Port Networks’s approach to maximized marine WiFi is to minimize coaxial loss by packing a high-powered radio and 5.5-dB antenna into a waterproof box for deployment on deck whenever you’re docked or moored. Both power and signal run through a no-loss 25-foot Ethernet cable. While the $349 MWB-200 will usually find the best available WiFi signal automatically, complete control software is accessible via any Web browser. In several areas tested, the MWB worked well when normal WiFi failed. Note that this unit does require 110-volt AC power, but that it can be used most anywhere (such as in a hotel when you’re not cruising). Port Networks; 410-637-3707, www.portnetworks.com
