Thanks for sharing, I also think that the its somewhat limitation of 5ghz band. That's why will only consider the c3150 if going with router upgrade option since is 4 antenna for signal.
If you wish to have 5ghz full coverage for multiple floor.
I don't think even C3150 can do that. As C2300 is like slim down version for C3150 in hardware spec.
C2300 3 antenna and C3150 4 antenna, there isn't much device support 3 or 4 antenna in real life eg. phones etc.
C3150 might have better coverage than C2300, but i think that is limited improvement where you still can't get 5ghz coverage full house due to multiple floor.
*As you wish to have 500mbps internet where only 5ghz able to achieve
Therefore, mesh router option will be better to achieve 5ghz signal better coverage.
