Wifi problems

When using an old wifi router with wifi standard 4 (or older), temporary or permanent disturbances of Internet connection can occur or even complete outages.

Caused are those problems by an increasing number of wifi routers in the environment (those of neighbors for example) and by other radio systems which are using the 2.4 GHz range, since there are only three non-overlapping channels (1, 6 and 11) on this frequency. The more radio traffic (wifi, Bluetooth, …) there is, the higher the risk of low speed connection or connection loss.

As network provider we have no influence on this since the wifi frequencies are free to use by anyone.

Reduce wifi problems by usage of 5 GHz range

It is strongly recommended to use a wifi router with wifi standard 5 (or better) and switch to the 5 GHz frequency supported by this type of router.

In the 5 GHz range there are up to 19 non-overlapping channels available, which are in addition also not shared by other radio technologies.

Whether you device (computer, smart phone, …) is suitable for the 5 GHz range can be easily tested or looked up in the technical specifications of the device.

For a list of wifi routers which are supporting the 5 GHz range take a look at recommended wifi routers.

The network service of the provider ends at the network socket in your room. For the wifi set up behind it, no functioning guarantee can be given.

Additional information

Whether network issues are basically caused by adjacent wifi networks can be checked by disabling the wifi on your router and connecting the computer by a suitable network cable (cat 5e or better) to the router. If the connection is stable, the connection problems are likely caused by too many overlapping wifi networks nearby.

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:
