Im downloading dc universe online right now but , i checked my internet connection and saw my nat type was set to type3 , mostly when that happens i just reset my router but now i dont know i can , will my download abort and will i have to start over again ? i noticed when i go to the xmb screen the download stops untill you get back on the screen , so maybe i could do a quick reset ? Just hope i dont have to do my download over again 'thx
NAT Type won't affect your download speed. Just let it finish.
If it really bugs you, then turn off your PS3 using the controller or by pressing the power button once. Then reset your router. Your download will resume when you turn your PS3 back on.
You should look for firmware updates for your router then. Get the model number and version number from the sticker underneath it, and visit the manufacturer's website.
