I am pinging the default gateway for this particular SSID which is internal.
I ran a perf-test from the controller to the AP where both clients are connected to:
(aruba-wlc3) #show perf-test reports ap ap-name M7A-1OG-AP02
Perf-test: Success

I connected a PC running Ubuntu on a wired LAN port to the same VLAN as the wireless clients and set up an iPerf server on it.
Then I ran an iPerf test from the 802.11n Acer laptop and from the 802.11ac Lenovo laptop. Results in Green are from the Acer, results in Red are from the Lenovo:
