 I don't receive WiFi at my favourite place anymore, what can I do?

The WiFi of the RWTH provides wireless data access for mobile customers, please change your location. A failure of an access point may well last longer. General faults are listed on our error pages.

 I receive the eduroam WiFi in my kitchen. Am I allowed to distribute it in my house?

The network rules of the RWTH forbid such actions. If you try something like this, we are forced to disconnect your WiFi adapter if you disturb the network traffic drastically.

 My WiFi IP is 169.254...., I can't surf, what is wrong?

Your WiFi adapter did not connect to DHCP server and therefore did not receive a correct IP address. This error can have various reasons:

  • you are not connected to the WiFi (anymore),
  • the access point you are connected to is defective and/or is not connected to the system (anymore) or
  • you are connected to an access point that does not belong to the RWTH.
 My WiFi IP is 192.168...., I can't surf, what is wrong?

Either you are connected to a WiFi network that does not belong to the RWTH or your network adapter is configured to have a fixed IP address. Make sure that your WiFi adapter is configured to get its IP address by DHCP.
