In this case, if everyone has a computer and it is concentrated in a training room, then use four wireless APS and a better wired router. 200-300 yuan's armored routers may not be enough, let alone 100 multi-yuan home routers. If all the wireless routers are used for networking, it will definitely be much more complicated. It is easier to use wireless AP directly. 100 can buy an ordinary wireless AP for more than a few dollars. To afford a router with 200 computers, you need an enterprise router. It is estimated that it will cost at least one or two thousand yuan, because we should leave some spare time. (an enterprise router+at least four wireless APS, and the SSID and security settings of each wireless AP should be the same, so as to realize seamless roaming. )

If your 200 computers are scattered in different rooms, it depends on the actual situation, but generally speaking, it is better to use wireless AP. Multiple wireless routers are distributed in the same LAN. If you want to get rid of long-term IP conflicts, you need to change the router IP one by one, and you need to turn off DHCP (in this case, it is actually used as a wireless AP). )
