The C1100z says dual stream and the C3000z says dual band, whats the difference?

The C1100z offers 802.11n wifi, which uses only the 2.4 Ghz band

for sending / receiving data. It supports two streams of 150 Mbps

for a (theoretical) data rate of up to 300 Mbps.

The C3000z offers 802.11ac, which has both the slower 2.4 Ghz band

for compatibility with older devices, as well as the faster 5.0 Ghz band

for sending / receiving data to newer 802.11ac devices.

If you have other 802.11ac devices on your network,

you'll get much better performance on those devices

if you utilize the C3000z, as it can reach a (theoretical)

maximum speed of 1.7 Gbps.

That's over 5 times the speed that the C1100z offers.

However, that speed increase only applies to devices

that have 802.11ac capabilities.

Check your manufacturer's website to verify.
