How to setup a guest wifi

Hello,
We're working on your problem. Please be patient.

Hi Henry_Chinson!
I hope I can give you some ideas, and maybe you can break the problem apart and analyze it.
1. You can create two ssids. One for internal wifi and one for guest wifi.
2. Create two different network segments so that the gateway can distribute different IP addresses to terminals.
3. Create an ACL and a traffic policy to prevent guests from accessing the internal server through Wi-Fi.

Hi, friend!

If you have configured the first SSID and need to add the second SSID, perform the following steps to add the SSID:
1. Click Wizard. The Wi-Fi Signal Settings page is displayed.
2. On the Wi-Fi Signal Settings page, click New. The Basic Information Configuration page is displayed. Select or enter the parameters (configure the wireless name and password) in sequence according to the device description. Click Next. The Address and Rate Configuration page is displayed.
3. On the Address and Rate Configuration page, set or set parameters based on the device description, and click Finish.

Thanks your reply. When I create a new ssid with a new segment(eg:192.168.10.1). But this ssid cannot go internet. Did I need create a routing rules. May I an example! Thanks

usually for that purpose I create 2 vlans in 2 SSIDs i.e.
1. create 2 vlans
SWITCH
STAFF vlan10
GUEST vlan20

2. create 2 ssids
AP
STAFFSSID vlan10
GUESTSSID vlan20
connect ge0 AP to trunk port on the switch

3. create acl in switch
-allow vlan10 to servervlan and internet
-allow vlan20 to internet only

NOTE:
I never tried myself in Huawei but I ever tried in Cisco
