<v ->In this section of the course,</v>



2

00:00:01.950 --> 00:00:04.020

we're going to talk all about how to troubleshoot



3

00:00:04.020 --> 00:00:07.050

network issues including wired connectivity issues,



4

00:00:07.050 --> 00:00:10.140

network performance issues, wireless connectivity issues,



5

00:00:10.140 --> 00:00:13.260

VoIP issues, and limited connectivity issues.



6

00:00:13.260 --> 00:00:15.270

So, as we move into this section



7

00:00:15.270 --> 00:00:17.610

we're again going to be focused on domain five,



8

00:00:17.610 --> 00:00:19.380

hardware and network troubleshooting.



9

00:00:19.380 --> 00:00:22.950

But this time we're going to fully cover Objective 5.7.



10

00:00:22.950 --> 00:00:25.950

Objective 5.7 states that given a scenario



11

00:00:25.950 --> 00:00:27.840

you must be able to troubleshoot problems



12

00:00:27.840 --> 00:00:30.150

with wired and wireless networks.



13

00:00:30.150 --> 00:00:32.700

As we begin this section, we're going to first take a look



14

00:00:32.700 --> 00:00:34.800

at different wired connectivity issues



15

00:00:34.800 --> 00:00:37.830

like electromagnetic interference, distance limitations,



16

00:00:37.830 --> 00:00:39.240

and things like that.



17

00:00:39.240 --> 00:00:41.580

Then we'll move into some different network performance



18

00:00:41.580 --> 00:00:44.640

issues such as slow network speeds, high latency,



19

00:00:44.640 --> 00:00:46.020

and port flapping.



20

00:00:46.020 --> 00:00:48.840

Next we'll move into our discussion of wireless connectivity



21

00:00:48.840 --> 00:00:51.690

issues such as intermittent wireless connectivity,



22

00:00:51.690 --> 00:00:54.930

signal interference, and slower than expected speeds.



23

00:00:54.930 --> 00:00:57.360

After that, we're going to cover some issues associated



24

00:00:57.360 --> 00:01:00.840

with voice over internet protocol services known as VoIP.



25

00:01:00.840 --> 00:01:03.450

This includes poor voice quality, high latency,



26

00:01:03.450 --> 00:01:05.940

and jitters inside of your communications.



27

00:01:05.940 --> 00:01:08.640

Finally, we'll cover limited connectivity issues



28

00:01:08.640 --> 00:01:10.710

and their potential causes so that you can solve



29

00:01:10.710 --> 00:01:13.110

these issues and get your end users connected back



30

00:01:13.110 --> 00:01:14.880

onto the network once more.



31

00:01:14.880 --> 00:01:16.860

Now, as you're going to learn in this section of the course,



32

00:01:16.860 --> 00:01:18.960

there are lots of different networking issues



33

00:01:18.960 --> 00:01:21.660

that you're going to encounter as a technician in the field.



34

00:01:21.660 --> 00:01:23.700

Our goal for you in this section of the course



35

00:01:23.700 --> 00:01:26.040

is to help you become that first level of support



36

00:01:26.040 --> 00:01:27.750

for some basic networking issues



37

00:01:27.750 --> 00:01:29.790

that your end users are going to experience.



38

00:01:29.790 --> 00:01:32.460

My goal is not to turn you into a full network technician



39

00:01:32.460 --> 00:01:34.890

or network administrator because that is reserved



40

00:01:34.890 --> 00:01:37.200

for the network plus level of certification.



41

00:01:37.200 --> 00:01:40.200

Instead, you're going to be the first line of defense.



42

00:01:40.200 --> 00:01:42.690

So let's get started with our coverage of how to



43

00:01:42.690 --> 00:01:45.590

troubleshoot network issues in this section of the course.
