PS3 can't connect to the internet at all
My COBRA PS3 has suddenly started having issues connecting to the internet over both wired AND wireless internet. It cannot see any networks over WiFi, even open-security networks just a foot away. Over wired, it cannot even get an IP address. I tried manually entering an IP address, which seemed to work (Reported successful when getting an IP address and an internet connection, but failed when connecting to PSN), but then I got the 80710102 DNS error whenever trying to connect to the internet. So I tried manually entering various known-good DNS addresses like 8.8.8.8, 8.8.4.4, 1.1.1.1, etc., but I still got the same error. Even in the web browser, I get that DNS error. Is there anything I can do, or is there something more fundamental wrong with my PS3?
