-: In this section of the course,
we're going to talk all about how to troubleshoot
network issues including wired connectivity issues,
network performance issues, wireless connectivity issues,
VoIP issues, and limited connectivity issues.
So, as we move into this section
we're again going to be focused on domain five,
hardware and network troubleshooting.
But this time we're going to fully cover Objective 5.7.
Objective 5.7 states that given a scenario
you must be able to troubleshoot problems
with wired and wireless networks.
As we begin this section, we're going to first take a look
at different wired connectivity issues
like electromagnetic interference, distance limitations,
and things like that.
Then we'll move into some different network performance
issues such as slow network speeds, high latency,
and port flapping.
Next we'll move into our discussion of wireless connectivity
issues such as intermittent wireless connectivity,
signal interference, and slower than expected speeds.
After that, we're going to cover some issues associated
with voice over internet protocol services known as VoIP.
This includes poor voice quality, high latency,
and jitters inside of your communications.
Finally, we'll cover limited connectivity issues
and their potential causes so that you can solve
these issues and get your end users connected back
onto the network once more.
Now, as you're going to learn in this section of the course,
there are lots of different networking issues
that you're going to encounter as a technician in the field.
Our goal for you in this section of the course
is to help you become that first level of support
for some basic networking issues
that your end users are going to experience.
My goal is not to turn you into a full network technician
or network administrator because that is reserved
for the network plus level of certification.
Instead, you're going to be the first line of defense.
So let's get started with our coverage of how to
troubleshoot network issues in this section of the course.
