Ask good people to talk about why Xiaomi's mobile phone is connected to wifi but can't get online?

There may be several reasons for being able to connect to WIFI but not surfing the Internet:

1. The network parameters of the wireless router are set incorrectly, so it is impossible to dial the local equipment of the ISP operator and access the Internet;

2, broadband line failure, the router can not dial the ISP operator's office equipment, unable to connect;

3. The broadband DNS server can't provide domain name resolution service for some reason, and its external phenomenon is similar to the inability to access the Internet, which is easily confused as the network is blocked;

4. Broadband is disconnected by ISP operators due to the expiration of the tariff, and it needs to go to the business hall to pay for renewal;

5. IP address filtering is set in the router, and the IP address obtained by the mobile phone is in the IP section where Internet access is prohibited;

6. The router has started timed dialing, and the current time is not within the time period of automatic dialing;

7. The modem power is off, and the router cannot dial the network;

8. The network cable connecting the modem and the wireless router is out of order, such as being bitten by a mouse or squashed by furniture or having poor contact with the crystal head, which makes the router unable to connect to the network.
