i cant access my internet on my psp

To connect to the internet on your PSP, you need a Wireless Router or Wireless Access Point. Once you have a wireless one, you should know the name of your router. That's what an SSID (Service Set Identifier) is.
Once you know this information you should be able to find your router on your PSP. Once you do you should have a password on your router so no one you don't know can use your internet. When adding a connection on your PSP you will also need to enter the password for your router. You can use WEP, WPA-PSK (TKIP) or WPA-PSK (AES). WPA-PSK (TKIP) or WPA-PSK (AES) have very high security and WEP has a lower security.
Once you have added your connection, just type an address and surf! Not all websites will load because some require too much memory.

Assuming you have Official SONY PSP Firmware, Update to the latest version by going to Settings>Network Update. Locate your router and use it as the network connection.
Download the needed files and update by going to Game>Memory Stick>PSP Update.

Once you finish Update, go to Network>Internet Radio>About Internet radio. It will take you to a website to download the files needed and will install to your Memory Stick.

To put music on your Memory Stick, the Music must be MP3, AAC, M4A or WMA format.
Open your memory stick on your computer by pluggin in a USB cable to your PSP and going to Network>USB Connection or you can put the memory stick in a card reader.
Once in the root of your memory stick, there should be a folder called "Music". Put your music in there or in one more folder inside that. Two folders inside of each other will not be playable.

Place videos in the "Video" folder on the root of your memory stick.
Videos need to be MP4 format. 368X208 Highest MPEG4 Codec, or 480X272 x264 or AVC codec.

That's problem occurs when there is some problem with the firmware, and any some process under psp has running. you'll need pandora battery to solved the problem. when using pandora, you can go into service mode of your psp, then downgrading your psp back to default setting. what type of your psp? Slim or phat?

You can replace the switch else you just have to open ur psp and in the left corner you will be able to see a switch u just have to push it up.Now the wlan switch will allways be on and u could use it whenever u want... The best thing is to give it for a service...
