I read somewhere that the Sony PSP 3.80 upgrade might be out soon. So, I fired up my PSP for the first time in a long time and checked for system upgrades. 3.80 is not out but 3.73 was available. So, downloaded it over a WiFi connection and upgraded the PSP’s firmware. After rebooting, I fired up the PSP’s WiFi again and was unable to connect to my access point?

It turns out that the 3.73 upgrade changed something about the way the PSP WiFi settings worked. I ended up creating a new profile (very easy to do) and was back online. I wish Sony had put some kind of warning about this in the informational text they provide during the upgrade process.
