Enhances 5G WiFi
These 5 tricks will improve your WiFi significantly
Table of Contents
If the WiFi is not working properly, it is often comparatively easy to bring about quick improvements. Many WLAN problems lie in the invisible, namely in the wireless network itself, but are easy to correct. We'll show you five simple tips and tricks that will significantly improve your WiFi reception. Only if they don't work should you think about replacing your router.
Tip 1: use 5 GHz instead of 2.4 GHz
Most WLAN networks still transmit on frequencies around 2.4 GHz. But the frequencies are often overloaded. Because not only WLAN networks transmit there. In addition to radio standards such as Bluetooth, there are also a number of proprietary radio networks - including the Sonos multiroom systems, for example. There are up to 13 channels, but only three of them work without overlapping. Then send your neighbors next to you above and below you, that's it with the fast Internet.
Most routers and end devices (such as the AVM FritzBox or Telekom Speedport) support 5 GHz in addition to the 2.4 GHz band. And this is our first of the WLAN tips: You should set up these frequencies and operate them parallel to your existing network. If you want to make sure that, for example, your laptop only uses the 5 GHz network, you should give the WLAN its own name. Otherwise the computer may automatically book itself back into the 2.4 GHz network. Normally, however, you should give both networks the same name and password.
But be careful: the range of 5 GHz is less than that of 2.4 GHz.
Tip 2: optimize the channel
If your computer or router cannot have a 5 GHz network, you may still be able to outsmart the networks of your neighbors. With smartphone apps you can find out which WiFi channels are being used by your neighbors and you can also see your own network.
It becomes particularly sporty for fast Internet when many networks transmit on one channel at the same time. Because even if no data is being transmitted, so-called beacons are still sent to identify the networks.
The FritzBox routers from AVM, for example, show you whether data is flowing on a channel. You can also see the load for the current channels you have set - but only at the location of the router. It may be that other networks are transmitting again at your workplace. AVM recommends using the "Auto Channel" setting whenever possible. At least with the FritzBox routers, it also evaluates how busy a channel is.
Tip 3: optimize the router space
Where is your router located? Is it on one side of your apartment and you are currently working on the other side of the apartment? Is your router clearly visible on a shelf, if possible a little higher? Or did you squeeze it in a box or behind a cupboard because you don't want it to be visible?
Basically, your wireless router should be as central as possible in your apartment. Because the radio waves spread out in a circle. If the router is on the wall of the apartment, you are giving away half of the power. If you have squeezed the router behind a cabinet, the cabinet dampens the radio waves for the first few centimeters on the way to you. If the router is on a cupboard, the reception in the whole apartment should improve. The frequency bands used are - unlike radio frequencies, for example - quite sensitive as soon as objects block the direct connection. Other electronic devices are also critical, especially when they transmit with Bluetooth. Microwaves also interfere with the WLAN.
Tip 4: rule out interference
WiFi tip 4 is closely related to the first of our WiFi tips. The 2.4 GHz frequencies that most routers use are outlawed in terms of radio technology. They can be used for almost any type of radio link. For example, Bluetooth transmits on the frequencies. But radio links for video transmission, radio thermometers and wireless cameras also use the frequencies. In addition, microwaves sometimes emit interference in this frequency range.
So if, for example, your WiFi is always causing problems when you listen to music through Bluetooth headphones or the microwave is running, then you have radio interference. A channel change can also help here. Incidentally, there are also corresponding interferers in the 5 GHz range.
Tip 5: use mesh networks
If all of these WiFi tips don't help, all you have to do is upgrade. In the end, only several WLAN access points help, especially in large apartments or new apartments with reinforced concrete walls or several floors and underfloor heating.
In the past, this was solved using pure repeaters, which were technically problematic because they slowed down the WiFi speed. Switching between access points was also not always easy. Today there are WiFi mesh systems. Ideally, the repeaters also support cross-band repeating in addition to mesh or even have a third WLAN module on board to transfer the data. In the case of AVM, for example, the FritzRepeater 3000 is recommended.
In some cases, a powerline system can also be worthwhile. Here, for example, we tested the devolo Magic system. Powerline transmits data via your power line, but is not always stable depending on the apartment. However, if you cannot lay a network cable and you cannot cover everything with WiFi Mesh, you have almost no alternative.
But be careful: If you have an extremely fast connection with gigabit data rates, all amplifier and WLAN systems will not deliver gigabit data rates. Only with the increasing spread of WiFi 6 in routers but also in end devices will data rates increase via radio
If your WiFi is still significantly slower than you expect, you should familiarize yourself with the WiFi standards used by your router and your end devices. The reason: Router manufacturers often advertise significantly higher data rates than the devices can deliver in practice as useful value.
