The short version is what do you want to be on CEX or DEX .
Dex is better in every way but is less forgiving when stuff goes wrong.
CEX is safer and it's easy to fix.
This is the most up to date thread on Ps3 modding and they are all on point on that site.

Okay, I know you're confused, and we can get this thing done over with, What does it say when you connect wirelessly? Give me examples what you've done and we'll go from there.

Debug Settings" and make sure all the following setting are selected.

Release Check Mode > Development Mode
Boot Mode > System Software Mode or release mode (see which one works for you)
Network Settings for Debug > Single Setting

Hey guys so me and some other guys got it to where I can connect to my router. Yesterday we were unable to get my system online. After dumping my PSID and using Ninja, Id go to Sign up for psn ( This console has never been on psn before) when trying to create an account or use an existing one, it always says The connection server has timed out. If Any of y'all have experienced this id be interested because those who Ive talked to don't know how to help anymore cause they did all they knew :/

Yes I had simpler problems like that each time my account got banned on PSN it said it had an error occurred so what I did is go on PSNinja and clicked the 5 Options, turned off my PS3 turned it back on and then it worked for me. Try this for yourself to see if this works for you. It's a really weird method from not having a error when trying to make a new PSN account.

I will try that when I get home, hopefully it lets me make an account I wanna get online and get to hosting lol. I've already ran into enough problems having a Mac lol

Make sure that your NP Environment is set to NP and not SP-INT in Debug Settings.
Has that will give you a timed out message.
