I'm going to answer parts of several users' questions in this post. Y'all have offered much information, but I cannot address all of it. Please keep in mind, I've had the same setup I have for 7 years. Until right before we started this thread, I have never had speed and connection issues, except for one or two neighborhood outages and that kind of thing. I could always get total internet with fast loading pages and games, etc., anywhere in the house. There are no additional game modules (X box type) since we've been here. In fact, we have two less internet users, since two kids have gone to college. So, I am paying for 25/25. But, since I am a "Valued Customer", I have an "upgrade" to 50/50. Seems like BS, since I often can't achieve a connection at all. The only place I cannot connect predictably is in the master BR. I do not know how to answer copper, or phone line, etc. I know it is cable modem. The FIOS modem/router is in a wall utility box (looks like a fuse box) with several cables that are for use with TV cable, internet cable, satellite and so forth. There are many cables in the box that aren't in use. I have the wifi on this modem turned off. In the office, there is a jack. The ethernet cable comes from there and connects to Vonage phone and my airport extreme (the flat one - not Time Capsule).
I run or try to run speed tests most days with the ookla app.Sometimes I cannot even connect to run the Speed Test. Results have varied, since June 25th. Here are some results: 5.75 dn/22.4up to 4.32/4.03, 38.3/22.2, .07/3.29, .11/3.55, 5.64/9.57. These are with the iPhone X. For whatever reason, the iPad is much worse and mostly in the mornings, I can't get a connection at all. So, when I connect, it is good and some of these speeds don't matter, because things will work. But, on most occasions, I am unable to connect with the speed test app to even run the test. So, that is zero speed down or up. I spoke to Frontier. The IT guy said that since I have wifi turned off on their modem, it is not a Frontier issue. He said there are many things that can block wifi signals. I can't think of anything new in my home. Like I said, no new game systems, or other devices. So, having posted all of this and having gotten great information from y'all, my next question is how do I solve the issue? Is there a wifi extender that I can connect? What suggestions are there to boost the signal? I have updated the airport firmware. Thanks, again, for patience and your valuable input.
