexist with local power lines, this is an important point to note.

6. Connect the mesh network

Perhaps it is best to stick to a ready-made mesh network kit. Such kits are available from most of the major network equipment manufacturers. They consist of a central router and several additional access points.

The latter are arranged in such a way that the signal reaches the farthest part of the house or apartment. With a mesh system, the coverage area of ​​your Wi-Fi network can be as large as you want – it all depends on the number of additional access points.



In contrast to traditional repeaters, the system is centrally managed (enhancements are usually configured automatically), which saves a lot of time and effort. If you can connect the access point to the router via Ethernet, it will increase the speed and coverage area. Otherwise, don’t worry, the mesh system means nothing if it’s not flexible.

Another important note is fast and smooth roaming. This means that video calls with colleagues will not be interrupted even if your family members take you out of the kitchen to a place covered by a different access point.

High-quality roaming on a smartphone or computer requires support for the 802.11k / r / v family of standards.

The good news is this is no longer a luxury item; for example, Apple mobile devices, starting with the iPhone 6s, support all three standards.

Here are a few more setup tips

For roaming to work properly, your 2.4 GHz and 5 GHz networks must also use the same network name and password combination. As for the Mobility Domain ID/key, there’s no need to be too smart – it’s just a label for linking network segments (some routers even set it up automatically).

Mesh networks, of course, have additional costs, but you don’t have to pay a lot for the best devices. Several manufacturers offer routers that support meshing as standard, so all you have to do is buy extra affordable points if needed.

We don’t recommend experimenting with mixed mesh equipment from different vendors, so consider possible expansion when choosing a future system.
