Just hold down the reset button in the back of your router and start the process all over again. Just to be safe hold down the reset button for 30 seconds. Some will say a few seconds, but some say at most 30 seconds.
Do the reinstall setup again and dont name it the same.
ok i bought a NETGEAR wireless router. but i already got a wireless NETGEAR signal from my neighbor. i went to NETGEAR install wizard or something n it said change name ssid. my stupid self changed my netgear ssid to the same netgear ssid as my neighbors now i cant even connect to my neighbors anymore. when i scan my ps3 it still picks up as (no security) and 45% signal BUT NO SSID. PLEASE TELL ME HOW I COULD GET IT BACK I KNOW ITS NOT BLOCKED??????
