Need some advice from Apple networking gurus... I currently have a Linksys WRT54G (b/g). It works decent. I'm wondering if my network would benefit greatly from the upgrade to an AEBS. I have several Macs, iPhones, gaming systems and soon an iPad. I do stream some video over the network. I have cable internet (around 7mbps). I know the numbers say I'd only get better speeds between devices. Is the AEBS more efficient that especially with many devices, my internet response would be snappier? Would the dual-band help with the mix of b/g/n devices? Or is wireless N pointless until I have crazy ISP speeds? How about range vs the Linksys? Thanks!
