I am thinking about AirPort Time Capsule 3TB (802.11ac) and I am wondering if my iMac will benefit from a better and more stable WiFi connection/speed. At the moment, I have a Linksys EA6900 dual band AC router, and I am not impressed with range - the iMac is about 3 meters away, but the connection txRate drops often on the 5GHz band. I must say that 2.4GHz band is pretty busy as all neighbors are using it, but the 5GHz is only my router. Apart from gaining a 3TB Time Capsule, will I see an improvement in WiFi? Is it worth purchasing? Money is not the concern here, I can find another use for the Linksys router, if I knew the AirPort will work better for the iMac.
