Please understand this is not 24/7 instance reply service and people reply of their own concern not when somebody demands it.

Make sure that website is not blocked by your firewall at computer. Blocking website from Netgear is likely done in office environment or in case of child protection (instead of making this configuration for each computer on the network)

As in regards of access to your Netgear:

• to gain access to Netgear use internet browser (Firefox, IE, Safari) and type http://192.168.0.1 (can be different if network IPs been custom configured)
• default username and password if you did not change it is "admin" and "password"
• if you changed this details previously and now cannot remember it, there is only one option left as far I know and that is RESET button at the rear of Netgear. BE WARNED, THIS WILL SET YOUR NETGEAR TO DEFAULT FACTORY CONFIGURATION AND REMOVE AND ADJUSTMENTS YOU MADE TO IT. PLEASE MAKE SURE YOU KNOW YOUR CONNECTION SETTINGS BEFORE DOING THIS. The reset button is mostly around plug for power adapter at the rear. For better idea where to locate it, check netgear.co.uk or *.com support section that also host latest firemware and various guides for users.
