Hi, I'm Randy. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Tap or click on the wifi symbol on the Zenbook screen, then let me know what is listed there beside your wifi network name(BT) please.
It is possible that you have entered the wireless security key incorrectly, the network name (SSID) and wireless key is on a label on the Hub. For example, the SSID is BTHomeHub-xxxx and the wireless key is abc123de45.
to forget a wireless network in Windows 10, you can use the Settings app. To begin, open Settings, Then, click or tap on Network & Internet.
Tap or click Network & Internet is Wi-Fi,
Next, in the Wi-Fi section from the right pane, click or tap on Manage Wi-Fi settings.
The Manage Wi-Fi Settings window contains two sections: Wi-Fi Sense and Manage known networks. Scroll until you get to the second one: Manage known networks.
Select the wireless network BTHUB. Windows 10 will display two options for it: Share and Forget. To delete the network's stored profile and forget all its connection details, click or tap Forget.
Once you do that, Windows 10 will immediately remove the wireless network from the list of known networks.
Then you can connect to it again and reenter the wireless password.
okay, which BT hub do you have? 5,4,3,...
Click on the blue link below, it has the images.
Okay. on the Hub 3 the network name (SSID) and wireless key is on a plastic tab that pulls out from the back of the Hub. The information may also displayed underneath the Hub.
What does the label have as the ssid and wireless key?
The wireless password ***** you need for wifi on the zenbook is listed as the wireless key on the label.
Are you on a computer now that is connected to the BT hub internet?
okay, check the zenbook and make sure that the caps is not on.
It should say connected/secured on the wifi connection.
I was just making sure the wireless key was entered correctly.
Try disconnecting the power to the hub for 1 minute, then reconnect the power, then wait 2-3 minutes, then try connecting again with the zenbook
okay. Did you try the power reset on the hub?
