Why can't the wireless network find the DNS and port?

Why can't the wireless network find the DNS and port? [Copy link]

My laptop can search for other people's wireless routers around me, but they are not encrypted. I could access the Internet before, but I can't access it anymore. The detection reports of QQ and MSN are as follows: DNS is incorrect, IP cannot be resolved; and the port is also incorrect. Do you think there is a way to solve this problem? (This behavior is a bit unethical, but I am currently poor, so I will save as much as possible and only check the Internet occasionally.) And why can't I capture packets using ethereal? Is it because ethereal does not support my wireless network card? Thanks a lot!

Haha, have you updated the wireless link to see if they have been encrypted? Also, check whether the automatically obtained IP address and DNS are correct. Also, you can ping the gateway. If the ping fails, it means that the address you got is wrong, and there is definitely no way to connect to the wireless router. As for the packet capture problem, normally it can be captured as long as it is Ethernet. . .
