Internet connection

[Space1]

Hello,

Have two networks in the computer.
Can't connect one network to the internet even if I turn off the other that is connected to the internet. You have to have two network cards in your computer to connect both at the same time to the internet?

hi

sorry, but what exactly do you want to do?
if you have a wired card, and a wifi card, you can use the internet, being connected to wifi, or lan!
there is no particular interest, if you try to connect to both at the same time..

Hi,

Will explain more what I intend to connect to the computer.

2 pcs of ESP8266 5V WiFi Relay Module Smart Home Remote Control Switch Phone APP should be connected.

Can see the module in the computer but does not know how to connect it to the internet.
Network 1 is connected to the internet I try to connect network 2 so this does not work. I wish that both networks 1 and 2 are connected simultaneously to the internet.
.
Grateful for suggestions.

I do not understand at all what it is for exactly, I see here, that it is mentioned mobile phone ..
I won't waste your time, even if I find the website for this product, I'm afraid I can't help you more!
I don't understand how it should be connected, and what exactly it is for

@BeemerBiker  maybe ?

As @Prométhée mentioned, it is not clear what you want to do.

There are advantages to having two ethernet ports as explained here

If you want both ports on the internet you will need two routers and software to combine (load balancing) as explained briefly explained  here

I have a home surveillance system on one port and internet on the other.  That way, any backdoor or trojan in the foreign made cameras cannot "phone home" as they have no internet access.  Basically two ports are used to separate devices from one another.  Combining devices will require 3rd party tools  Please read up on link aggregation

The two devices you listed are designed to plug into an Arduino system.  

If you put both Wi-Fi devices on a single Arduiino typically one would connect to the internert and the other could be used to connect to Wi-Fi cameras or various Wi-Fi appliances.  

Hope this helps
