If you have not already, you may wish to post this in the support forums. If this is just a HOME issue, post your thread at the HOME support forums. If you can not log-in to your account at all, post your thread on the Playstation Network support forums. It looks like you noted your error code, and that is going to help Joystick_Warrior or other support mods quite a bit. The support forums should also allow you to search error codes(I think, not 100% on that).
With regards to your wireless connection, have you tried power cycling your equipment yet? If not, that may help. With regards to HOME, what you may want to try is an uninstall/reinstall of the HOME application. Time to completion on this varies depending on connection speed.
Good luck with your issue, and hope you see it resolved soon. Welcome to the forums(from a fellow forum user).
