I have had my Teracube 2e for 2 years, never used it much at all. Now I am trying to use it.
My issue is that it will not give me access to my Wi-Fi internet at my office, but it does at home.
I have AT&T telephone and internet service at both locations.
When I log on to home Wi-Fi, I have internet access.
When I log on to office Wi-Fi, it says no internet available. HOWEVER, I have 2 other phones and both of those can/do access the internet through my office Wi-Fi.
What do I do to fix this issue?

Have you maybe set a static IP address for the network which does not work on your office internet? Might there be a proxy or other setting which is different between the two locations? Are they named the same or something different? Is there a chance that the work internet is using MAC filtering and your device is using the default setting to rotate to a different MAC address, so even though it was allowed by the administrator once, it fails on any future connections?
There’s a lot of different possibilities, but it’s hard to guess precisely why it fails without full information. Due to it working at home for you though, that means it’s not an issue with the hardware itself, but something about your configuration, whether on the phone or the network infrastructure (router or wireless access point).

Thanks Maymne, I will look further, this is getting beyond my techie knowledge/ability 
I am guessing it is through a proxy server here at the office and not at home, but there is nothing in settings on any of my 3 phones that appears “different” and 1 connects without issues, 1 connects without very many issues and the Teracube 2e connects to my Wi-Fi but says “no internet available on this connection”

Yeah, unfortunately it’s really hard to guess what might be the case. If you’re on Android 13 and go into the saved networks area of wi-fi, I’d compare the advanced settings by clicking on the edit pencil in the upper right, going to advanced options, and verifying metered/proxy/ip settings/privacy between your working and non-working devices.

Hey Maymne
Thanks…I tried that and every setting appears to be the same on SAMSUNG as on Teracube 2e EXCEPT the IP Address, but I can not change that…I tried. On the SAMSUNG a QR Code pops up on settings and says “Scan this QR Code on another device to connect to office without entering password” but I cannot figure out how to make the Te2 scan the QR code. Any ideas on how to do that? I do not think it will help as I am already logged in to office wi-fi, I just can’t access internet with the wi-fi link. 
To connect using the QR code, remove the old network configuration - disconnect from the network if connected and then remove it from Saved networks. After it’s gone, at the bottom of the Wi-Fi area, below the available networks, there’s a line with:
+ Add network | QRCode+
If you click on the QR code with the plus on the right side of that line, it should bring up the QR scanner to allow you to connect using the QR code from your Samsung.
Note that the question about the IP settings was to make sure you were using the same method - they should probably both be set to DHCP, not the same. Only one device on a network can use a specific IP address at any one point in time. If you manually configure your Teracube to use the same IP address as your Samsung, and you configure MAC spoofing to pass that validation as well, and you shut down both devices and then turn on the Teracube, then your Teracube will probably work but the Samsung won’t after it powers up. Not something I’d recommend doing.
Did it, it did not work. I get the same “no internet available” error.
Thanks anyway.
Yep, if there’s network MAC filtering on the backend, you’d need to allow that through the router’s allow list, rather than anything actually being wrong on the phone side. Problem is that’s based on whatever control OS is in use there, rather than anything we can predict here.
