WiFi Protection

How to secure my WiFi. Look at the picture, 5 out of 8 are intruders. Is there any simple software through which I just click and disable to access the WiFi.

Thanks.

why not log into your router and put a WPA key on your wireless

Well, I tried that but once I do some changes in there, my network connection is not going to work either.

Look at this screen and guide me here as well (what to do here).

(Some guys told me you need to connect the router with wire. you cannot do this using wireless, is this correct?)

many thanks for your time

Yep that's the right screen. I would connect to it with a cable. Everything looks fine on that screen. Just put in a passphrase (a long word with numbers and letters that no one would guess) and submit it. Your current machines will lose connectivity if they're already using wireless because you've put in a password. If you're connected by cable then you're ok. You'll need to re-connect to the wifi and put in a password if you're using wifi with your laptop or gaming system.

So, if I do this all, Do I need to enter that password every time I need to connect to Internet?

Kennyboy5IT Support AnalystCommented:
Anything that uses your WiFi will need the password entered in once. WiFi devices will remember the password after that.

my advice...

choose WPA
WPA Type:  WPA2
Encrrytion Type: AES

just write a "password" where it says PSK Passphrase

you don't need to enter that password every time you connect to Internet... Windows7/8 will only ask you for that password once, without specifying the settings I told you before..

in Windows XP you may have to manually set it up:

WPA2 is a better option.  It is a much stronger encryption.  If you have WiFi N clients, WPA2 is a must.

Just Curious!

What is WPA and WPA2?

What is TKIP and AES?

Is it better to hide SSID as well? (See my first attachment jpg file.) Some online resources say that. Not sure.

Regarding TKIP vs AES, this LINK have good information about that...

Regarding SID hiding, it is good form moving regular people from trying to connect to your AP, but someone with higher skills/knowledge if he wants he will get your SID.. So in terms of hacking, hiding sid doesn't protect you from someone hack into your AP while wpa/wpa2 with long passphrase does.

Hiding your SSID is useless.  It is a poor security measure that won't be an obstacle to a determined intruder.  WPA2 and long and complex phrase is the best protection measure you can take and I highly recommend it and your first WIFI line of defense.

WEP encryption is the weakest. WPA is stronger and WPA2 is the strongest using AES. I don't use WPA2 because my playstion3 won't accept WPA2. So if you have any gaming consoles that use WiFi you might want to stick to just WPA. If just computers using your WiFi then you can go with WPA2. Keep in mind some older WiFi cards with older drivers may not allow you to pick WPA2 as they may not support it.
As for hiding ssid, like posted above its not a major security feature. Your devices just won't see your WiFi being broadcast and you'll have to manually setup your WiFi connections.

Here are the solutions, in order, from best to worst:
1. Enable WPA2 encryption with AES
2. Enable WPA encryption
3. Enable WEP encryption (highly insecure easy to crack)
4. Enable MAC address filtering (insecure, easy to bypass)
5. Change and hide your SSID (most insecure extremely easy to bypass.)

@leoahmad,  WPA nad WPA2 are security protocols... in       layman's terms ... it defines how your "message" goes from point A to point B applying algorithms (encryption) to protect your message, in this case AES or TKIP.

Very nice and handy information for me as a database developer. I will go through all these on Sunday and then award the points after weekend.

Thanks very much for those lovely points to my knowledge base.

OK, What I did was:

I disconnect all my WiFi devices and then connect my laptop to the router with a wired LAN.
I opened the device main page and set the settings to WPA --> WPA2 and AES and the give a pass phrase.
then submit it

every thing seems to be alright.

BUT

now I am not able to connect any of my device with router using WiFi (not even my laptop) as none of my system could detect the router now.

What I am missing here.

Thanks

Are you hiding the SSID with that checkbox? If so then you can uncheck it and apply the settings.

no i did not do that

(see my attachment of router homepage in an earlier post)

I just click the WPA and WPA2 and AES and enter after adding a phrase I submit it.

But none of my computer can now detect the WiFi automatically (I was hoping it would connect automatically, but it did not) . Do I need to do something extra now.

If I reset the router and switch on the computer, it again connects the WiFi automatically, but after the above security measures I am not able to connect myself (Very High Security... Lols)

Does your laptop even see the router? If not just do a refresh on your laptop to view available wireless networks. If it still doesn't work then it's possible that the wifi in your devices don't support the WPA2 AES setting. You may want to drop it back to WPA2 TKIP or even WPA TKIP

I refresh it many times, even I restart my laptop. But it does not work.

Ok, I will check your other option and let you know.

Thanks.

zte ix380 is my wifi device anyways.

any updates?

if no... please post all the devices you want to connect... brand and model please

router too please

Muhammad Ahmad ImranDatabase DeveloperAuthor Commented:
router is zte ix380
my laptop hp 4520s
my home computer
my nokia n8 mobile phone
my bro's apple laptop
my bro's iphone

no one connect after applying any of the security settings. no device could find wireless network availability, but after disable security all devices can be connected so do the unwanted clients as well

?? a mystery for me ??
