Adding a second gateway

Yes you can but you will be paying $100 per month for 2 lines. In fact I had this happen to me by mistake. I was calling TMO to complain about my Nokia gateway not working and they agreed to send me the newer Arcadyn. I thought all was good until I saw a new phone number added to my account and another $50 charge. When I called to ask WTF, the rep looked into it and explained to me whoever arranged for my router replacement accidentally set the replacement up as a new line. Had I not called to get this fixed, I would still be paying for two lines of home internet. I actually thought about keeping it and finding out if I could somehow bond the two lines for almost gigabit speed, but it is not possible.

For others wondering how this was resolved, it took some effort. My original line could not be changed without fees since it was past the 15 day free trial period. I had to swap the SIM card from my Nokia gateway with the Arcadyn. This way I could cancel my “new line” at no charge since it was within the 15 day free trial and ship the Nokia with the “new” SIM card back to TMO. They sent me a prepaid shipping label so I did not have to pay anything. Did take an hour of complaining on the phone tho.

Confused.  You should only need the single gateway, with everything else handled by the mesh.

Rogracer2000, those were my thoughts also, but after having this service a little over a month and moving the gateway to every window in my place, that’s the only solution I can come up with. When you call customer service, all they tell you is to move the gateway. 

@F-150, your cellular metrics are excellent. I don’t believe they can get any better.  I wish I had cellular metrics half as good as yours.  I’m puzzled why your Wi-Fi signal is not reaching your devices. I am not familiar with the Google Nest routers, so I don’t have any suggestions on how to improve your Wi-Fi signal.  I have a TP-Link Archer AX21 connected by Ethernet cable to my Arcadyan 5G gatweway and none of my devices have any internet issues whatsoever.  Maybe someone in the community can pitch in and offer suggestions.

I hate to say this, but it seems like your Google Nest system isn’t functional.  Are you sure you are connecting to it and not just the gateway (which may be far away?).

A couple of things.  When you set up your Mesh system, you should set the SSID (network name) to something other than what the Gateway is using.  Then, on your remote devices, it will be obvious what you are connecting to.  If everything is running the same SSID it can be quite confusing.  Some people go further and make unique SSIDs for the 2.4 and 5 G Hz bands, so they have even more control.  Also, make sure your Mesh system is in “Access Point” mode.  Lastly, you can download a WiFI analyzer for your phone which will help you see what the various devices are broadcasting and their SSIDs.
