Acer Predator Helios Neo 16 will not connect to Wi-Fi or keeps disconnecting

The checks in more detail

Forget and rejoin the network, use 5 GHz by name and restart the router. Drivers matter for gaming laptops: a recent driver can cure a drop that began after a Windows update. A Bluetooth headset can disturb 2.4 GHz Wi-Fi, so use 5 GHz. Test on a hotspot to isolate the router. A Network reset rebuilds the adapters. If Wi-Fi and Bluetooth both fail the card may be faulty and Acer should replace it under warranty. The PCWorld review notes the laptop's strong hardware, which makes the network the usual bottleneck.

Gaming laptops use more power at the wall than the Wi-Fi card likes in a noisy environment, and a charger or a cooling pad with a poorly shielded USB hub placed beside the card can add interference. Moving the USB cables away from the area under the left palm rest, where the card sits, and unplugging USB 3 devices as a test, can fix an unexplained drop. Write down the Wi-Fi driver version and the date of the last Windows update, since a drop that began after an update points at the driver, and Acer's site lists the version that fixes known faults.

A rollback of the driver from Device Manager is a quick test: open the adapter, Driver, Roll Back Driver, and see whether the drops stop. If the network is fine on other devices and the laptop alone drops, consider turning off the adapter's roaming aggressiveness in its advanced properties and setting the preferred band to 5 GHz, since a laptop that hops between bands whenever signal changes will drop connections. Test for a day after each change so that you know which one helped.
