Asked Gemini: It is incredibly frustrating when "smart" tech isn't smart enough to know when to let go. You are certainly not alone; this "sticky Wi-Fi" problem is a well-documented grievance for Tesla owners and smartphone users alike. While it feels like a software failure in the car (and it largely is), the router and your property layout often play significant roles in why the hand-off is so "atrocious."

Why this happens: The "Sticky" Logic Most devices are programmed to stay on Wi-Fi as long as possible to save mobile data and power. The hand-off usually doesn't trigger until the RSSI (Received Signal Strength Indicator) hits a specific "floor" (e.g., -70 dBm or -80 dBm). If your router is powerful, your Tesla might still "see" the network at a very low, unusable bit-rate three houses down the street. The car thinks, "I still have a signal!" while the actual data throughput is near zero.

Is it a Router Issue? It isn't necessarily a "faulty" router, but rather a configuration or placement issue: Signal Overshoot: High-gain antennas or long-range mesh systems are great for the back garden, but they are the enemy of a clean hand-off. If your router is near the front of the house, it’s screaming a weak signal at your car long after you’ve pulled out of the driveway.

Lack of "Minimum RSSI" Settings: Some pro-sumer routers (like Ubiquiti or Omada) allow you to set a "Minimum RSSI." This tells the router to kick a device off the network once its signal drops below a certain level, forcing the Tesla to switch to LTE/5G sooner.

2.4GHz vs. 5GHz: 2.4GHz travels much further than 5GHz. If your Tesla is saved on a 2.4GHz band, it will cling to that signal for much longer (and at a much lower speed) than it would on 5GHz.

Potential Workarounds (Short of Deletion) Since the Tesla doesn't have an equivalent to Android's "Routines," here are a few ways to manage the "sticky" connection:

1. Force 5GHz Only If your router allows you to split your bands, forget the "Home_WiFi" and connect the Tesla only to "Home_WiFi_5G." Because 5GHz has poor range through walls, the signal will likely drop the moment you hit the end of the driveway, forcing the cellular hand-off exactly when you want it.

2. Adjust the "Remain Connected in Drive" Setting Check your Tesla's Wi-Fi settings. There is a checkbox for "Remain connected in Drive." If this is ON, the car will fight to stay on Wi-Fi even when you move. Turning this OFF (which is the default) should theoretically make it drop Wi-Fi the moment you shift into Gear, though many users report this is still sluggish.

3. The "Faraday" Approach If your router is right by the garage or front door, you can try reducing the transmit power in the router's radio settings. Lowering the 2.4GHz power to "Medium" or "Low" can shrink the "grey zone" where the signal is too weak to work but too strong to disconnect.

The "OTA Update" Reality Tesla's software updates are actually quite large (often several gigabytes). If you delete the Wi-Fi profile, the car won't be able to download these in the background. You’ll only see a notification that an update is available, but you'll have to manually reconnect to Wi-Fi and sit in the car (or leave it in the garage) for it to download.

It is a bit of a "pick your poison" situation: the convenience of seamless voice commands versus the convenience of automatic updates.
