You have to go into your AT&T provided router/gateway and make a configuration change. How to do it depends on what specific manufacturer and model of equipment was provided.
Typically you would use a web browser and use the IP address 192.168.1.254 to connect.

Which gateway? Single band 2.4 GHz 510, 5031, 3600, 3800, 3801, i38hg?
Or A dual band 599 or 5268?
If dual band, which network name did you change, the 2.4 or the 5?
Note not all wireless devices support dual band, especially older laptops, wireless printers and smart phones that are inexpensive. I have a $150 Motorola that only supports 2.4.
If you changed the 5G name but your laptop/PC does not support 5G wireless, the device cannot see the new network name. Try changing the name of the 2.4 band, does it see now?

I cannot login to my network with the new name and password on my desktop because my desktop cannot see the network. Right now I am on my home network and everytime I go to http://192.168.1.254 it gives me the setup info for my home network. If my desktop cannot see the other network (office network) how do I know which band I changed. How can I access the office network using my home network? Do I need to reinstall my office network and start from scratch.

Okay, now you totally lost me. You have a "home network" and an "office network", so you have two routers or what are you talking about?
Refer to the image below and ignore the red 3 and 4:
On the line labeled Network Name (SSID) is where you change your network name.
Or are you talking about changing your network name on your computer? If so, are you running Windows 10 on your laptop?

Let me repeat back:
This has to be Windows 10. I'm just saying.
Step One: To connect to your network, click the network icon in the system tray and select from one of the available networks. Then, make sure you de-select the Connect automatically option because you want to be able to flip back and forth between your two WiFi networks.
Step Two: Reload your office desktop PC. DO NOT merely shutdown, as that will not reload Windows completely. See if that resolves the issue your are experiencing. I am thinking this may allow you to see the missing SSID. Select new SSID and go back to step one.
Point is you should not be automatically connecting to both WiFi because if you do Windows may switch from one to the other as one signal becomes stronger than the other.
Please refer to the following:
Since you state that you can see both WiFi networks on this panel, you may want to go here and de-select Connect automatically from here.
And finally, make sure that your Office router and the other router are using different channels so the signals don't interfere with each other.
