Vera 3 Net & Wifi settings stuck

When I try to change the settings on my ‘Net & Wifi’ tab, the Vera unit reverts back to the old settings. I can’t seem to change them. Is there any other way to change these settings without using UI5.

I don’t know if this is relevant, but a few weeks ago, I tried changing the Wifi channel to 13. UI5 complained that it couldn’t use Ch13 for the access point and switched the WifFi off. I now can’t do anything with it. Its the same for all settings on that page - none of them work.

I’m sure I’m setting it correctly - I make the changes, click ‘Save and apply’ at the bottom and refreshed once its finished.

Any ideas?
