Experiences in setting wireless routes for Optical cats

My experiences on setting wireless routes for Optical cats recently encountered such a problem when debugging wireless routes for a relative, this gives me a better understanding of wireless routing !!! They used to dial up the Internet through cat and wireless connections. After the migration, the network cable was upgraded to the optical fiber, 'Don't have a cat. 'I inserted the network cable to the Wan port according to the original connection method, then, you can use wireless signals to access the Internet. Curious, I inserted the network cable to the Lan port and found that I could access the Internet, but other laptops and mobile phones could not access the Internet, nor could I enter the route (the route was used as a switch ). Solution: insert the network cable to the Wan port of the route, and then set the route. I will not talk about the route entry method. After Entering the network, select the network parameter and set the Lan IP address, it cannot be in the same CIDR block as the IP address of the network. My IP address belongs to the 1 CIDR block, so the IP address of the Lan I set is 192.168.2.1, and then set the wireless password, it is emphasized that dialing is not required! Restart route. Successful! My experience: Later I learned that the cat is not without a cat, but is not installed here. It may be in the external chassis, and the cat comes with the wireless routing function, that is, you can directly connect to the Internet without routing, but only one device can access the internet. Therefore, we must bridge the two routes together using the wireless routing method, however, if the IP address is in a CIDR block, a conflict occurs. Therefore, the wireless CIDR block after bridging must be changed!
