Wireless Problems Zyxel P660HW-D3

When you defined the name for Wireless connection with you new router, did you give it a new name? If this is a case then you can delete the old name in your available wireless network list in your lap top so it won't go back to the default one which is the old one, then you are all set.

HELP!!!!!! Trying to enable wpa-psk security on my laptop?

You should set the security on your computer wifi card to wpa-psk and then type in the securitycode which is written in your Zyxel Router.
If this is not possible with your networkcard, change to wpa or wpa2 inside the Zyxel. And do the same procedure with your networkcard, when detected the Router.

How do you access WPA Key Settings on a ZyXEL modem?

To access Zyxel configuration/setup utility, launch a web browser (Internet Explorer, Opera, Firefox, or Netscape, etc.) on your computer, type in (default IP address for most Zyxel wireless devices) in your Internet browser's Location/Address bar, and then press Enter on your keyboard. 
If presented with a user authentication (login) screen, try the following:

Default Username - Zyxel Wireless Router: N/A (none, leave blank)
Default Password - Zyxel Wireless Router : 1234 

If you cannot login using the above, verify that (a) you are entering your password correctly, and that (b) your CAPSLOCK key is off. It could also be due to the firmware (a set of instructions stored on an EEPROM microchip) on your Zyxel product being corrupt. If so, you would need to reset your Zyxel WiFi router to its factory default settings.

IMPORTANT: Do not forget to promptly secure your Zyxel router (using a strong password, a non-obvious WEP Key, etc.) following a reset to factory default settings. Failing to do so may potentially expose your entire WLAN to scammers.

*Your vote is highly appreciated. Thanks in advance.

Zyxel Modem Router P660hw wont work on LAN

If a LAN connected PC will not work while a wireless laptop is connected you need to go into advanced router setup, bandwidth management, and untick the three boxes labeled "active" to disable the band width management. Easy!
