@ ashu-
thanks for helping.
no, it does not ask for anything. it takes "utstarcom" as SSID by default and my network is unsecured so no password is asked for.
i set up new connection then scan and it finds the router. then i > with all default values and save the connection, but when i test it says no gateway reply.
once i set up with manual address settings- gave random ip to the psp and got the default router and dns by ipconfig on my laptop. that resulted in my laptop connection getting disconnected but still the psp wouldnt connect...duh
Why did your laptop disconnect when you did a ipconfig is a mystery...
Try the following:
1. Log-in to your router [default is 192.168.1.1 through any browser. Default userId and password is admin.]
2. Check the SSID of your router.
3. Check whether any filter is enabled.[MAC address filter which blocks all other devices except the one in the filter list]. If yes, add your PSP MAC address to the list.
4. Check for any encryption. [You already said unsecured network, so ignore].
5. Check which wifi profile is currently running. Change it to 802.11 b+g [Both b and g profile should be enabled.]
If you do a manual config, Set your laptop IP as 192.168.1.x and PSP IP as 192.168.1.y
[x and y should be different and in the range 2-254].
