There are multiple reasons for that. If you are sure that the device is functioning properly you might have two problems. First one is you are out of range. And second one is your network is configured not to broadcast the ssid.
The SSID is the identifying 'name' of a wireless network. The PSP can connect to wireless networks, you can set it to scan for one, or if you already know the name, enter it manually.Obviously the SSID will be different for every PSP, but the SSID itself is a property of the wireless network, not the PSP itself, you're just entering it into the PSP so it can recognise and access that network.
An SSID is the 'name' of a wireless network, it doesn't have to be a number.
The ssid is used for identifying you wireless network so you can see which network is your and which is your neighbors
SSID
SSID stands for Service Set IDentifier. it is the name of the wireless network you are connecting to.
The SSID you use is the one for your own wireless network, you set it when you set up the wireless router. So if your network is named 'MyInternet', that's the name your router is broadcasting. That's the SSID that the PSP needs.
SSID
The SSID is the 'name' of your wireless network. So when it scans for wi-fi signals, your connection should show up on the list, that's the one you choose. Of course if you don't actually have a wireless connection then there will not be a usable SSID, those others belong to other people.

An SSID is simply a name used so that people can identify a wireless network. The "best SSID" to connect to in any case whatever your home network is called.
It's short for service set identifier
