“Click on the Apple logo in the upper eft hand corner and choose System Preferences, then in the third row down, choose the “Network” icon. Then click on the Advanced button in the lower right. With the WiFi tab clicked, you will see a list of Preferred Networks. Find the network called “xfinity,” the one that does not have any security in the righthand column. It will say “None.” Highlight that one and then click the little minus sign just under the box on the left. That should remove the “public” unsecured xfinity that is causing the problems. So far, at home, working on my laptop for the last two hours I have had NO problems. Fingers crossed that it works for you.
“Again, thank you all great neighbors!!!”
