hi i got linksys WRT54G im trying to block someone from my network i add his MAC address into wireless MAC filter yet it still show that hes still using my wireless everytime i check the DHCP client table. i even use the router access restrictions but still not working.
Yes if you change the network name and password all previously connected devices will be unable to connect, you will have re-connect all your devices, but it is the only sure way to cut off anyone you do not want on your network.
i should say this earlier but the one i trying to block out is within the house too. he dont do anything/work/ what so ever so im try to block him from using the internet but the Roku allow u to show password so he might of able to keep connection from viewing the password from there i did try MAC address filter both allow and deny but it keep showing up on Wireless Network Watcher(allow you to see whos using your wireless) i tried to test it on the PS3 and it does work but when blocking his wireless access it alway show up no matter what. so i dont know if it blocking it or not.
