Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Very few boards have built in wireless. Only a few ASUS ones. And the boards usually have a hefty price premium. As their more of an OCers board.
However I once tried finding specs on the built in wireless to see what encryption standards and such it supported and was unable to find anything at all about it. When a manufacturer doesn't publish any info on their product it worries me...
I'd say to just buy a pci wireless card and use it, if your not going to use SLI or OC much no point in buying an overly expensive board.
