Internet Connection Is Unreliable Computer Problems & Solutions
Problem: Internet Connection Is Unreliable
Solution: Unreliable or intermittent Internet connections are usually the result of a hardware or signal problem at some point between your PC and the web.
Some of these problems you can fix, others may require a service call from your ISP.
The first thing to try is resetting your modem and router and swapping out the network cables between them. Kill the power to your modem and router, wait a few moments, and then power them back up.
Also, be sure to use known good cables to connect the devices together.
We can’t count how many times a faulty cable has caused funky issues on a network.
If the problem persists, give your ISP a call and have it run a diagnostic to check the signal strength and quality on your line. Should your ISP find a problem, odds are it can be fixed by a service technician.
