Possible solution for unidentified network access

Solution to unidentified network: with additional suggestion

I also thank you Omar. I spent 16 hours trying other suggested solutions before this.

One additional suggestion for folks like me who have their router set to only accept certain MAC addresses:

the 12 digit number that appears in that line of the ipconfig /all is the MAC address of the NIC. I suggest not inserting your MAC address rather than a random number.

THANK YOU VERY MUCH!!!! that worked for me!

That's the craziest thing I've seen in a while... I just switched from AT&T to Comcast and couldn't get it to connect. I was ready to start punching myself in the face. And then I saw this... why not. And it worked right away! THANK YOU!!!
