Wifi-Link V3.3.0 dont change/safe AP settings

[GobNik]

When I try to change the AP settings from the Wifi-Link V3.3.0, nothing will be changed/saved.
Try it with 2 browser: Firefox & Chromium.
Restart the Wifi-Link dont work.

I want to change the AP Name & password & encryption.
Its not a good thing, to switch off the encryption in the default settings.

I did a firmware update to 3.3.3.
But I cant change the AP Settings: SSID & AP Password & AP Auth Mode (after switching to "Show").

Than I tried a little bit and saw an error message on top of the configuration site, someting with "SSID...". Cant read it completely, because the error message disapeared to fast.
I let the SSID name unchanged and try to set only a password and AP Auth Mode. But that dont work. Than I tried only to change the AP Password and it worked! After that, I change the AP SSID and it worked too. And than I could change the AP Auth Mode.

Now all my changes are applied. But I think, there is something a little bit strange with the configuration of the Wifi-Link AP

Changing SSID :

The error message was: "SSID not valid or out of range" - means that the name for the SSID must be at least have 8 characters (like the AP password).
Now I could change the SSID.
