1. Open your web browser and type in your routers IP Address which can usually be found on the underside of the router. the default username and password will also be there use this to login to the router.
2. Look for Wireless settings or similar then the wireless encryption section. if the encryption setting is WEP then you must change this immediately to WPA2, as WEP encryption has been cracked and will take less than 5mins to get the password to even a below average hacker. (there are plenty of guides on YouTube on how to do this.)
3. under were you chose WPA2 there will be a box called WPA2 Passphrase. this is where you will enter your new wireless key. now for the best password use numbers and upper/lowercase letters. something like
LiverpooL1892 or StDomingo1878
these would both be secure due to the mix of upper and lower case letters and numbers, also they are not dictionary words.
4. Two different types of attack are "dictionary" and "brute-force"
*(1) Dictionary attack:- hacker used a text file containing dictionary words from multiple sources and also common used passwords to compare to the wifi key.
*(2)Brute-force: hacker runs a program to try all possible combinations of numbers and letters to crack the wi-fi key.
so if you use a non dictionary word for your passphrase like my suggestions then the first attack is pretty much useless. as for brute-force attack. this is a simple case of maths.
say you use a random series of letters for your passphrase(like sky or BT do) that is 8 characters long like RHMJAYET, notice they are all uppercase and hackers know this, then the maximum amount of 8digit keys they will have to try is
26 to the power of 8, (26 possible letters, 8 characters long)
26^8= 208 827 064 576 possible combinations
now the addition of lower case letters makes it 52^8=5.34597285 × 1013
add 0-9 and then its 62^8=2.18340106 × 1014 [continues]
