Thanks for your reply. All the internet will be used for in the receiving building is TV and of course to surf the internet. No gaming or large downloads. So, will the M2's work okay? Also, you mentioned a computer to run software (AP), don't they all need that to set them up? Or, is a computer needed for something all the time? I have set one of these up before, about 10 years ago, with some now old style antennas. I am not an expert at it. I just am able to figure things out. I appreciate your input.
How are you receiving the TV signal? From the carrier? If so, you wont be able to distribute their signal without utilizing their equipment. Also, video eats up lots of bandwidth. AT&T uverse distributes their TV wirelessly with 5G APS.
You will want the nano M5 ACs if you are distributing video signals. They have far more bandwidth than the older M2s.
As to setup, you only need a device with a web browser to setup the nanostations.
The Unifi equipment needs either a controller dongle or controller software setup on a computer. This is for initial setup and for any changes or logging you want.
Sure you could set them up one time with the software controller and then not run the controller anymore but then you wont be able to make changes or troubleshoot without having the controller software running. The dongles are great for this. They also give you remote access via the ubiquiti portal or app on the phone. You could setup remote access to the software controller but it can be finicky especially on a machine used for other stuff.

I have 2 M2 Nano stations that a guy set up for me, They are about 100 Ft apart and I have both of them in a window as I have not mounted them outside yet. I have both plugged into routers without any special configuration I just plugged them in.
yes the nanostations can be programmed with any network connected device. But the Unifi equipment is different and requires a hardware or software controller. 2 different animals. One cannot program Unifi equipment WITHOUT the controller. The conversation is mixing up different technologies from the same company.
I get a 2G and 5 G signal at my shop with these. A speed test gives me on 5 G about 25MB and 2 G about 12 in my home I get over 400MB on my 5G. It is enough for what I need out there but more is always better. I can not get into the settings as the guy who set them up does not remember the password and it is not factory. I am happy with them and may try moving them outside and maybe that would up the signal but I am not sure.
If you switch those nanostation M2s to nanostation M5 ACs you will get close to 400Mbps in your shop. The M2s are limited to 100Mbps because of the 100Mbps NIC interface on them. The M5 AC radios have 1Gbps NICs. Also, you should be getting more than 25Mbps. Sounds like they're not aimed very well. Keep in mind, glass will attenuate the microwave signal. These radios are designed for line of sight with no obstructions
In regards to getting into the settings, you would need to factory reset them. There's a small pinhole inside the door where you can stick a paperclip and reset the radios to default. Then just need to reprogram them.
