Network Congestion

I don't know what you mean by home net vs TMO home net. I have ONLY ONE home wifi network. It's the SSID of the Arcadyan Router sent to me by TMobile Home Internet (TMHI). It sends out a signal both over ethernet and over wireless to allow my devices to connect to the Internet.

The Arcadyan is connected to an external MIMO 4x4 antenna to boost the the Arcadyan's ability to receive a signal from the TMobile transmitter on the tower (about 2 miles away in town). The MIMO is mounted outside of the room where the Arcadyan is set up. The MIMO antenna's wires run through the wall and feed into the Arcadyan. 

In addition to the TMHI set up I have TMobile cellular service on my iPhone. I added a Wilson Whole House Cell Booster system. The Cell Booster Antenna is mounted on a 20 ft high antenna pole. The cell booster antenna's wire feed in through the attic and down into a room that has a powered device that then boosts the signal into the home's various rooms.  

If I turn off the Cell Booster unit (wired into its own antenna) then I have no indoor cell phone signal. No bars, just a display saying "no service". When turned off, if I enable the iPhone setting to use "wifi" (off the Arcadyan) then I sometimes can get one bar but the phone is incapable of receiving calls. If I try to make a call it sometimes rings, sometime doesn't. If it does ring through the caller cannot hear me and the call drops rather quickly. 

I can disable the iPhone setting to "use wifi" and that doesn't affect my ability to make or receive calls as long as the cell phone booster is powered up. When the TMHI is down, my cell phone still works.

If I turn off the Arcadyan and use my cell phone as a "hot spot" in my house (under TMobile's Magnenta 40GB plan) it is useless. It's not strong enough for other devices to use. In other words, I can't use a Chat on a website using my iPad connected to the iPhone's signal. Website pages take 4 minutes to load, or perhaps never load. 

If I use my cell phone as a "hot spot" in town, the signal is strong enough to share with my iPad. I can chat, download, upload, stream shows, etc. So I know my problem isn't my devices. The problem is the signal strength that I am able to get inside my home. Hence my need for 2 outdoor external antennas- one for the Acadyan and one for the cell phone.

I understand its congestion and beyond my control. 

For the most part I can get things done during non peak hours. What I can't do is use the Arcadyan's SSID home internet on weekdays between 9am-5pm to do things on my computer or iPad. Things like check email, log into an account, reset passwords, download transactions or chat with support. For example, I've been trying to type into this window 3 times. The connection keeps dropping. It finally came up to 2.18mbs so hopefully this post will go through now.
