Hi Gatson,
Try toggling Airplane Mode, and verifying you're connected to the correct network. Then try disabling firewalls or VPN if you have any. If problems persist, you can run the network troubleshooter, reset the Wi-Fi adapter via Device Manager. If your Wi-Fi driver is outdated you may download the OEM driver for your surface. https://support.microsoft.com/en-us/surface/download-drivers-and-firmware-for-surface-09bb2e09-2a4b-cb69-0951-078a7739e120. Hope this helps.
Best,
Jeric.
