Just changed from Spectrum to T-Mobil home internet. All devices work just fine on the new network except my wife's 2017 MacBook Pro 13". Won't stay connected for more than 2-3 minutes then disconnects.
MacBook Pro 15″, macOS 13.7
first be sure to "forget" the old network, so that you are not trying and failing to connect to it.
Wi-Fi Radio Signals from your Router fall off as the inverse square of the distance. Provided you are close to your Router and have clear line of sight and no competition from neighbors' Routers or known interference producers like microwave ovens, you should not be having issues.
All others need to do a more careful analysis to find out what is happening.
Wireless diagnostics:
Hold down the Option key while you click on the Wi-Fi icon on the menubar to open up the tools for investigating and fixing Wi-Fi issues
Choose "Open Wireless diagnostics", which opens the wireless diagnostics Assistant, but does not proceed.
NB> Wireless Diagnostics is an App that puts up its own MenuBar.
Using its Window menu, there are about eight different things you can do from here,
Assistant (default window)
Info
Logs
Scan
Performance
Sniffer
Sidecar
Diagnostics
The top-level is to choose Diagnostics off the Window menu, or simply click (Continue) to do a quick check for Gross misconfiguration or operating problems. Your Admin password will be required. If any recommendations are shown, you should consider then seriously.
Next is to hold down the Option key and click the Wi-Fi icon as before. The screen that opens shows operating parameters of your Wi-Fi network. There is a great deal of valuable information in those numbers.
Readers are eager to interpret what is going on from the values there. Screenshot, transcribe, or photograph the results and post back in a reply on the forums. Looks like this older one.

In addition to the Wi-Fi info requested earlier, remove all add-on VPN apps, and all add-on security apps, restart, and test again.
