Wireless local area networks (WLANs) have become quite popular in recent years, in both home and business networks. A wireless network is easy to set up and can quickly connect several computers without the need to run cables, which significantly reduces costs.

Wi-Fi network has a great concern due to the broadcast over the air, anyone who has a wireless transceiver can intercept the transmissions. You can secure wireless networks with several different steps, but the most important step is to implement a security protocol, such as Wi-Fi Protected Access II (WPA2).

The following sections describe the primary security protocols available for wireless networks.
1. WEP

At first when wifi was launched the whole community aligns started a security system which is now known as WEP (Wired equipment privacy) .
Around 17 years ago, this was a one of the most advanced security protocol. But, Now a day’s they are very easy to crack it therefore never use them.
Due to the widely published vulnerabilities of WEP, the IEEE deprecated the use of WEP in 2004.
2. WAP

Wi-Fi Protected access (WPA) was an interim replacement for WEP.
It provided a solution for WEP. But, this protocol is for the very short time, With this one more protocol added in to the family WPA2.
3. WPA

WPA2 is the permanent replacement for WPA. WPA2 uses a stronger cryptographic then WEP and WPA.
WPA2 works in a two different modes WPA2 and WPA2 PSK.
PSK means preshared key.

WPA2 is more secure than WPA. It is the full implementation of 802.11i standard for securing a wireless network.

WPA2 uses a very secure encryption algorithm AES(i.e. Advanced encryption standard) and provides a high level of security than WPA. WPA uses a TKIP(Temporal Key Integrity Protocol) encryption standard for encrypting the data.

AES(Advanced encryption standard) is uncrackable by even the advanced skills hackers, that’s is the reason for the security of WPA2.

Stronger encryption is the main reason behind the security of the WPA2.
WPA2 has designed in two modes for different types of network.
WPA2 PSK is intended for the use of small office and home network.
Each wireless device is authenticated with the same 256 bit key.
It is always recommended to select WPA2/PSK while setting the password.

We cannot say that, by selecting WPA2/PSK will save us from hacking issue. It is basically a most secure encryption types. So, don’t create a simple password like demo or test. It can be easily cracked by the brute force attack. Password must be the multiple combination of letters, symbols and numbers.
Conclusion:
If you are using a older versions router there might not be latest encryption types till time. You can try using MAC filtering. If your router does not support too. I request you to kindly change the router.
You can also provide the minimum security to Wi-Fi by disabling the SSID, Which lets you to hide the Wi-Fi network publically and add a level of security to your Wi-Fi.

Some security experts have reported cracking WPA2, though their techniques have not been freely available to the public or reviewed by peers.

Don't dissable the SSID transmiting!!!
1. It's easy to find hidden wifi networks
2. Hidden networks are a pain to deal with
3. Not all devices support hidden networks
4. Hiding the Network Leads to Connection Problems
Just use WPA2 and you'll be fine, just make a strong passprase and change it regulary.

This is acutally a great tutorial for people who don't know anything about setting up their WI-FI network. The thread could use some proper formatting but it's great information. Thank you for the share.

As @Bish0pQ mentioned, this Is a good guide for those who're starting off In protecting their Wi-Fi network.

Just adding to this, a lot of users completely overlook their Modem/Router's default login (admin:admin, admin1:admin1 etc), therefore leave It as Is. I strongly suggest changing It and also (where applicable), turn on the Router's firewall and configure all rules accordingly.

My router actually forced me to change these details manually when I first connected to it to set-up my internet, but this isn't the case with most, I believe.

Given I've gotten into other people's routers before using the default, this is a pretty big step for securing it.

That's a good security Implementation put In by the manufacturer.

However, not all Routers are defaulted as such. I think you're correct In that most Routers do not prompt to change the default login credentials.

Also another tip is to change your routers default password and username if possible. Your router could sumtimes be accessed if the manufacturers manual have the default password for the model online.

Just use WPA2 and you'll be fine, just make a strong passprase and change it regulary.

Actually, I don't think changing the password regularly for no reason is a good practice at all for wifi networks.
Changing your password regularly, especially since you probably have to share it with others will make you use weaker passwords, intentionally or not.
So just have 1 strong password, and only change it when neccesary., like when your roommate leaves or when you detect a device not your own on the network.
