2.4 or 5 GHz wifi

Because of the large amount of wifi routers in dormitories and other devices disturbing the 2.4 GHz network (e.g. mobile phones with bluetooth, microwaves,…) it is possible that there are connectivity problems and low bandwidth between the wifi router and the connected devices. The network provider has no influence on this because the wifi frequencies are open to use by anyone. The network service by the provider ends at the network socket in your room. We cannot provide support for wifi networks set up in your room.

If there are connectivity issues (connection loss or low network speed) use a network cable to connect your device directly to the wifi router. Disable the wifi network card on your computer and check if there are still network issues.

If the issues are solved by using a network cable, there may be too many active wifi networks in your vicinity disturbing each other.

Reduce wifi problems

The reason for problems within the 2.4 GHz wifi network is that there are only three non overlapping channels (1, 6 and 11). All devices (your own and from neighbours) have to share their bandwith on these few channels. If there is a lot of traffic within the wifi networks, the risk of connection loss and low speed is very high.

A suggested solution is to switch to the 5 GHz wifi network (802.11ac), if the wifi router and the connecting devices are supporting this. Check the manuals of your devices to find out if they support 5 GHz wifi using the standard 802.11ac.

The 5 GHz wifi network is providing up to 19 non-overlapping channels and there are fewer other technologies, which are using this frequency.

On our website you can find a list of recommended wifi routers which support 5GHz wifi in addition to 2.4GHz wifi.

You can check your wifi environment with diagnostic tools (e.g. Netstumbler/iStumbler). Depending on the number of existing wifi networks you can decide if other neighbouring wifi networks may disturb your connection. Check out which channels (2.4 and 5 GHz) are in use:
