[SOLVED] Why do PCIe wifi cards not work with this motherboard?

[Yoiji]

I have the Asus Rog Strix Z270e. It has a built in wifi card that gets 100 percent signal strength but the ping is always high. I bought over 8 different PCIe wifi cards. Each one gets 88 signal strength and the ping is amazing but I get lag spikes. It is like the motherboard is bottlenecking the PCIe wifi card. I did disable the built in card in the bios to see if that caused any issues and the problem is still the same. Does this motherboard just only work with the internal wifi card and just is sensitive to the PCIe cards? Is there a way I can take the built in wifi card out and replace it with an Intel chip? I used Netsh wlan show interface on CMD to test the signal strengths.

Are you certain that there is only one network adapter card (either wireless or wired - not both) enabled?

System hardware specs and OS?

Run Task Manager, Resource Monitor, and Process Explorer (you may need to download Process Explorer) to observe system performance. Use one tool at time under varying conditions: system idle (you are doing nothing), light work (browsing, typing a document), and lastly gaming.

Make and model router?

Have you tried a wired connection - may not always be convenient but a temporarily run ethernet cable from pc to router may provide additional insight: e.g., do the lag spikes continue?

Besides ping try pathping and tracert.

Run and post the results of "ipconfig /all" (without quotes) via the command prompt.

So this is a 200 series board. So why does my device manager have Intel R Chipset 300 series family SATA AHCI controller? That is a 300 series chipset not a 200. Will this effect the wifi in anyway? I run Windows 10 x64 bit. I tried using the Asus PCE55BT(Has an Intel AC8260 chip), I tried using the Asus PCE AC56. Each card was locked at 88 percent signal strength. Great ping with these cards but insane lag spikes. I only get a stable connection when I use the built in wifi card(100 percent signal strength) but it gives me horrible ping. @Ralston18

I see on this motherboard that it splits the PCIe lanes with the 3.1 USB lane? Is there a way to shut that off or does that not effect my wifi?

Not at all uncommon for a motherboard to have some component upgraded to a newer version/series.

Download, reinstall, and reconfigure the wireless adapter card based on the wireless adapter itself.

Go to the manufacturer's website and download the 300 series driver.

@Ralston18 So does the built in wifi card on the motherboard connect to M.2? If so, how can I disable the M.2 in bios so I can just have the motherboard focus on the PCIe slots? If the built in wifi card is not plugged into M.2, how can I disable whatever port it is connected to?

 

[Ralston18]

M.2 is a form factor for SSDs.

Apologies but I am not following what you are describing with respect to M.2, PCIe ports, and network adapters.

Overall, you should be using "WIN" + "I" > Network & Internet > Status > Change adapter options to select and configure network adapters.

Are you able to run and post the results of "ipconfig /all" (without quotes) via the command prompt?

The results will help with understanding how your computer is current configured for networking.

(I just plugged in the Asus PCE 55 wifi card which has a built in Intel 8260).

I am asking what slot does a built in motherboard wifi card fit into. What does the built in wifi chip plug into? Because I want to turn that off to hopefully have the motherboard focus the bandwidth on the PCIe slots. @Ralston18

The wi-fi adapter should just be a pcie header adapter so that instead of going into a mini-pcie slot on the board it's mounted at the rear i/o. If you wanted, you could very likely unscrew it from the bottom of the board and open the metal covering to replace the wi-fi adapter in that with the asus wi-fi cards adapter you just added. You would need to remove the plastic shrouding first. You will also need a tool kit for cell phones or some other small devices, because the screws are very small.
