Realtek 8822CE causes issues with your Wi-Fi router
It appears the Realtek Wi-Fi card in your laptop is causing instability on the 5GHz band when routers are set to Auto Mode. When manually selecting channels, the problem disappears. All power-saving settings in the adapter properties are disabled. If the router stops broadcasting at 5GHz and no devices recognize its SSID, the issue likely stems from the card itself or its configuration. Your Intel Wi-Fi card functions well, and the Realtek model (Realtek 8822CE) is compatible with TP-Link Archer C6 V2.0. The laptop you’re using is a newer Asus model, which may also contribute to the behavior.
When you mention “crashing,” it means devices that were previously linked can stop connecting. You should manually adjust your wireless channel. Relying on the router to pick a channel automatically often leads to this issue. The auto feature lets the router decide based on nearby signals, which can cause frequency overlap and interference. Sometimes it selects a channel not recognized by certain adapters. I’ve noticed that using channels near the center of the 5GHz band works better, but some devices can’t see the SSID anymore. Switching to a channel at the extremes fixed my problem. Intel adapters usually handle this without trouble.
Refers to the 5GHz network disappearing from all devices—TV, PC, phone—and suggests replacing it with an Intel chip, which Asus handles automatically when you open the laptop without warranty.
There must be hidden deals since HP, Lenovo, Dell, and Asus know about this problem. MSI relies on Intel in many of their laptops.
The adapter doesn't handle the 36 band at 5GHz. I changed it to 44 and will revert to 3 manually to verify.
