If you have an internet connection then using it as ethernet is going to be quite simple. All you would really have to do is take the cable that is connected to the modem, the cable that provides the internet to this device which it then proliferates through some kind of wireless broadband signal. This can be great for a lot of reasons but the fact of the matter is that usually a single internet connection is used by all kinds of people at the same time, and making sure that everyone has access to the internet is actually quite important all in all.
If you still want to convert your wifi to ethernet and want to make sure that everyone else that uses the connection can use it without any interruptions there is a solution for this as well, and this solution is essentially associated with connecting some kind of an ethernet cable that is connected to your router. This means that half of the bandwidth would go to your device through the cable and the router will provide the rest of the bandwidth to anyone that might be using the device through a wireless connection.
This means that you won’t get the maximum speed possible but you would get enough to get by and what’s more is that you would potentially be able to provide everyone else with a decent connection as well. This way everyone wins more or less and visiting zappedia.com/wifi-to-ethernet-bridge/ can help you learn more about the various benefits that are associated with using the internet in this manner and ensuring that no matter what happens you are able to get things done without having to worry about anything else in this regard.
