Vero 4K not staying connected to WiFi between reboots

The title sums up the issue I am currently having.

I have configured my wireless connection using the GUI (disable wired adapter, enabled wireless adapter, selected SSID, entered PSK, clicked Apply) but whenever I reboot the device it hangs on the boot screen until the “Wait for network” times out and forces the boot process to continue. So, once in, I’ll have to go back to the network configuration and manually click on the SSID to connect to the wireless network (no need to re-enter the PSK again).

Has anyone seen this in the past?

Thanks!

PS: Router is a Portal Wifi. All other wireless devices work flawlessly.
