After calling Comcast with this new info they booted me upstairs to their Wireless advanced Team and a nice, knowledgeable guy ignored everything I had to tell him and started from scratch, working directly on my new Comcast router, fixing issues, adding new software (or whatever). He came back and assured me the router was now much more powerful and the problems were solved. I was so grateful! Since then I can't open videos, can barely read regular emails, in my Windows Live Mail and that program (WLM) is extremely slow, intermittent. Sometimes the email quits because it hasn't received a response from the server. Also, the internet is sometimes quick and other times takes forever. Meanwhile, the customer service from Comcast is ineffective and from Windows is non-existent.
The 2 error messages I am getting is 0x800CCC0F and 0x800CCC19. Once the SSL was secured and most recently it wasn't. Also it referenced an insecure socket error: 10053. Windows 7 Home Premium.
All of this because I simply wanted to secure my home network!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
