What are the signal and noise levels as reported by macOS? Option-clicking the WiFi icon on the menubar will reveal these details. The signal strength is called "RSSI" and should be somewhere between -35db to -65db (-65db is a weak signal so will have a slower transmit rate). The Noise level should be somewhere around -90db or -95db.
I have seen software issues affect the WiFi connect on macOS so that is another possibility. Try booting into Safe Mode to see if there is any difference, although I've been informed by a respected forum contributor that Safe Mode may no longer be as effective at preventing third party software from launching automatically due to recent changes in macOS 13.x Ventura.
You can try using using this Apple article for troubleshooting WiFi issues:

You may also want to power cycle the router. Perhaps even test when this laptop is the only device connected to the WiFi in case other devices are interfering.
Is the laptop display open or closed? I have seen people mention that they have WiFi issues when the display lid is closed as the antenna contained within the built-in Display Assembly which is not optimally oriented when closed.
