I’ve said this before, but many marinas and yards now have 5 Ghz WiFi. 2.4 Ghz is the more common one used by users and can be more congested and slow down at some locations. 5 Ghz has more radio frequency space and is less used and can give you a speed boost.
Dual Band Marine Wifi – Now Available in the same form factor as Link-2 and Link-5 but both bands in one system.
Complete Package with cable and antenna. Power-over-Ethernet for easier cable routing. No need to pull a fat coax cable.
B/G/N on 2.4 Ghz and A/N on 5 Ghz.
500 mW Power Output …
