my ps3 is wireless. i bought a cisco router and pluged it into my motorola modem. i did everything right cause it worked. but i took it over to my friends house and changed it to work there and he has WIFI. when i brought it back to my house it wouldn’t work. we tried bout 6hrs to figure this sucker out and got nothing, we called best buy, psn, even our cable company and they reset the cisco, but now it doesn’t work and we don’t know what to do. we cant seem to find the right password again. can anyone help us?
