CodePudding user response:

More than 254 people on the Internet change the mask a little bigger, to 255.255.0.0, gateway or 192.168.0.1

CodePudding user response:

In theory can be connected to the normal, ping the router inside and outside network under the then confirm whether can pass

CodePudding user response:

Ask a question, the company has three layers of network structure, a new colleague's computer to join the domain, normal access to the Internet for a period of time (hours), suddenly can't get to the Internet, IP, DNS and gateway works, could you tell me what causes? Never reset or add strategy, not modified routers, firewalls, domain and so on all parameters, other older employees to normal,

CodePudding user response:

Gateway, DNS Settings look right

CodePudding user response:

Manually after the IP can also ping?
Can ping TongWai net?

CodePudding user response:

This theory can mask the gateway through you can check the computer DNS is correct

CodePudding user response:
