Basic mode status
The online simulator doesn't reflect the latest firmware, however, and there are some changes. The screenshot below shows the Advanced > System Tools > System Parameters > Wireless Advanced screen for the 2.4 GHz radio. You'll find the same screen for the 5 GHz radio, minus the USB 3.0 Interference Reduction checkbox. The Multi-User MIMO checkbox shouldn't be shown in the 2.4 GHz screen. TP-LINK confirms it's a bug and will have no effect on router performance.
The Airtime Fairness checkbox is nice to see, although I didn't test it. If you have lots of older, slower devices along with 11ac devices, you might want to enable this and see if it helps speed up your faster devices.
Neither universal or WDS-based wireless bridging is supported.

The summary graphic below from the Router Charts shows AC2600 and AC3100 / 3150 class routers we've tested with our standard procedure with USB 3.0 connections and NTFS drive format. The Linksys EA8500 remains the storage performance champ among all 4x4 routers we've tested. The Archer C3150 sits in the middle of the pack for both charts.
Storage Performance Comparison - USB 3.0 / NTFS
The Archer C3150 was loaded with 0.9.1 0.1 v005f.0 Build 160707 Rel.64418n firmware and tested with our V4 router test process. You can download an Excel test summary that contains all functional and performance test results.
Table 2 summarizes the performance test results. Both TCP/IP and UDP unidirectional performance for all products are now typically near the limit of the CDRouter testbed. This QA Cafe article further explains CDRouter's theoretical maximum application level throughput. The values include protocol overhead, which is why they're lower than 1000 Mbps
|Test Description||TP-LINK Archer C3150|
|WAN - LAN TCP (Mbps)||941|
|LAN - WAN TCP (Mbps)||941|
|Total Simultaneous TCP (Mbps)||1628|
|WAN - LAN UDP (Mbps)||382|
|LAN - WAN UDP (Mbps)||313|
|Total Simultaneous UDP (Mbps)||895|
Table 2: Routing performance comparison
Total Simultaneous TCP/IP throughput is proving to be a better performance differentiator. The highest performer so far for this test has been D-Link's DIR-879 AC1900 EXO router at 1850 Mbps. Results for other products are shown in the bar chart below so you can get an idea of how the Archer C3150 does by comparison.
Total Simultaneous TCP/IP throughput comparison
Most products fail the new maximum UDP connection test and pass the TCP connection test. But the C3150 failed both, establishing only 86 out of 3000 TCP/IP connections. For UDP, it was able to establish all 3000 connections, but couldn't keep them all open long enough (3 minutes) for the confirmation pass in the UDP test.
The Functional Score of 89.8% equates to 25 failed functional tests. In all, this is a decent score. The two largest groupings of failed tests were for UPnP and DNS functions related to the DHCP server.
As usual, some of the failed tests, such as HTTPs, fail because the router doesn't support HTTPs administration. The CDRouter triggered port test, which I've set up to require a single port and port range to be opened, also failed because the router doesn't allow the mix of ports in a single rule. Most routers fail this test because of similar restrictions on triggered port setup.
