Airport Extreme with older Airports...

[Chuchichan]

Hello...Just wondering if I purchase a new mode Airport Extreme and connect my older Airport Expresses (G and N models) to the wifi network, if that will slow things down?

Would it be more advisable to purchase new airport expresses as well?

Thanks...

Yes, because the AC Wifi Standard has more bandwidth compared to the older standards.

Would it be more advisable to purchase new airport expresses as well?

No, because Apple hasn't refreshed the Airport Express, yet. Its still 802.11n.
So there is no point in throwing away your old Airports with g+n wifi and buying new n-wifi airports.

In the end it all depends on your setup/planned setup.

Edit: if you use your network only for internet there is probably no point in upgrading to ac-wifi.
Except if you need a better connection (because the Airport Extreme has 6 Antennas, but i wouldn't recommend it just for AC, because there are other AC-Routers with better reach)

byte =/= bit

with DSL 50000 you can transfer 6,25 Megabyte per Second (DVD-Image @ 4,37 GiByte takes 12m 32s)
with DSL 100000 you can transfer 12,5 Megabyte per Second (DVD-Image @4,37 GiByte takes 6m 16s)

802.11ac can theoretically transfer 1,3 Gigabit per Second = 162,5 Megabyte per Second (DVD-Image @ 4,37 GiByte takes 29s)

So Lets see DSL 100000 @ 12,5 Megabyte per second vs ac-wireless 162,5 Megabyte per second. (7,69%)

Wireless AC is useful for your home network (streaming data, copying files wireless) or when your wifi reception is bad and you need better wifi (6 antennas iirc in the airport extreme ac + its 5Ghz so less interference) for your internet connection.

Hope this helps

Edit:
Better Example: Right now my Macbook (AC) Connection to my Router (N) is @130 MBit/s
My Q10 (N) right next to my Macbook is only connected @65Mbit/s.
This might not apply 100% to your situation, but the better wifi module (more antennas) helps with wifi reception.
