Size matters, and if you want a minimalist range extender, you’ll like that the $66 Belkin F9K1122 is small. However, like its larger Belkin cousin, the F9K1122 had trouble connecting in our Manhattan office.
While the extender has one LAN port, many of its competitors offer four, and the F9K1122 lacks USB or audio jacks. You can swivel the antennas, but they are permanently attached, so forget about removing them to use more sensitive ones.
Unfortunately, the F9K1122 couldn’t reliably connect with devices over the 2.4-GHz band in our Manhattan office, which has lots of interference from other networks. It worked well in a less-crowded environment and delivered top-notch 5-GHz performance. It pushed a total of 208.5 Mbps and had a range of 140 feet, making it a worthwhile extender for those who want to think small.
