Now, let’s learn how to test Ethernet cables so that we don’t waste our time trying to figure out why exactly there are so many connectivity issues:

1) If Your Internet is Slow or if There Are Numerous Drop-Offs

This usually happens when the Ethernet cable is damaged or bent. The first thing to do is to test if the entire length of the cable. If it is bent in a place or two, simply straighten it and that’ll do the job. If it is damaged, you may have to take measurement tests for repairing or replacing it.

If you aren’t unable to figure out what’s wrong, then don’t test the problem yourself. Calling an expert would be the right way to go.
