Is WLAN enabled in the Router settings?

If you can’t connect at all via Wi-Fi to your network, you should check whether the wifi function of your router is enabled. Often you have to manually set up a network before other devices can connect wirelessly. The process varies from Router to Router, so don’t be afraid to take a look at the manual of your router. In General, you should make sure to activate the Wi-Fi function, to give your network a unique name and a secure password. We explain how to find a secure password here.

Does the Internet work at all?
You should also make sure that your Router has established a connection to the Internet. To do this, it is best to test whether you can access the Internet with your device via LAN (i.e. via cable). Furthermore, it can be helpful to restart your device as well as the Router. With the Router, you can simply pull the cables, wait a few seconds, and then plug it back in. If your Router generally does not establish a connection to the Internet (neither via LAN nor via WLAN), you should contact your Provider.

Finding the cause
Test whether you can connect to your network with another Wi-Fi-enabled device, such as a mobile phone or Laptop. If the problem with the Wi-Fi connection also occurs here, the cause is probably your Router and you should check your settings or ask your provider for help. However, if the connection works here, the problem is most likely your device. If you want to connect a Laptop to the Wi-Fi, it may be that you have to press a switch on the device itself. Some Laptops have a small switch on the front or side edge that switches the network function on and off. If it is not a Laptop, but a Desktop PC, make sure that it is able to establish a Wi-Fi connection at all. Because many computers are not designed to connect wirelessly.

Driver and other software problems
The Wi-Fi function should be activated on your device. Turn on the corresponding function and the possible Offline or flight mode off. If the Wi-Fi works without problems on other devices, it may be due to faulty settings or driver problems. First of all, you should pay attention to what your operating system gives out for error messages when you try to connect to the network. Often the right hints are given here, how to fix the problem. If this is the case, let your operating system guide you through the troubleshooting first. You can also start the troubleshooting manually by right-clicking on the network icon in the taskbar.

If you still can’t connect, you may have to fix the problem yourself. Outdated or faulty drivers are a common cause. You can try to run an automatic driver update using the device Manager provided by Windows. To do this, simply open your device Manager from the Start menu and search under “network adapter” the device that is responsible for WLAN. Right-click and select “properties”. In the Drivers tab, click Update Drivers. There they are guided through the process. Alternatively, you can install the current device driver from the manufacturer’s side of your Network Module.

Range and other problems
Note that the texture of your environment can have a large influence on the strength and range of the Wi-Fi signal. In the open field, therefore, the range of the signal is much greater than in a large house with thick walls. It can often happen that your devices can no longer connect to the Router a few rooms further. Some electronic devices also cause Signal problems, so they should not be near the router or your device. If you live in a densely populated area, problems can arise because too many users leave their Wi-Fi Signal on the same radio channel. In many routers, you can change the channel manually.
