Right ive tryed writing this out 5 times now (things aint going good 4 me today) so instead of a fucking essay just wana know how do i get ppl off my router because i goto DCHT clients or whats it called.. & it brings a list of 8 ppl :S like george, lampard etc WTF the fook are they!!!

then i goto mac address filter & put there mac addy in to block it but i cant it says mac addy cant be blocked because its logged on my router!!!

i put a password on just before i even noticed all them ppl

ive forgot what its called but it said all my wireless & such users will need this password so that will help? & them ppl log off?
What can i do? i've unplugged the router now but obviously im the only one who can only use the internet now..
