What is satellite internet access and how does it work?
Why is satellite internet access slower than a normal connection on land?
A number of things may interfere with this, like storms and large objects that can block the signal, such as steep mountains close to the ship or tall buildings in ports. This interference can result in slow response times or even the system becoming unresponsive.
When is the best/worst time to use satellite internet access?
It is therefore best to avoid these periods if possible.
