Before I recieved error DNS 80710102, I had another error that my PS3 was unable to obtain IP address due to timing out. I however manage to successfully resolve it by configuring the IP address manually through custom and not EASY setting. Nevertheless, after testing I recieved another error and that is the main problem now, the DNS 80720203 error. I've tried every possible solutions I could find searching on the internet from disabling the router, to changing the DNS numbers and restoring my PS3 to default setting. But it works on wired btw...
Hope for a solution asap and btw, my PS3 is a 12 gb slim model if it has anything to do with the error.
Thanks in advance
