Your information is very helpful handyman, i even call my more tech-savvy friend, and he suggested me to install desktop network pci card and after he tweaked a little bit with my usb modem, my wireless is now working!!! Hooray!!!
Not for my laptop though, it works but i don't think my old laptop can handle such pressure since it's getting to 100% cpu usage all the time. At least i can use wireless for gaming eh?
Also, should i put password on wap/wep? WAP password is too long and i don't think my gaming device supported it, so could i just put password on wep? There's an option where you can just type what I want and it will generated key for me. Should i choose that? I don't want to remember like 46 digits of passwords.
Anyway, i'm very chuffed right now. Sorry guys for my extreme noobiness.
