Persistent connectivity problems with the onboard Realtek 2.5GbE interface have puzzled you for a while now.
It seems everything functions properly with the stock version. Have you attempted to update the audio driver? Additionally, consider adjusting the power plan, as these changes are often linked to DHCP issues.
Alright, if you keep using the Windows 11 driver, it functions well but causes audio problems through NDIS.sys DPC latency. All other connected devices and drivers are updated and working properly. I’ve enabled high performance power plan, disabled USB suspend, and turned off PCI link state in Device Manager. I’ve also disabled power-saving features in the Ethernet driver and set “Allow Windows to turn off this device” off for all USB items. The issue seems linked to a Realtek driver—especially when switching to the built-in Windows driver for the Ethernet card. The internal network card and external type C card are stable, but the problem arises only with the Realtek-based NIC after installing its driver. It’s frustrating, especially since the external card works without issues.
You might already have attempted this, but it wasn’t listed. Have you considered reserving an IP address for the NIC on the router? Since restarting the computer within an hour isn’t a concern, I’m curious if the router is struggling to assign a fresh internal IP after releasing it. Setting aside one for that NIC’s MAC address would eliminate the need for reassignment, making the connection feel seamless.
I'm pretty sure I used it on the old router, but haven't tested it with the one I recently bought. My old router was around 10 years old, even though the PC is performing the same tasks now. I'll try setting a reserved IP on the new one and let you know if that fixes the problem later today. Thanks for your help!
I received a notification. Unfortunately, locking the IP on the router didn't resolve the problem. After restarting the device, it briefly connected to the internet for about five minutes before disconnecting. This is my third restart attempt, and so far everything seems normal with network performance. I'm still trying to figure out what might be causing this issue.
I thought it was time to share another update. The problem has been fixed by purchasing a new motherboard. I received the same model I initially had, but the X870E version because it supports two chipsets and offers improved USB functionality (which is important for me). Up until now, everything has run smoothly and the internet works perfectly. I also noticed the system feels faster compared to the previous setup, which makes me think the motherboard might have been the source of the issue. Regardless, I’m grateful for all the advice and support from everyone. Thanks!
