Online homebrew not working....

Well, my infrastructure wifi isn't working in 1.50 kernel homebrew. I don't know whats causing this, but i am using Undiluted Platinum and 3.03 OE-C (for GTA cheat device). Whenever I need to select an internet connection, it doesn't recognise there as being any. I do have internet connections set up on both firmwares and they do work on 3.03 kernel homebrew.
There are 3 apps that aren't working correctly that I noticed so far - iRShell's nethost, Triple Triad PSP's online infrastructure, and the Installotron.

If you need more info on solving my problem, just ask me. I've tried everything to get it to work, and i dont know what else to do. If you even have an idea, post it.

Thanks a lot!

Do you have any custom .rco's .prx's game boots running on your psp?
If you do try putting all the old ones back in and that might work... If not go back to 1.50 then back to 3.03 OE-C you may not have got a good install...
