Solution 2: Update Network Card Drivers

If the network card drivers are outdated, you need to update them. Check the network card manufacturer’s website or the computer manufacturer’s website to see if there are updated network card drivers.

Then download and install the updated drivers and restart the computer. After that, check if you are using an unstable Internet connection.
