Is there any difference between a large router and a small router

A router is a device that connects various LANs and WANs on the Internet, and it will automatically select and set routes according to the situation of the channel, and send signals in the order of the best path. A router is the hub of the Internet"Traffic police"。At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet.

The differences between the two routers are:

1. Generally, the so-called large router is a professional router for enterprises, which is mainly used in large networks such as backbone networks, enterprise networks, and campus networks, and is suitable for large-capacity, high-bandwidth, and multi-user situations. The so-called small router generally refers to the one used by home users or small and micro enterprises, and is suitable for users in the range of a few to a dozen people.

2. In order to process a large amount of data, professional routers generally have much higher software and hardware configurations than home routers.

3. There is a big difference. Professional routers are generally in the thousands to tens of thousands of dollars. And home routers are generally tens to hundreds of yuan.

There is a difference in the OSI reference model: the router used for large-scale projects is at the network layer, which can control the packets to the network layer, and each port and each data can be programmed to control. The router used in the home only belongs to the data link layer, which is similar to the switch, and the routing is based on software, and the broadcast domain cannot be divided at all.

And then there is **, it costs tens of thousands to buy a module for engineering routers. And the family only needs about 100 yuan.

The difference is big, and the small route is just a little bit of configuration.

The configuration of large routes is complex, but it is efficient!

If your small router has a fiber optic module, the key module is thousands of yuan!

There is no difference, it is the difference in the number of sockets. Internet cafes generally have 24 interfaces.

Yes, one is modular, the household ones are non-modular, the performance is far from the same, but at the same time the price is also far from the same.

Modular routers are generally enterprise-level routers, and home routers are called SOHO routers.

The small router --- use it to dial up the Internet for ADSL, and other computers use it to share the Internet. Its IP is:

Wireless router - and a TP-Link portable wireless network card--- this set of things can also be used for ADSL dial-up Internet access, and other computers can share Internet access through it. Its IP is:

What you want to achieve:

Wired desktop computers can share Internet access through A; The wireless laptop computer connects to B through its own wireless network card to achieve wireless Internet sharing. In order to achieve this function, I connected the WAN socket of B to the LAN socket of A.

Now, desktop computers can share the Internet through A. But if you use a wireless network card, you can't access the Internet.

Then, I did a little ping. Discover:

1。On a desktop computer with Internet access, ping the small route can be passed through the front picker A. But ping wireless router b, it doesn't work. Ping a laptop connected to a wireless router is also not working.

2。On a wireless laptop that does not have Internet access, ping the wireless router B can be passed. Ping small router a, you can also pass this rock. Ping the desktop computer on the small router A, which is also passable.

Question: 1, I don't understand, why can you use a laptop to ping a desktop computer, but you can't use a desktop computer to ping a portable or small router B?

2。Can I actually achieve the function I want?

3。If so, how should the hardware be connected and the software set up? Silver Knowledge.
