The Ethernet connection is not functioning properly.
The Ethernet connection is not functioning properly.
I added a 1GB NVMe SSD to my system alongside the 2.5GB NVMe build into my M.2 MEG motherboard for testing dual Ethernet ports. After removing the card, it won't work at all—Bios shows it, Windows doesn’t detect it, and MSI drivers can’t see it either. I’m currently using the built-in Wi-Fi, though I’ve tried turning it off.
Windows 10 is experiencing networking problems. I’m curious if we can force it to function again. Did the 2.5Gbit port operate correctly when the 1Gig NIC was connected? It seems Windows has set the AIC as the main interface and now it’s disregarding the onboard one. Does the onboard interface receive an IP address? Can I send a ping to the router?
Can you keep one NIC active while installing just one driver? What happens to the other? Usually, you shouldn’t have more than one interface on the same network, except for specific server needs.
I connected the second Nic adapter to the same 8-port switch. It didn’t work at all—neither appears in Windows or Device Manager. I uninstalled both driver versions and reinstalled them one by one, but the onboard driver still failed with an error about no Realtek controller found. Reinstalling only the Nic drivers fixed nothing.
Setting the NIC to disregard DHCP isn't a problem. If they lack a driver, it'll appear as Other Devices. You can manually configure the driver via Device Manager, though effectiveness depends on your setup. Have you checked whether Windows Updates might help?
You can locate either the NIC and configure its driver within Other Devices. Often, you direct the prompt to the NIC driver you saved from the manufacturer. It uses a bit of space but likely relates to Layer 2 communication. Layer 3/4 should be functioning properly.
