So this was really weird...it came with a 54g wireless card in it...I bought an intel wireless n card for it...I installed it and used it for a few weeks...well last night I restarted it and all of a suddon, I get the 104-unsupported network device....well before I got to reading I upgrade the bios to its latest version which is vesion .20 or something...well I did some research and found this website, and how to do it...well I download the stuff I need, and the hacked bios for my laptop listed here is .16...so now the question is how do I downgrade my bios?
