How to Fix network switch Driver Issues in Windows 11

Quick Answer

To fix network switch driver issues in Windows 11, open Device Manager, find the unmanaged switch's network adapter under Network adapters, right-click and choose Update driver. If that fails, uninstall the device, reboot, and let Windows reinstall the latest driver automatically.

Why Your Switch Driver Plays Up on Windows 11

A network switch itself doesn't usually need a driver, but the bridge or NIC linking your PC to the switch does. After a Windows 11 feature update, drivers for Realtek, Intel and Killer NICs often roll back to a generic version, which is why ports drop, speeds throttle to 100Mbps, or the LAN icon shows that yellow exclamation mark. Sorting it locally beats waiting two weeks for a courier swap.

Step-by-Step Driver Refresh in Device Manager

Press Windows + X and pick Device Manager. Expand Network adapters, right-click your Ethernet controller and select Properties, then check the Driver tab. Click Update driver, choose Search automatically, and Windows will pull a fresh build via Update. If the date stays old, hit Uninstall device, tick Attempt to remove the driver software, reboot, and Windows 11 will reinstall a clean copy on boot.

When You Need the Manufacturer Driver Instead

Windows Update sometimes serves a generic driver that hides full Gigabit speeds. Visit the motherboard or NIC manufacturer's South African support portal, grab the matching Windows 11 24H2 build, and run the .exe as administrator. For TP-Link, D-Link and Mercusys gear bought through Evetech, the bundled CD or official site has the latest .inf file. Reboot once after install and your switch should renegotiate at full link speed.

Switch-Side Checks Before Blaming Drivers

Swap the patch cable, try a different port on the switch, and if you're on a managed switch log in via the web GUI to confirm port status is enabled. Loadshedding spikes can corrupt switch firmware, so a 30-second power cycle through your UPS often clears phantom faults that look like driver issues. If your home setup keeps tripping, a small router upgrade fixes the upstream side too.

Frequently Asked Questions

Does a network switch need its own driver in Windows 11?

Unmanaged switches are plug-and-play and need no driver. Only your PC's network adapter and any USB-to-Ethernet dongles connected to the switch need driver support inside Windows.

Why does my switch port show 100Mbps instead of 1Gbps?

That's almost always a driver mismatch or a Cat5 cable. Install the manufacturer NIC driver, force 1.0 Gbps Full Duplex under adapter properties, and use Cat5e or Cat6 patch leads.

Will uninstalling the driver wipe my network settings?

No. Your IP, Wi-Fi profiles and saved networks live in the Windows registry separately. Reinstalling the driver brings the adapter back with all settings intact.
