Routing Performance

Routing performance for the 880L using our standard test method is summarized in Table 5. At least here, the 880L does pretty well. Sure, its unidirectional up and downlink throughput tends to make you scroll down a bit to find it in the Router Charts. But you really can't complain much about the throughput, which is more than enough for most internet connections.

Test Description DIR-880L
WAN - LAN Throughput - (Mbps) 766
LAN - WAN Throughput - (Mbps) 810
Total Simultaneous Throughput - (Mbps) 1354
Maximum Simultaneous Connections 37,689
Firmware Version 1.0.1
Table 5: Routing throughput

The IxChariot composite plot for the unidirectional tests shows steady throughput, with periodic spikes into the 900 Mbps range.

The simultaneous up and downlink plot below shows a preference for uplink traffic when both directions are running full blast. The jump up before 20 seconds is an IxChariot quirk. But the ramp up in WAN > LAN throughput after 30 seconds or so was reproduced in multiple runs. Still, the 880L should provide plenty of routing throughput.

Wireless Performance

The 880L is Wi-Fi Certified. It defaults to Auto channel on both bands and auto 20/40 MHz B/W mode on 2.4 GHz and Auto 20/40/80 MHz mode on 5 GHz upon power-up. The router comes with different 2.4 and 5 GHz SSIDs set, so you'll be able to connect to your desired band without having to change router settings. The wizard that launches upon first login walks you through changing these settings as well as encryption.

The quick WPS pushbutton test with a Win 7 client ran without a problem, connecting with a WPA/AES secured connection. I skipped 40 MHz Coexistence and Fat channel intolerant tests and will probably stop mentioning this going forward.

Wireless throughput testing used our new Version 8 wireless test process with 1.0.1 version firmware loaded. The router was first reset to factory defaults, then Channel 6 and 20 MHz B/W mode was set for 2.4 GHz and Channel 153 and 80 MHz B/W mode was set for 5 GHz. The router was positioned in the test chamber with the antenna row centered on the turntable side-to-side (of chamber) and middle antenna centered on the turntable front-to-back. The 0° position had the front side of the router facing the chamber antennas.

The Benchmark Summary below shows the average of throughput measurements made in all test locations. The results rank the 880L in a tie with the ASUS RT-AC68U in third place among AC1900 routers tested, below the NETGEAR R7000 Nighthawk in first and Linksys WRT1900AC in second.
