After connected to the T-mobile gateway, my computer could not find the Internet. Troubleshooting says: Wifi doesn't have a valid IP configuration. I tried the tutorial online to fix, but all failed. The computer can connect to Router or Hotspot without any problem.

If the answers to those question are “No” and “Yes”, you probably need to add a second SSID dedicated to 2.4 GHz. Let me know if you need instructions to do that.
If you were connected, but lost it, have you tried restarting both the gateway and the computer. And if you still can’t connect, try opening a command prompt and doing ipconfig /release and ipconfig /renew
