It took me nearly half an hour.
The original residential broadband is a pppoe dial-up connection. When the vro is set to start DHCP, it sets itself to 192.168.1.1. Generally, there is no problem.
Today, broadband is migrated from Binjiang to Yuhang. The residential area is no longer in the pppoe mode, but in the dynamic IP Mode. After the wireless router is connected, the IP address is allocated as 192.168.173.1.
However, you cannot access the admin homepage. Disconnect the WLAN, reset, and wireless network connections to automatically obtain the IP address and DNS. The vro is reconfigured to 192.168.1.1. After the connection, access ADMIN.
The management page is normally accessed, but the WLAN is set to a dynamic IP address, and the IP address is never obtained.
You can directly connect to your computer using a network cable to obtain the correct IP address. Check whether the IP address of the gateway is 192.168.1.1 and the IP address of the local machine is 192.168.1.3. Is it because the IP address allocated by the bandwidth is in the same subnet as the router?
Set the vro address to 192.168.2.1. After restart, you can access the admin homepage and check that the dynamic IP address has been obtained. QQ has automatically connected to the Internet.
