I have always run my laptop on Wireless Connection. Recently (about 2 weeks ago) when I first turn on my laptop for the day I get an asterik (yellow star) in my Network Bar. I checked on line and found just about everyone suggesting going into Network Sharing and removing that Network - restarting computer and reconnecting to my network - which I did and all was good that day. The issue seems to be that every time I power off the laptop and power back on I get this yellow asterik - about 90% of the time if I connect to net anyway I get a message saying my connection is not secure. I have tried to everything thru research on the net to get this to stop doing this permanently, but nothing is working - still there each time I turn on computer. I can get into the internet and on all my pages that I have tried in last 2 weeks, but I just am not getting why this asterik is there when it never was before - I have changed nothing on my computer at all. I run virus and spyware at least every few days. We have been using the same modem/router for not quite a year and there are other computers, tablets, phones, etc. using the same network and modem/router and no one else seems to have these issues - or at least haven't noticed them. I am really at my wits end with this.....I want this gone and my security back!! Any help is appreciated - thank you,
