{PPU Thread[0x6f] (tool_client_thread)[0x0027b624]} sys_net: socketselect(): error 38 Error all the time :/ If i disable NETCtl it gives to me that error {PPU Thread[0x1] (main_thread)[0x0027b9a4]} cellNetCtl: cellNetCtlGetInfo(IP_ADDRESS): GetAdaptersInfo buffer overflow.

Log please. I'm guessing you tried to LLE cellNetCtl? It obviously isn't going to work, as it can't interact with your OS's networking stuff.
I'm not sure why that error always occurs the first time. After the error occurs the code does buffer resizing and tries it again, and I've never seen it fail after the error handling.
I feel that I implemented that part quite poorly and I'd like to overall rework it to be more reasonable, use smart pointers and to remove a lot of duplicate code.
