Method 8: Make Sure Your Firmware is Updated To Latest Version

Sometimes outdated firmware settings do not let you enjoy a smooth Ethernet connection. This is exactly why you need to keep the firmware updated on all of your devices.

For Example: modem, router, or repeaters.

Find their firmware updating instructions online from OEM and update them all to their newest versions.

Method 9: Update or Reinstall Your Network Adapter Driver
