hello, We currently have 2 MacBooks running mountain lion and we would like for both of us (me and my brother) to get a new router and a usb HDD (around 1tb or so) for use with time machine, no manual backups, i want to be able to have it back me and him up automatically when we are on the wifi at our house. i am super tech savvy and am willing to try about anything, we sure as heck aint buying a $500 time capsule. also, i currently have another router acting as a repeater at the other end of the house, if that makes any difference. (its not that important as any newer router will be better signal strength wise than our old ones. if anyone knows how to do this, that would be great! and if you need any more info, I can give you any info at all thanks!!
