Today's video is
all about Wi-Fi. I will be demonstrating on my Samsung Galaxy Note 2.
Okay so let's get started. So if you go to your settings
straight away you'll see "Wireless and Networks"
and Wi-Fi. Now simply put, Wi-Fi is a way of getting internet
on your mobile device without connecting any wires.
Now you will need to have pre-installed Broadband in your home with any of your
countries Internet Service Providers.
with a Wireless Router. Now you should also have your wireless network
name and password close at hand, for this step.
now this here is the switch to turn your Wi-Fi on and off.
so if you just press it
and turn your Wi-Fi on, click on Wi-Fi, and we can get started.
Now because we turned our Wi-Fi on,
your phone will automatically scan for nearby Wi-Fi networks and display them in a list
here.
When you see your Wi-Fi network, click on it like so,
and this is the display box that you'll see.
Now, it will ask you for your password, so just type it in.
You also have the option here to check this box, called "show password"
and it will show you exactly what you are typing,and that way you can make sure that you're not making
any mistakes. So if you just finish typing in your password.
and click on Connect
It will authenticate your password,
and now your phone has Wi-Fi. Now if we go back onto this screen, you'll see another box here,
Labeled "show advanced options"
So if you just check that box, this what you'll see.
Now the first heading that you can see is "Proxy Settings"
A proxy is basically like
the middleman between your web browser and another computer
called a Server. Now a simple way of explaining how proxy servers work,
is to think of one person opening up a web page
and another person wanting to access that same page,
now instead of retrieving the data from the main server , the proxy has already stored
a copy of the page, when the first person opened it,
and sent it to the second person without burdening the Main Server,
which in turn speeds up Internet Surfing.
Now in order to use this option,
you will need to have a Proxy Server set up, and know the Proxy Host name and
Port Number. So if you want to set your Proxy settings, click on
"Manual" here, and this is what you'll see.
So if you just type in your Proxy Host Name,
the Proxy Port Number here, and here, for "Bypass Proxy For"
you can enter the web address for the page, minus the
WWW. So for,
www.google.com, you type
only the domain name, which is google.com
Know when you go onto these pages, the Proxy Server will not be used
for them, and it will access them straight from the Main Server.
Now click on "Connect" once you've done that,
and it will show up once you've typed in valid details in each of these three
boxes here, and then like I said
click on "connect" and you'll be set up. So If you go back onto this screen,
you'll see the other heading under "advanced options" which is IP settings,
right there,
IP stands for Internet Protocol, and you may have heard of an
IP address, which is basically like a postal address for your phone
on the Internet and consists of a series of numbers.
Now Internet Protocol is...well simply put, it's basically a set of rules,
for sending information between computers on the Internet,
that sets how one IP address communicates with another.
Now as you can see, there are again here, two options:
DHCP and Static.
So if we stick with DHCP for now.
Now DHCP stands for Dynamic Host Configuration Protocol,
and is controlled by a DHCP server, as you'd expect.
So having this option enabled, simply means you're letting a DHCP
server, assign your phones IP address automatically.
Now generally, dynamic IP assigns
a different IP address each time you log on to your phone.
But this does depend on your Internet Service Provider
because some Internet Service Providers only change the IP address
when they deem it necessary. Now the biggest advantage of dynamic IP
addressing
is that there is less of a security risk,
as you're assigned a new IP address each time you log on.
And that's all you really need to know about it. So now let's change the option
to "Static"
ok, and this is what you'll see
come up...like so.
Now on a Static IP address, you basically have
one constant IP address. Static IP addresses
are best used for;
Voice over Internet Protocol, which is basically a technology for making telephone calls
over the Internet. It's also best used for Virtual Private Networks, which are
private networks that use public networks to connect remote sites
and users together. And it's also best used for
playing online games, and game hosting.
Now dynamic IP addressing is less reliable for these uses, because
it could cause the service to disconnect.
But the downside to using Static IP addresses,
is they can become a security risk, because the address is always
always the same. So from here, you can change the IP address
from here, you can change the Gateway
the network prefix length, and you can also change the domain name systems from here
from here, simply by clicking on them, and typing it in.
Once you've done that, if you just click on "Connect", which will show up, once you put in valid
values, in each of these boxes,
then click on "connect"
and you'll be set up.
Okay, so finally back this screen, on show advanced options, you can see
your signal strength from here, and you can also see
what security protocols are in place to secure your wireless
mobile networks, from here. Now you will tend to see only three
types of security here. One is WEP,
which stands for Wired Equivalent Privacy,
which is a security protocol, for Wireless Local Area Networks,
and it's designed to provide the same level of security,as
that of a Wired Local Area Network, which
in turn makes it more secure, than a Wireless
Local Area Network.However, it's not the most secure protocol
available. Now the second option, is the one you see here, which is WPA
WPA2 PSK
Now WPA, is short for Wi-Fi Protected
Access, and it was designed to improve on the security of WEP,
and it has improved data encryption and user
authentication via the PSK. Now the
PSK, is short for Pre-Shared Key, and it's the pass phrase you
use to access the Wi-Fi. Now the third option,
is 802.1x EAP, and
it is said to be the most secure. Now EAP,
stands for Extensible Authentication Protocol,
and it provides a generalized framework for several different
authentication methods.Now there are three main processes involved here.
One, is the User, who wants to be authenticated.
Two, is the actual Server, doing the authentication,
and three is the device in between, such as
a wireless access point, which is basically the authenticator.
That's all you really need to know here, so let's go by onto the main
Wi-Fiscreen. So you can also add
Wi-Fi networks from here, just by clicking on "add WiFi network"
and it asks you for your network SSID.
SSID stands for Service Set IDentifier, which is basically just the
network name,
and then you can choose the security type, and
again just type in your password. You again have the option to click on "show password"
to show
the password as your typing it in. Once you've done that,
if you click on save, then
your new network that you've just added, will show up in this list here.
Now to re-scan for available Wi-Fi Networks, just click on
scan here, and you'll see a loading symbol,
and it will say scanning. However, I don't really see the point in that,
because very few seconds, it will show a scanning symbol,
as you'll see...there we are, and that was just after few seconds.
It does tend to do it automatically, but, they give you the option there, anyway.
Now that's the end of Episode 1, I hope you've enjoyed it. If you have any
questions or would like me
to review an app, or explain any features
or settings on your mobile device, please leave me a comment and I'll do my best
to get a video out.
Now I will be making more episodes, so please subscribe to my channel for my up-and-coming videos.
Thank you for watching. Android Top Tips
