I recently reset my wireless router to factory settings because I couldn't access the interface to change its settings (because I couldn't remember the old username and password).

 

I went through the netgear set up run-through, completed it, and it said the internet is ready to use.

 

 

However, when I open an internet browser it says "(192.168.1.2) is managing this device" and nothing else comes up.

Also when I open wireless network status it's reporting that I have full signal strength but no internet access.

Any ideas what the problem might be?

I had this issue with my Netgear router not so long ago, actually. My flatmate was the one who dealt with the problem, so I'm not entirely sure what he did. I think he ended up calling our ISP and they were able to fix it for us.
