The wan port of the router is broken. can I use the lan port? (how does the router act as a switch)

Hello everyone, Lin Fei to answer the above questions, the router wan port is broken can you use the lan port, how the router when the switch many people do not know, now let's take a look!

If we have two TP-LINK wireless routers, in order for these two wireless routers to work together, we must turn one router into a switch.

It takes three steps to change a router to a switch.

Step 1: turn off the router's DHCP service ("DHCP server"-"DHCP service"), as shown in the following figure.

Step 2: change the ip address of the router ("Network parameters"-"LAN Port Settings"). Note that the ip address cannot be the same as the IP address of the main router, otherwise it will be offline.

Step 3: all network cables are plugged into the LAN port of the router, and no network cable is plugged into the WAN port.

Through the above three steps, this router only has the function of the switch.

How do I connect to a wireless router from the lan port of a wired router?

Today, I came across a case where a customer had to connect a neighbor's wired router to his own wireless router. In this case, the wired router is actually the gateway to the Internet. Simply connect the WAN port of the wireless router to this gateway.

The steps are as follows:

Step 1: connect the LAN port of the wired router to the WAN port of the wireless router.

Step 2: set the Wang port of the wireless router to "static IP".

Note:

1. Try to set a larger IP address to prevent it from duplicating the IP addresses of other computers in the intranet. (also modify the IP address of the router)

two。 The subnet mask is 255.255.255.0

3. The gateway has the ip address of the line router, which defaults to 192.168.1.1 or 192.168.0.1. See the label at the bottom of the router for details.

4. If the DNS server is not filled in, it will be automatically obtained from the gateway router (wired router). 8.8.8.8 and 8.8.4.4 are free gateways provided by Google. If you can access the QQ but cannot access the web page, the gateway may be blocked.

Step 3: set up wireless Internet access.
