Hi Bensheim,
You can download a PDF of your router's User Guide from the
Netgear Support downloads area.....
What you will need is the IP address of your router (which you can read from within your own Mac at the System Preferences / Network prefpane --- it's listed when you highlight the Airport network, the one with the green dot beside it, then click on the Advanced button down at the right hand lower corner to bring up your network settings, then click on the TCP/IP tab at the top to show the IP address for your router).....
If you were to simply send your Safari browser to that IP address, it would take you directly into the control pages embedded within your router.....this is where you would need your changed password to log in. In the event that the password and user ID remained at their defaults, the login would use the information found
HERE.....
Once logged into the embedded control pages, you should then be able to change the Wireless security to enable encryption.....my recommendation would be WPA and then make a user-friendly passphrase that you can recall easily (14 characters in length is best, and it should contain letters, numbers, punctuation and capitalization so that it is more secure)......a good example that meets this set of constrictions, yet remains easily remembered, would be something like ----Bern!e&A1ici@2 ---- using ! to substitute for 'i' and the numeral 1 to substitute for the lower case 'L' and the @ symbol to substitute for the lower case 'a' in the names "Bernie" and "Alicia"......
Hope all this doesn't provide sensory overload, as the process of encrypting your wireless network is really straight forward at the root of it all.
