Why is my Ethernet and Wi-Fi not working on a brand new motherboard and OS?

Oswin

Hiya, I just bought parts for a new pc build today and put it together. The motherboard is an Asus Tuf Z690 plus WiFi D4 with an I7 12th gen and Windows OS 11. Everything boots up great and is working. The only things that are not working are the Ethernet and wifi options. No lights come on when I plug in my Ethernet cables. The two cables that I have tested are working fine and have used them on my old computer. When in settings, the Ethernet doesn’t show it’s connected. Do I have to buy a USB adapter for this? I don’t want to have to do that since this motherboard is brand new. 

The wifi option is also not showing up at all. There isn’t a driver or anything for me to enable. I’ve tried the many fixes found on YouTube and in articles and forums. The only thing I haven’t been able to test is downloading new drivers from asus or microsoft due to not owning a flash drive. 

Is there something I am missing? Did I not setup the computer correctly or is motherboard defective? Do I need to download the drivers to see if this works (seems a bit crazy that I need to do that when this is brand new but I have no idea at this point)? 

Thank you for your help,

Right click on the "Start" menu and go to "Device Manager". Check if the device is listed under "Network Adapters". Also see if you have any devices missing drivers under "Other Devices".

Hiya,

I have opened device manager and the only network adapter showing up is the Intel Ethernet Controller I225-V. Under other devices, I have a whole list of items that are flagged (Network Controller, 4x PCI Device, PCI Simple Communications Controller, RAID Controller, SM Bus Controller, 2x Unknown device).

Double click on the i225-V. Does it state it's working properly?

Oswin

It does say it’s working properly.

@Oswin

Do you have another PC where we could download the chipset and other drivers then transfer it via flash drive? If so I would do that first. If you can't, try this.

From that properties window, go to "Advanced". Select "Speed and Duplex". Set it to "1.0 Gbps Full Duplex". Click "Ok" and restart.

I can download the drivers, not quite sure where to download from unfortunately. I will try that first and then the second if it doesn’t work.

Alright so I was able to get most of the drivers to work. The ethernet is still not working and now raid controller is being flagged under other devices.

@Oswin

That's the Intel Rapid Storage or IRST driver. What router/modem do you have?

Oswin

It is an AT&T router. It is made by Pace.

This particular adapter from my experience has serious issues with the AT&T Gateways. It usually won't connect to them at all, we'll need intermediary device. If you have a laptop with ethernet, you can run it through the laptops ethernet port and connect via ICS to verify the port is working. For a permanent solution, get a 5 Port Gigabit switch. They're usually under $30. Put it between the AT&T router and the PC, it'll work fine.
