I have tried everything to get netgear on to my laptop

Try RESETTING your Netgear back to the default settings and configure it again.
To RESET the Netgear, power up the Netgear then press andhold the RESET button at the back of the router until all the LEDs flash. Connect a LAN cable from the Netgear to the LAN port on yourcomputer, open a browser and enter the Netgear configuration URL -
http://192.168.0.1
The default login = admin
The default PW = password You can now change the admin password and configure thewireless settings.
Go to the wireless configuration and set up the SSID and WPA or WPA2encryption.
Apply these settings to the wireless card in your laptop/computer.

To secure your wireless network from unauthorized access, please click on thislink and follow my instructions :- http://www.fixya.com/support/r3559128-wireless_router_security

The Security Key is normally used for Wireless routers to protect your connection from any unauthorized use. As you have said that you do not have the Security key for your router with you, the best way to connect your ACER laptop to the Netgear router is by asking your Wireless service provider to reset the security key & freshly reentering the same on both of your HP & ACER laptops. 

Your laptop may not be compatible with the n+ or you might have the security settings wrong try plugging your laptop directly in and try tweaking the setting there.

i think u have soem firewall isse in router also try to reset router then check .
reset switch in back side of router.pres it for 10 seconds .then it reset to defaults.

A few things to look at:

1) On the front of the router, is the wireless LED lit up?
2) If it is not then it is either disabled or dead. Connect the router to your pc by cable and in a browser window enter 192.168.1.1.
3) At the login screen enter admin for the user and password for the password.
4) Once you are logged in, use the wizard to setup your wireless connection.

Good luck and thanks for using FixYa

Please try to use a difrent DNS service.
For example open DNS:
Primary: 208.67.222.222
Secundary: 208.67.220.220

im pretty sure you will be fine if you bypass that step, or simply disconnect the modem from your router during that step.

Most laptops have a wireless card built in them and if you have one you should try using that instead and form past experiences USB adapters don't generally work on laptops in which case if you laptop has the slot for it you should buy a card like this http://www.netgear.com/Products/Adapters/SuperGWirelessAdapters/WG511T.aspx

try to set up a secure network using wpa2 with a long passphrase. also turn off the wireless signal when you're not using it.

You can try changing the wireless network name or ssid, change the wireless channel to 11 and enable WPA as the wireless security.Just open IE then type http://192.168.0.1 on the address usernama is admin and password is password then do the changes there.
