Wireless Performance - Competitive
For a competitive comparison, I generated a Wireless Comparison Table for the 2130n and two other single band N routers with Gigabit ports, the ASUS RT-N16 and EnGenius ESR9850. Figure 14 shows that the 2130N was a clear winner on downlink. But the three products were more evenly matched running uplink, although the EnGenius won the comparison with three bests vs. two for the other two routers.

Given the limitations and other issues with the 2130n's wireless feature set, I'd say its wireless portion is the weakest part of the product. And I certainly would not recommend buying the 2130n for its wireless performance alone!
The 2130n is a damned fast wired router with extensive QoS features. But its high price ($243), limited availability, modest IPsec tunnel throughput, missing wireless controls and buggy USB drive file sharing make for a poor overall value.
