We tested the X150N against other Wireless-N routers, and though this is an unfair battle--as most of others were dual-stream routers--it performed well in our short range test.
In this test, the router was placed just 15 feet away from the client and was set up to offer the best possible throughput speed. It scored 37.3Mbps; at this speed, the X150N can finish transmitting 500MB of data in about 107 seconds.
In the 100-foot range test, however, the X150N scored much lower at 17.4Mbps. In the mixed mode test, where the router was set to work with multiple close range clients of different wireless standards, including N and legacy G, its score was close to that of the close range test at 32.2Mbps.
Overall, we were happy with the router's close range performance and wish its range performance were better. The router's range was also rather long for a single-stream router, at about 220 feet.
Unfortunately, the router didn't pass our 48-hour stress test, during which time it was set to transmit a large amount of data back and forth between different clients. The router reset once during this time, which was not the worst we've seen but we expected the router not to reset at all.
