PSP DNS Error

[SP_FREAK]

I had to replace my router and now I can not connect my PSP to the internet anymore. My computer connects no problem.
I keep getting a DNS error on the PSP.
Does any one have a fix for this error?

Play Station?

looks like it has failed to get a proper address for the DNS -- open the config
and set DHCP for both IP and DNS.

(this is what is needed, but not having any such, have now idea on how )
