There are several issues with marine
WiFi that you should consider.
The WiFi spectrum is made up of 12? Overlapping frequency bands. Think... Your at a party.. You are having a conversation.. But you can hear the other people as well - the noisier they are the harder it is to hear the person you want to.
For boat use your going to want a high gain external antenna
. This takes the electrical
signals and send them across the air. The higher the gain of the antenna the louder you will be heard, and the more you can hear.
This is your megaphone.. The bigger the gain the more you can hear. But higher gain means physically bigger too.
More radio waves have to hit it.. So it has to be bigger.
For most of us we want an omnidirectional antenna. ... So we don't have to turn it to point in the right direction.
I have 2 .. A 9dB and a 15dB... The later gets signals from my marina at 12nm heeled over. The mount was gimbaled with the radar
The later you leave the network signals in digital form the less they will be degraded. So you want the Wi-Fi transmitter at the antennae. The network people do this a lot so they are used to sending power up the cable. However check your power inserter. I blew 2 before I worked out that the bat charger
and it went playing nice.
Inside the boat you have to decide what you are using the network for. And if you need a firewall between u and the outside world. Thankfully most cheap
products now include a firewall. However try and have your internal network on a different band than the external... Otherwise some one is trying to shout 2 conversations next to each other.
My internal net is on 5Ghz.. As not all devices support 5Ghz you need to be careful about buying
Lastly protect your net with a password. Just follow the instructions. Why.. Well you will likely gather loads of personal information on your net.. So keep it safe.
Hope this helps!
