Hi
What sort of errors are you getting? I've noticed a problem with the Wi-Fi password if set to something user defined, on revisiting the Wi-Fi page and changing a setting and applying it, all is okay, but revisit the Wi-Fi page and view the password and it shows the router password. This means on 'Applying' to save other settings on that page, the Wi-Fi password gets reset back to the router one.
Regards
Phil
