Fixed wireless internet available at my address but no signal???
So I have been checking regularly, eagerly anticipating that fixed wireless internet would be available at my address. For 6 months I got the "not available" message. About 2 weeks ago, I check again, and it says that fixed wireless is available at my address. I set up the installation, the date was set 1 week from my order date. The tech shows up, arrives in a timely manner and is a nice guy. He checks for signal but can't get one. I know for a fact that there is a third party owned tower 3 miles away, direct line of sight, from my house. There are also Verizon and other towers within 5 miles or so. The nearest AT&T, owned tower is 15 miles I believe. I was under the impression that AT&T were also upgrading third party tower sites, as well as building new towers, in order to meet the CAFII obligations.
So I live chat with customer service, not quite satisfied with what the tech was telling me. The customer service rep tells me that it is indeed available and that he will make a second appointment for 03/31/2018. He tells me that he has contacted the supervisor tech who deal with my installation. He also tells me that they are working on running DSLAM to my site to get me up and running. I am now a little confused. I am not an expert on the technical side of things. What is this DSLAM? Is it a part of Fixed Wireless Internet service?
I guess my real question is, was the customer service person right or will the second appointment just be a waste of everyone's time? Does installing DSLAM mean that they are fitting the tower that is closest to me, (the third party owned tower), to be able to send my wireless signal?
