Second, you need to know the setting information of the router at the next higher level, such as whether DHCP is turned on. For example, the information of the router at the next higher level is192.168.0.1/24, and DHCP is turned on. From192.168.1.100-192.1.199, we know that the IP address of the router at the next higher level is from/kloc.
A: One is dynamic acquisition and the other is static acquisition. Selecting dynamic acquisition will automatically acquire the IP in the DHCP allocation interval of the router at the next higher level. Using static collection, we can set the IP manually.
subnet mask
Gateway, DNS, etc. For example, we can set the IP address to an IP other than the IP automatically assigned by the superior router DHCP, but we cannot set the gateway. For example, we can set it between 2-99 or 200-254 and find any IP. The subnet mask is 255.255.255.0 of Class C, and the gateway is 192.6438+068.66. In this way, as long as the network segments between the superior router and the secondary route are different, and the acquisition method follows the information of the superior router, there is no problem.
B: Another way is to use this secondary wireless routing router as an AP, that is, to turn this router into a wireless switch. Just disconnect the network segment of the secondary router from the superior router, then turn off the DHCP service of the secondary router, connect the LAN port of the superior router to the LAN port of the secondary router, and connect nothing to the WAN port of the secondary router, so that the secondary router becomes an AP switch.
