We all know that the Nintendo Switch and the Switch Lite are fantastic little pieces of hardware. However, there is a smattering of small complaints about these devices. One such gripe I have heard about more than a few times is that neither Switch offers any sort of built-in web browser. The good news is that you actually can use a web browser on your Switch, and you don't have to do anything as warranty breaking as hacking your gaming system. If you want to surf the net on your Switch or Switch Lite, here's how to do it.

It's important to note that, by accessing the web browser on a Nintendo Switch or Nintendo Switch Lite in this un-official way, you risk having your personal information tracked and stolen, as this is not a secure method of web browsing. Please don't use it without considering the risks.

You now have access to a browser right on your Switch. Once you are done using the browser, all you have to do is go back and set your network DNS from Manual back to Automatic. If you want help with changing back to Automatic, follow the steps below.

Select the appropriate network name (SSID) from the list.
If you are unable to find your network's name, stand closer to the wireless router and press the Y Button to search again.
If the network name is grayed out, this indicates the wireless security type being used is not supported by the Nintendo Switch.
If you are still unable to find your network, this may indicate an issue with the wireless network environment.
If prompted, use the onscreen keyboard to enter the network's wireless password

Essentially, switches are the traffic cops of a simple local area network.
Techopedia explains Switch
A switch in an Ethernet-based LAN reads incoming TCP/IP data packets/frames containing destination information as they pass into one or more input ports. The destination information in the packets is used to determine which output ports will be used to send the data on to its intended destination.

Switches are similar to hubs, only smarter. A hub simply connects all the nodes on the network -- communication is essentially in a haphazard manner with any device trying to communicate at any time, resulting in many collisions. A switch, on the other hand, creates an electronic tunnel between source and destination ports for a split second that no other traffic can enter. This results in communication without collisions.

Switches are similar to routers as well, but a router has the additional ability to forward packets between different networks, whereas a switch is limited to node-to-node communication on the same network.

A network switch is a hardware device that channels incoming data from multiple input ports to a specific output port that will take it toward its intended destination. It is a small device that transfers data packets between multiple network devices such as computers, routers, servers or other switches.

In a local area network (LAN) using Ethernet, a network switch determines where to send each incoming message frame by looking at the physical device address (also known as the Media Access Control address or MAC address). Switches maintain tables that match each MAC address to the port which the MAC address is received.

A network switch operates on the network layer, called layer 2 of the OSI model.

Network device layers
Network devices can be separated by the layer they operate on, defined by the OSI model. The OSI model conceptualizes networks separating protocols by layers. Control is typically passed from one layer to the next. Some layers include:

Layer 1- or the physical layer or below, which can transfer data but cannot manage the traffic coming through it. An example would be Ethernet hubs or cables.
Layer 2- or the data link layer, which uses hardware addresses to receive and forward data. A network switch is an example of what type of device is on layer 2.
Layer 3- or the network layer, which performs similar functions to a router and also supports multiple kinds of physical networks on different ports. Examples include routers or layer 3 switches.
Other layers include layer 4 (the transport layer), layer 5 (the session layer), layer 6 (the presentation layer) and layer 7 (the application layer).
