Ok, my colleague left our company being the only person knowing the key to access our wireless network.
I've tried to restore the manufacturers settings by turning it off and holding in the reset button for 30 seconds.
According to articles i've found on the web, the default address should now be
http://192.168.1.1
However this displays page cannot be found.
Can someone shed some light on how I can access the web interface of our router?
