Let's login to the NETGEAR so you can view/reset your password.
Make sure you are plugged directly into the back of the NETGEAR into 1 2 3 etc. (this needs to be done from a computer that is directly plugged into the back of the NETGEAR, this will not work wireless)
Open your browser and go to address http://www.routerlogin.net
For the username/ password...
username is admin
password XXXXX XXXXX
On the left pane click wireless settings and then security.. HERE is where you can turn OFF security and then connect from your laptop with no password.. or just retype a new password XXXXX and click save.. then type what you type there into your laptop to connect...
Ok do you know who installed the unit? Sounds like they changed the default login for the router itself.. (any idea why?)
Do you have it written down somewhere or do you have a contact for the installer?
