8001000A error problem?

i keep getting this error code whenever i try and connect to my dad's router. but this morning when i was at my mom's it worked fine.

also whenever i try to scan for wireless connection, it gives me "the access point was not detected".

Anyone know what caused this error code?

Make sure all the router info on your PS3 is right. A lot of people get the DNS error.

so its not a big problem that has to be sent in to sony?
