Test 1: Single notebook (802.11n 2.4GHz Auto mode, 15 feet)
In our first 802.11n test, we ran the ThinkPad individually on Auto mode (802.11n Only), where the router selected the best channel and an appropriate channel width. Based on the results, the notebook scored 28.48Mbps, a far cry from the lower triple digit performance in our 802.11ac results.
Test 2: Single notebook (802.11n 2.4GHz 20MHz Only, 15 feet)
In our second 802.11n test, we ran the ThinkPad individually in 20MHz channel mode, which yields a maximum theoretical single stream bandwidth of 72.2Mbps. Based on the results, the notebook scored 27.21Mbps.
802.11ac/n Combination Results
For our final test, we connected the the Spectre x360 and iPhone 6 to the 802.11ac 5GHz network and ran the ThinkPad T440s on the 802.11n 2.4GHz network. The goal was to measure the router’s acclaimed 3200Mbps theoretical peak performance, though we did not have enough wireless devices available to test three in MU-MIMO on 5GHz (867Mbps each) and four on 2.4GHz (600Mbps).
Based on the results, the Spectre x360 scores 50.58Mbps, the ThinkPad T440s scores 36.29Mbps, and the iPhone 6 scores 13.39Mbps, for a combined total of 100.26Mbps.
