Eliminate connection errors, interruptions, etc.
WLAN networks may have repeated problems-short range or strong signal strength, interruption or very slow Internet speed. In this guide, you will find useful tips and tricks to easily eliminate the most common WLAN errors.

More tips for solving network problems
Now, we connect our houses almost completely via WLAN. This is very comfortable and can save the wiring of our entire apartment or house. Of course, the main advantage is that you can use various devices to access the Internet wirelessly. Who wants to connect the LAN cable to their smartphone through an adapter? However, wireless connections [including WLAN] are more susceptible to interference or other effects.
These may be simple physical laws, such as very thick concrete walls, large plants, or just suboptimal placement of router planers. However, there are also many potential problem areas in the hardware and software fields, which ultimately lead to poorly functioning WLAN networks. Therefore, you should investigate the cause of wireless network problems at various levels. We will provide advice and actions around you and help you. Below we list the most common and annoying WiFi problems and explain how to best solve them.
prompt: Read tips about WiFi reception, range and speed. Handling various physical problems there may sometimes trigger connection problems. The wrong location of the router may also be the cause of poor WiFi reception. We deal with problems at the protocol level in the guide to eliminating network problems, namely IP assignment, DHCP or DNS.
Small WiFi range
Do you see a bad connection on your smartphone or laptop or the connection keeps disconnecting?
Objects, walls, etc. will reduce the propagation speed of radio waves. You can expand the range by better placing routers. In our article "WLAN: The Right Location of the Router", you will find everything you need to know. "Antenna alignment" can greatly increase the range.
Cancel: Change WLAN frequency
For example, if you are stuck in a 2.4 Ghz network because you live in a high-rise building with twenty routers nearby, sometimes it only helps to switch to a 5 GHz network.
In addition to the 2.4 GHz frequency range, there is another area in the 5 GHz network where the reason for the lower frequency is simple-simply because fewer devices in this range send and receive radio waves. If you are struggling with abortion, try changing the frequency.
Cancel: Change Wi-Fi channel
Radio networks may interfere with each other-the result is reduced reception. This is a problem, especially in the 2.4 GHz band, because most routers and devices transmit here.
Routers such as Fritz boxes automatically find the best available channel. If you have to readjust manually, please select channel 1, 6 or 11 as the WLAN setting in the 2.4 GHz range. In addition, we will show you the right tools that you can use to “find the source of WLAN interference quickly and easily”.
Cannot find WLAN name SSID
If the name of the radio network is unknown or the display on the smartphone is blocked, you cannot contact it. As a result, the connection to the WLAN fails.
Therefore, in the router settings, if there is a check mark, you must disable the "hide SSID" display. SSID stands for Service Set Identifier and represents the name of the WLAN. Your Wi-Fi should now be visible again.
WiFi problem: wrong power option
Some of the Wi-Fi problems are due to the power saving options of the Microsoft operating system. If the problem occurs again, you should check it.
Navigate through the following path: "System Settings"> "Hardware and Sound"> "Change Energy Saving Settings"> "Change Advanced Energy Saving Settings". Click "Wireless Settings"> "Energy Saver" and select the option "High Performance".
No network adapter found under Windows
You have updated the operating system, but the computer cannot connect to the WLAN. The reason may be lack of driver support.
To check, open the device manager in the settings of Windows 10. If you find an exclamation point under the "Network adapter" entry in the WLAN hardware, there is a problem with the driver. Install this program and your adapter should work.
IP address is not available
The IP address is the house number of each device used for travel on the Internet. It is important to have an IP address, otherwise the data packet will not reach the correct location. If your device does not have an IP address, you will not be able to access the Internet.
Incorrect router settings may be the reason that the IP address does not exist. It makes sense to use DHCP, which stands for Dynamic Host Configuration Protocol. This service ensures that if a WLAN device dials successfully, it will automatically be assigned an IP address in the network.
Despite the WLAN, there is still no Internet connection under Windows 10.
Under Windows 10, despite a valid WLAN connection, you still cannot access the Internet.
In our excellent guide to Windows 10, you will find solutions that can make your Internet connection restart and work.
Forgot WiFi password
You have forgotten the WiFi password. How do you go online?
If you have not changed your WiFi password, you will usually find it on the sticker on the bottom or back of the device. You can also call the web interface of the router. Use the device password [which you can also find on the label] to dial, and then you can view the password. Having said that, there are other ways to find the password.
No WiFi network found
Your Wi-Fi network will not be displayed on your computer, smartphone or tablet.
The router usually has a physical WLAN button for turning the wireless network on or off. When cleaning or finishing, the buttons may be accidentally pressed. Therefore, check whether the WLAN indicator is lit on the router.
Can't connect to WiFi
Even if you enter the correct password, you cannot connect to the WiFi network. The problem may be the MAC filter.
On the router's web interface, a so-called MAC filter can be used to protect the WLAN network. Here, you can specify which device is allowed to join the network. If this feature is active in the router, external devices or new devices will not be able to dial in. Check if this function is activated. You can turn it off or add devices to connect.
