Our school computer room, some can't get to the Internet, are all manually set the IP address, if change after this period of other IP address can be used, for example, this is the IP address of the computer 192.168.1.3, can't get to the Internet (network and showed exclamation mark), but with 192.168.1.5 is ok

CodePudding user response:

Why don't you do the IP and MAC binding? May be artificially modified part of the IP conflict, don't give the client the administrator permissions,

CodePudding user response:

Is it possible to be routers have the ACL control, limiting the part of the IP can't surf the Internet

CodePudding user response:

Perhaps because IP conflict,

CodePudding user response:

ARP binding MAC address and router set inside the DHCP fixed at MAC address assign IP core can be done,

CodePudding user response:

Routers do static MAC binding, specific can see into the router

CodePudding user response:

In some places the signal is weak

CodePudding user response:

Ping 192.168.1.3 this address, most of the probability is an IP address conflict,

CodePudding user response:

1, may be IP address and MAC address binding
2, may be divided into the subnet
3, could be divided into the VLAN
4, may be the ACL banned
6, may be IP address conflict
.
