What does WPA key mean on psp

You did not elaborate further why you cannot connect you PSP to internet. But I will assume that you have a wireless connection within reach and that your PSP Wi-Fi switch is turned on (switch on the right).
1.) If your wireless network requires a Network Key (WEP or WPA), you need to know the exact key to be able to connect to it. 2.) To connect to internet, open Internet Browser in your PSP and this will prompt you to connect to a Wireless network. 3.) To set-up, press the 'scroll right' button (>) until you reach the "Network Key". Choose the type of key your network is using (WEP, WPA or other) then press 'scroll right' (>) again until you reach the last menu. 4.) If you do not encounter any error, you can start browsing. If you still do, you may have to leave the specific errors or further details of your problem for us to assess...
P.S. My favorite is God of War (I hope you have tried playing it)...

Sounds like there is something going on with the security key which is usually WEP or WPA and the psp may not be accepting it. Make sure on your wireless router that you don't have a key enabled on it. Best best on most routers. Hold down the reset button for 30 seconds and let go, this will reset your router to factory defaults.
Now that your router has no security on it. Try connecting the PSP to the router again. If it connects then you know the security key was corrupt. Now you can go ahead and put the security key back in. Make sure your PSP is configured to use the key so it can connect.

You would need to enter the WPA that is being used by your router. This is like a "password" of sorts that prevents other people from using your internet connection without your permission. Once you find out the WPA key (it should be in your router's configuration), you can either disable WPA on your router, or enter it into your PSP.

The WPA key is related to the router used for the wireless connection to your PSP. If you go to the security menu and enter your routers WPS code, you should be ready! (The code should be available from your internet provider if you don't have it handy.)

i suggest turning off the wpa security thing, to do this type 192.168.1.1 or 192.168.1.0 in your internet browser on ur computer. every wireless network databass is different. the first 7 digits number are the same. for example every network databass starts with 192.168.1 and the last digit is different. if u try the ip i gave u above and it still doesnt work.play with the ip thing by switching the last digit to 1 through 10. for example: 192.168.1.2 and 192.168.1.3 and so forth, then try connecting it to the network. o yea..... in order to gain access to the databass, u will have to be administrator which u can obtain it from ur internet provider, just type in admin in both username and password

1. Disable the security features. (this means that you don't have to enter any password when connecting PSP to the router)
2. Reconfigure your PSP: no security
3. Test your connection

The WEP and WPA key is configured in the router's wireless settings.
WPA is a stronger encryption than the older WEP encryption, I suggest you use WPA or better still WPA2.

UR PSP IS INSTALL THE NET CONNECT SOFTWARE

means the wep key you are entering is most likely incorrect. Go into your router settings check somewhere under wifi or wifi security. You will say it says wep or wpa look at the code that is on that screen and enter it in your psp. That should be the fix that you are looking for.

This is the password to your wireless network.

Why can't I connect to the internet on my psp I tried over & over nothing it says the connection to the acces point has timed out..
i still can't connect even with wireless router
