========================
Detailed description：
Hi, I’m having a lot of WiFi issues with a new ASUS TUF Gaming A15 FX506II running windows 10 64bit.
The laptop came preloaded with a “Realtek 8822ce wireless lan 802.11ac pci-e NIC”
I will list the issues I’m experiencing below and also the actions taken so far to try and resolve (no success so far)
PROBLEMS:
- extremely slow to reconnect to stored SSID after restart. Often it will stall completely and fail to connect unless I manually disconnect from any stored SSID and reconnect OR switch WI-FI on and off from system tray (this may or may not work). Often I will have to let the laptop sit idle for up to 5-6mins and it will eventually reconnect to the internet (note windows Wi-Fi status shows a successful SSID + internet connection for all this time)
- intermittent (random) internet connection drops, where the system tray can show an active Wi-Fi + internet connection but all apps and browsers fail to connect (timing is random, every few mins or 10’s of minutes, but eventually it will happen)
- duplicate SSID Wi-Fi names appearing as an option to connect in windows available WiFi list. Where there is a “2” after appearing as a suffix to the SSID name. This one is very strange and bizarre. As an example, if my WiFi network is called “My_Home_WiFi_SSID”, it appears in the windows WiFi list as “My_Home_WiFi_SSID 2” and it will work with all apps connected to the internet. This is not an SSID my router is broadcasting!!

- Speed tests over 5ghz WiFi (with all conditions identical, same location, no other devices connected to AP, etc.) can vary massively from the max router bandwidth available of 250mbps to as low as 30mbps. In some case the 2.4ghz WiFi connection will get a faster connection then the 5ghz and several minutes later the 5ghz will return to 200mbps+
- As I understand it there are 2 radio antennas in these laptops and the ASUS software for controlling these antennas is called “Asus MultiAntenna Service”. This software is also recommended for download from ASUS support page when I filter based on my exact model. Unfortunately, the latest version of this software v204, from ASUS support page is corrupt and missing 2 files in the installation packet, resulting in errors during the installation. This is not a download issue as I’ve repeatedly downloaded this compressed file from a different laptop. The management service it tried to install still getting added to windows even with the install errors but the service will not start up when started directly from the windows service list. I’m assuming this could be at the route of the problem. See other attempts to resolve this below.


STEPS TO RESOLVE:
- There has been no recent changes to my router AP. All settings are the same and all other devices connected over 2.4 and 5ghz are working as normal with very fast and reliable internet connections.
- I tried installing the latest wireless NIC drivers from both the ASUS site and newer ones direct from Realtec. I also tried rolling back to original versions of the driver files offered by Microsoft.

- I have disabled the OS power management options at the driver config level in device manager
- As a test I tried changing the WiFi frequency and channel at the router side and removing security
- I downloaded an older version of the Asus MultiAntenna Service (v203 and v202). The missing files from the latest version (v204) are present in these install packages and there are no error messages during the install but the service continues to throw an error when I try to start it manually in the windows service manager.
The laptop is brand new.

I am having the same issue. It's intermittent (internet disconnects every 2-10 minutes). The windows network diagnostic troubleshooter shows multiple different issues. I had the laptop for about 2 months before it got this bad.
I did the BIOS upgrade, checked the drivers, pretty much everything else I found online as well (almost all of the things OP has tried).
I guess the last possible solution is to return it to Costco. Thanks OP, for going through this first and posting it online so I don't have to waste as much time as you.
