Dell Inspiron 15 Laptop, In-home wireless network, no other computers, running Windows 10. ISP is Cox Communications.
I get occasional messages in the lower right corner saying "Cannot connect to the Internet. Please verify your Internet connection and try again". I do not believe those messages, because I do not notice any interruption of anything that I am doing when they appear. The messages are accompanied by a white "I" in a blue dot. The messages appear about every few minutes and stay for about 5 to 10 seconds. I have been using Windows 10 for many months. Please advise. Thanks,

Sam K.
