The answer is as follows: To set Huawei WiFi dual-band in one, you can perform the following steps:
1. First, open the management page of your Huawei WiFi router. You can type your router's IP address, usually 192.168.1.1, into your browser and press Enter.
3. On the router management interface, find the wireless network Settings option. It can usually be found under the TAB \"Wireless Settings,\" \"WiFi Settings,\" or similar.
4. On the wireless network Settings page, you should be able to see an option that may be called \"Band,\" \"Dual-Band in One,\" \"Dual-Band Mode,\" or something similar. Select this option.
5. On the dual-band Settings page, you can choose to combine the 2.4GHz and 5GHz bands into one wireless network, or split them into two separate wireless networks. Select the option to merge the two bands.
6. After confirming the Settings, click the Save or Apply button to save your changes. The router may reboot to apply the new Settings.
Please note that different models of Huawei WiFi routers may have different interfaces and option names, so you may need to make some adjustments depending on your router model. If you encounter any problems, refer to the user manual of the router or contact Huawei customer service for help.
Log in to the router management interface from the computer or mobile phone, and turn on the \"WiFi merge switch\" or switch in WiFi Settings. Click \"OK\" in the pop-up dialog box to complete the merge.
