I'm sorry if my english isnt ok. I'll try my best

I looked and it says it is a A1 model with 1.02 FW I believe it said. From what i understand the only difference is the firmware version that it is shipped with?
I read a little here and I know sometimes it is important to update things to the latest but I see that a lot of people have some problems with the updated firmware.
I just want to know if i should update the firmware to a newer version and if so, what one?
Also, I am using this mainly as a wired router. I have 2 PCs that will be wired but I also have a playstation 3 that will be wireless. Sometimes it will be wired, but mostly wireless.
What is procedure to make sure the playstation3 will connect and how do i update correctly?
any help will be appreciated
