Over the past couple of weeks we’ve been having a problem with our Netgear DG834G router which we use to share our ADSL connection. For some reason, it randomly stopped accepting the correct username and password – at the moment only I know the login credentials and I don’t remember changing them. This is annoying as you need to be able to access the router control panel to be able to enable port forwarding for those applications which do not support UPnP.
What made it worse was that the password reset instructions at Netgear’s site failed to make a difference. The router would simply not return to its factory defaults – it still had our ADSL settings (since we could still access the internet) and the bad login credentials.
Thankfully a kind soul on Netgear Forums had this solution: Unplug the RJ11 (phone line connection) and then hold down the reset button for 10 seconds. That worked for me and all the router’s settings were erased, including the username and password, so we were good to go again.
Remember to have your ADSL username and password handy as you will need these to be able to access the internet again afterwards, and that any other settings like port forwarding will be lost.
