Question Wi-Fi Issue with Asus laptop ?

[jimbo_pch]

Laptop: ASUS ROG Zephryus G16 Gaming Laptop (2024)
16" OLED QHD 240Hz
Intel Core Ultra 9
32GB LPDDR5X
NVIDIA RTX 4090
2TB SSD - Eclipse Gray (Model: GU605MY-G16.U94090)

Laptop is brand new and fully updated. Works beautifully when operated by itself (i.e. no external monitor, no use of keyboard/mouse dongles for connectivity).

If a peripheral is connected (e.g. external monitor, keyboard/mouse dongles for connectivity), Wi-Fi gets disconnected . . . "Solution" : Change Intel Network Adapter value to 5ghz... However, Wi-Fi signal is weak/unstable. I can only pick one peripheral to use... For example: I've connected an external monitor and switched keyboard/mouse connectivity to Bluetooth. Great. Now I want to play GTA V (which requires network access)... Connectivity to the game (when it works) is as skippy as the peanut butter... very much unplayable.

I've troubleshot everything, reset adapters, uninstalled/reinstalled adapters, reset the PC twice... No solution.

Took it to Best Buy Geek Squad (since I purchased it from BB)... They have a special "Geek Squad" Wi-Fi that runs on 5ghz. From the tech's words... If my laptop is not displaying their Geek Squad Wi-Fi as an available network, then something is most likely wrong with the hardware itself... It was displaying their Geek Squad W-Fi intermittently, which told them something was definitely wrong with the hardware.

So... my current situation... I've opted to exchange my laptop for a new one in hopes that this remedies the issue. I'm posting here because I really don't believe this should be an issue on a brand new $3k laptop. And I have a creeping feeling that the issue will remain on the new laptop. Not sure if an upgrade from Wi-Fi 6E to Wi-Fi 7 would help at all.

What am I missing?

What am I missing?
nothing, hardware can be faulty, even at high prices. That´s why you´ve got warranty.

BIOS was updated? Windows wifi driver as well as chipset?

Would use an ethernet cable nontheless

which exact peripheral did you connect and to which port on the laptop?
which wifi router are you using and how far away is it?
Is the router´s firmware up to date?

Kinda strange they swap the whole laptop in most laptops you can just replace the wifi card. Depends on the laptop and how hard it is to take off the back but some you can swap the wifi card out in 5 minutes. Defect wifi cards are not common but they do happen.

Likely the reason 2.4 has issue when you are using bluetooth devices is they both run on 2.4g. The generally don't interfere but they can. Both the bluetooth signal and the wifi signal are done by the same wifi module.

First wifi6e key feature is it runs on 6ghz. If your router does not run on 6ghz then it doesn't matter. Wifi7 is mostly marketing. It can run faster but wifi6e when working properly already is as fast as most people internet connection. Internet/wifi bandwidth is mostly marketing to get you to spend money for big numbers. Sure you get a faster speedtest but in daily usage it makes no difference. Things like netflix 4k video only uses 30mbps and having more makes no difference it still only uses 30mbps. It only really helps if you do massive downloads. How often do you reinstall something like microsoft flight simulator that is 100gbyte. How many minutes do you save in a month and how much per minuted saved do you pay.

Well, considering the problem could also be a defective antenna which would require disassembling the screen, I can kind of understand why they'd just swap it out and let the vendor deal with it rather than faffing around with troubleshooting parts.

If you still have the problem and need to use 2.4GHz, note USB 3.0/USB 3.1 Gen 1/USB 3.2 Gen 1×1 operate at a signal frequency of 2.5GHz and will badly interfere with 2.4GHz wifi unless all cables are extremely well shielded.
You could try wrapping the cables with metal foil tape (that's how they do it internally in routers with USB 3.0 ports!) or if you don't need particularly high USB speeds, a USB 2.0 hub to connect all of your USB devices through. That operates at 240MHz which will not interfere at all with 2.4GHz wifi.

All modern versions of Bluetooth since v3.0 +HS in 2009 only use the Bluetooth link for negotiation and establishment, then actually transfer the data using 2.4GHz wifi, only it's called "Bluetooth High Speed." And since it's not like your wifi card has a separate radio for that, it will be on the same channel as your 2.4GHz wifi is set for. While technically that should not interfere, a mouse with the ridiculous 4000 or 8000Hz polling rate so fashionable nowadays could sure hog all the bandwidth with so many small and high-priority marked packets.

If you thought range was poor on 5GHz, know that 6GHz is even worse as they have the same 30dBm radiated power limit but the higher frequency will not penetrate barriers or reflect as well so is even more line-of-sight dependent. The best solution would be to move your router closer to where you use your laptop, or to add access points so you could actually use the 5GHz.
There's no getting around it--for top performance out of 5 or 6GHz you'll likely need an AP in each room you want that in, depending on how solidly constructed and filled with stuff your home is. That of course is pretty inconvenient to set up, which is why the marketers are peddling all those convenient but expensive MESH systems lately. Sure performance isn't as good and you are polluting the airwaves with backhaul channels, but there's no wiring to run and your client won't actually drop so long as a satellite is nearby.
