I’m hoping my advice on fixing “Error 80710102” is helping some people connect their PS3s using a Comcast cable modem with battery backup.
But I did neglect to mention one other thing. You may go through the process I described, and get another error, or not be able to sign into the Playstation Network, and so on. Because what I forgot to mention was, once you follow my instructions, you will probably have to reboot the Playstation 3.
That’s all. Minor sin of omission on my part. My bad.
Good luck with your online gaming!
