dayum how did you do that well is it a psn block or a ip block. coz if its just a psn 1 you can make another aco**** till you ps3 aco**** opens up again
you can make a new psn using a different wireless network then the current one or if ur not wireless then use wireless (such as a neighbors account which does not need a WEP key)
if there wifi says the company order the setup disk from that company. run the Create security key on the disk in yo cmp. on "really difficult" setting.
it will throw standardized key sets at you try about 5 diff. ones and you should be in.
then use ur neghbors wifi whenever.
it worked for me with linksys.
i'm not responsible if they somehow figure out ur on their network.
