I want to pose some scenarios and questions to get a better idea of the impact that utilizing multiple connections and interfaces on a single device will have on connection speed.
- Scenario 1: Three routers all with separate connections to the internet, and one computer with two gigabit ethernet LAN ports and a wireless card
- Question 1: Would there be a significant speed boost if the computer connected to all three routers at once using the three possible interfaces?
- Scenario 2: One internet-connected router with two ethernet LAN ports and wireless capability, and one computer with a wireless card and two ethernet LAN ports.
- Question 2: Would there be a significant speed boost if the computer connected to the router using all three possible interfaces at once?
- Scenario 3: One offline wireless router/switch, with four ethernet LAN ports and wireless capability, and two computers, each with two ethernet LAN ports and wireless cards.
- Question 3: If I connect the computers to the router/switch using all possible connections (four wired connections, two wireless connections), would there be a significant speed boost in transfers between the two computers, as opposed to if I only used one possible connection per computer?
EDIT: Rationale for asking the question. I'm shopping around for motherboards and one gaming one keeps popping up which is selling itself as having two ethernet ports for "double the speed". I was skeptical but figured it might be possible.
The other reason is that I live with someone who can control over whether or not I can access internet on the ADSL by disabling the wifi on the router. He does this regularly. So i was looking into solutions where I have a wired connection to a 4G router, while wirelessly connecting to the ADSL router simultaneously. I was wondering if this would provide a speed boost at all.
