It should have Internet by default.
Yes. But does not have.
I am not sure what is wrong.
Can you make sure the subnet is not the same as upstream router?
Yes I make sure. Subnet is 192.168.9.x but upstream router is 192.168.120.x.
It is it allowed to access the router UI.
Laptop connects to Guest wireless on GL but go to 192.168.9.1 in browser is not possible.
I do not create Guest network by use GL UI. I use Luci because no one tell me how I can create in GL UI but I ask so many times where is “Repeater section” in GL UI that is say in doc.
I know is not problem with connection because LAN wire port on GL router have 192.168.8.x and this have internet. Only wlan1 no have internet.
