Question : Problem: Web interface for Linksys Wireless-G WAP54G

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?

The reason that it does not work is most likely that you are using a straight through CAT5 network cable.
If you are connecting a device such as this, or another computer directly you need to use a "Cross Over" cable which is wired differently.
Or, you need to connect your access point firstly to a Switch/hub and then connect the computer via cable to the switch. This will automatically cross over the connections.
