I have had problems with "stick keys" with one of the PSP's I've had. i don't push the button but the car pulls to the right. if you have had it for a while, it may be that finger grime has built up under the button therefore closing the connection with something as little as a shake. if you just got it, it should still be on warranty and i would suggest having it replaced. service to get it fixed or find out any other prob it may have would just be costly. hope I've helped. again, i am just speaking of my own personal experiences.
Turn on your PSP by moving the power button on the right-hand side of the console in an upward motion. Under the console's main screen, go to the "Settings" icon. This is the first icon listed and is farthest to the left. From the drop-down menu, choose the "Network Settings" option at the end of the list.
Select "Infrastructure Mode" and press the "X" button. Select the "New Connection" option to add a wireless connection to your PSP. Choose the "Scan" option to instruct your PSP to search for accessible wireless connections in your area.
Select a wireless connection from the connections your PSP is able to access. Confirm the name of the network and press the right arrow button. Confirm the security encryption settings for the connection. In most cases, the PSP will determine the network's encryption automatically. Enter the wireless connection's password if the network is secured.
Name your new wireless connection so that you will be able to identify it in the future and save your settings. Run a test connection to ensure you are able to connect to the Internet through the wireless network.
Press your PSP's "Home" button at the bottom left-hand side of the console. Move your cursor to the right to find the "Network" icon. Select the "Internet Browser" option from the drop-down menu. Press the up directional arrow and press "X" to enter a web address into the browser. Once you enter a web address, your PSP will automatically connect to the Internet using the WiFi connection you set up previously.
