Our Wifi is acting up and I'm unsure what exactly I should do. I tried the self-help internet programs online. Is there anything I can do at home to have our internet wifi reach every room of our home. It's a ranch style, 1600sqft, 1 story home. It used to reach almost every room but now it will not go further than our den where the router is located. We just bought an Alexa Echo so we want to have that in the front of the house but it is unable to connect. Will I have to call a technician to come out or is there something I can do on my own?
