These methods don't work for me and I still not get access to my LANCOM router!

Nothing helped and you don't have access to your router? Then you can do a factory reset. In most cases you can perform a factory reset by pressing a small button on the back of your LANCOM router for about 10-20 seconds. Afterwards your LANCOM router lights up and needs several minutes to reset the settings. Because of the factory reset your LANCOM router loses the connection to all other connected devices and some devices have to be reconnected to the router after such a reset. If you are unsure, you should consult an expert to help you set up the router again.
