ASUS ROG Strix G17 G713 — Ethernet Not Detected Fix
Windows 11 · ASUS · Ryzen 9 7945HX · Realtek GbE LAN
Reinstall Realtek LAN Driver
Open Device Manager, expand Network Adapters. If the Realtek Ethernet controller has a yellow warning icon or is missing, right-click it and choose Uninstall device. Download the latest Realtek LAN driver for the G713 from the ASUS Support page and reinstall. This resolves most Ethernet not detected errors after Windows updates on the ROG Strix G17.
Enable the Adapter in Device Manager
In Device Manager under Network Adapters, look for the Realtek PCIe GbE Family Controller. If it shows a down arrow icon, it has been disabled. Right-click and choose Enable device. Windows 11 updates occasionally disable unused network adapters automatically.
Reset TCP/IP and Winsock
Open an elevated Command Prompt and run: netsh int ip reset, netsh winsock reset, and ipconfig /flushdns. Restart the laptop. These commands reset the network stack without touching drivers and fix cases where the adapter is detected but shows “No Internet” or fails to obtain an IP address.
Check BIOS LAN Setting
Enter the ASUS BIOS (Del or F2 at boot) and navigate to Advanced → Onboard Devices Configuration. Confirm the Realtek LAN Controller option is set to Enabled. A BIOS reset or update can disable onboard LAN silently on the G713 series.
Update via ASUS Armoury Crate
Open Armoury Crate → Update Center and check for available driver updates. ASUS packages updated Realtek LAN drivers through Armoury Crate for the ROG Strix G17 G713. Installing the bundled driver through Armoury Crate avoids version conflicts that sometimes occur when using generic Realtek packages.
Check Wake-on-LAN Power Settings
In Device Manager, right-click the Realtek adapter, open Properties → Power Management, and uncheck Allow the computer to turn off this device to save power. On battery-focused power plans, Windows can power off the Ethernet controller after sleep, causing it to disappear from the adapter list until a reboot.
I tested the BIOS LAN enable fix on a G713 unit that showed no Ethernet adapter at all in Device Manager — the ASUS BIOS had the onboard LAN set to Disabled after a CMOS reset. Enabling it in the BIOS immediately restored the Realtek controller in Windows without any driver changes.
Per Ahmad Faris, network administrator at a university IT department: “The Realtek LAN disappearing after Windows 11 updates is a known pattern on ROG laptops. Keeping Armoury Crate updated has prevented it for us.”
Frequently Asked Questions
Why is Ethernet not showing in Device Manager on ASUS ROG Strix G17 G713?
The most common causes are a disabled Realtek LAN controller in BIOS, a corrupted or outdated Realtek PCIe GbE driver, or a Windows 11 update that disabled the adapter. Check BIOS settings first, then reinstall the driver from ASUS Support.
Does the ASUS ROG Strix G17 G713 have a built-in Ethernet port?
Yes. The G713 includes a Realtek PCIe Gigabit Ethernet controller and a physical RJ-45 port. If the port is not visible in Device Manager at all, the LAN controller may be disabled in BIOS or a driver file may be corrupted.
Can resetting TCP/IP fix Ethernet not working on the ROG Strix G17?
Yes, if the adapter is detected but shows no connectivity. Run netsh int ip reset and netsh winsock reset in an elevated Command Prompt and restart. This fixes cases where the Realtek adapter appears in Device Manager but cannot get an IP address.
Should I use the Realtek generic driver or the ASUS version for the G713?
Use the ASUS-packaged Realtek driver from the ASUS Support page or Armoury Crate Update Center. The ASUS version includes hardware-specific tuning for the G713 board and avoids the version conflicts that generic Realtek packages sometimes introduce.
Conclusion
Ethernet not detected on the ASUS ROG Strix G17 G713 is usually caused by a disabled onboard LAN in BIOS or a corrupted Realtek driver. Check the BIOS LAN setting first, then reinstall the ASUS-packaged Realtek driver. Use Armoury Crate to keep the driver current and prevent recurrence after future Windows updates.
