Sorry I didn't get right back to you. I'm 69 and have a lot going on. I didn't see any response to the systeminfo scan but anyway on Thur. I shut down th McAfee ight firewall for 15 minutes and it connected immediately. last night I finally got it to connect using bluetooth also. I tried same w/the Toshiba with no success I'll try again later. I thank you very much for your time and expertise. I've been working around PC's since I got one from DuPont in 1998. I have learned a great amount since that time. Between  AT&T, APPLE, Microsoft forums over 6 or 7 hours with nothing being successfull. Again I thank you very much. Bob Kirby
