Home Internet - Frequent Disconnects - Possible Fix

Thanks for replying. My son is flying in to visit Thursday and I will have him make sure everything is set up right. My grandson is on the spectrum/Asperger's and sports is his life. I put over $1000 into a new antenna and rotor for OTA. Also set up the newer coax. We live in the country, about 50 miles north of Detroit. Some OTA towers are closer. We are limited to wifi access. I went with TMO hoping it would work and price was good. I have been reading and watching you-tube videos. I find sites saying some units work better for some customers. I am hoping we can resolve the issues soon. My gateway always has 2 bars when working. Never more. Sometimes a yellow circle with X in center. If my son can't get it to work good, I will try a diff. unit. Once again, I thank you for answering me. 😊
