dual 5g internet use

Bobcat2591…..

I’m using two boxes because of a bandwidth concern. So far reliable enough and only $60 p/month for both boxes. I’m also very limited where I have an acceptable signal. The current box locations are the only locations with at least a “good” signal. This spring and summer after the leaves are in full bloomwill prove if the signal will continue to be strong enough for usability. I have considered a signal booster, not a wifi booster. I don’t completely understand the concept though and that may be the most feasible option if signal boosters actually work. My only internet options are either T Mobile or Verizon. 
Thank you

@TSully, I'm surprised you could get what you've described to work. By splitting the 2.4 and 5 GHz bands, you probably worked around the problem of having DHCP on two different devices.  Duplicate DHCP servers will cause havoc on your network, and unless you can stop the Verizon box from also serving up IP addresses, you'll have problems. In addition, unless you can configure the Verizon box to be in the same IP range that the T-Mobile devices are assigned (192.168.12.x) you will also introduce problems into your network.

I would think a simpler and less expensive setup would be to move the T-Mobile gateway upstairs to the best location you can find, then use network extenders to cover the areas of your house that need coverage. I also like @copz1998’s suggestion of a mesh network. I use one Netgear N300 in a part of my house that is a bit of a dead zone, and it works perfectly. Any WiFi extender will work, and you can use more than one, if necessary. As an ex-network exec, that would be the architecture I'd choose rather than what you're proposing.

Let us know how it goes! Good luck!

COPZ1998……. I’m thankful for your input. I’m currently using two T Mobile 5g internet devices. One is placed in a location about 12 feet from the other. Separated by a floor. One is set on the 2.4ghz and the other is set on the 5ghz. I did seem to have issues when I first set up the internet boxes and they were on the same wi-fi bands. I have half my stuff set to one box and the other half set to the other box. So far both seem to work, albeit some occasional quirks, and I’ve been doing this for about 6 or 7 months. I’m very aware of potential issues arising from tower signal degrading in the springtime when the leaves bloom on the trees. I’m trying to prepare and/or prevent that issue from happening again. I’ve gone to the extreme of removing trees to help clear a path for the signal. Hence the potential use of a Verizon 5g internet box.
The Verizon signal comes from a different tower than the T Mobile signal.

So I already am aware two T Mobile 5g internet boxes will work. 
What I don’t know is if the T Mobile 5g internet and the Verizon 5g internet will interfere with each other. Your provided link above didn’t address my specific concern or I didn’t recognize that it did when I read the article. 

Thanks again!

@TSully I am a T-Mobile user and am not sure why you would want to add a Verizon gateway. Do you want better coverage in your house/workplace? If you want better coverage you would be better off adding a wifi mesh system. You would use one gateway that is plugged into your mesh system, and the devices would connect to the mesh wifi. I am using the Netger MR60 mesh wifi and get over 100Mbps all over both floors of my home. 

Yes, both systems (T-Mobile and Verizon) will step on each other; the 2.4 and 5Ghz broadcasts will step on each other. 

Here is an article that discusses the issues: https://smarterhomeguide.com/setting-up-2-wifi-networks-in-one-house/

I hope this helps!
