Can using network switch improve internet performance?

[NDDU Julius BSIT]

I recently bought a TPLink Network Switch today and I was wondering if it would give independent speeds for each device that is connected to the switch. It has 8x200 mbps RJ45 Ports in which one is connected to the modem. Currently there are 2 devices connected 1 is directly to the switch and the other is a wifi router (No LAN ports only pure wireless)

So you want to split the speed between the two devices? Unfortunately I don't know of a TP Link switch which can do that (but then again you might have a good model). If it has such a support, then you can split the network speed between the two devices, if not, best thing to do (what I have currently done in my setup is) set the router to maximum 60-70% of your internet speed so that the second device, connected to the switch has at least 30-40% of the connection speed available at any point. I do that to prevent lagging when someone is using the router and downloading.

I was wondering I have 3 mbps (Philippines ISP are stupid and crazy expensive) if that speed is consistent for all devices. 3 mbps from the modem, 3 mbps also on the two devices

There is no magic way to get more bandwidth from your ISP other than to pay them more money.

You have 3mbps total to share between the devices. To some small extent you can control which device gets how much bandwidth but that is a QoS function in your router not your switch. It also does not create more bandwidth it just decides who can use it. Even if you had a very advanced router that has very advanced QoS it does not work well on a small internet connection.

The only way a switch will increase you bandwidth is inside your house. You could for example hook up something like a security camera. The traffic between the security camera and some kind of DVR server would use the 100m ports on your switch to transfer data. They would not affect other machines on your connection or affect your internet connection. A switch really is just a very high speed connection device. Even very advanced ones are not commonly used to limit traffic, their function is to pass traffic as fast as possible. Other devices like routers or firewalls are used to limit traffic....but again it does not work well on a very small internet connection.
