@autumnwalker, the sorting order is correct, but it sorts only the hostnames visible on the page.

You can check this by showing 100 entries per page and then click once to the hostname header to sort in ascending order and a second time to sort in descending order.

Technical background: the sorting happens in Javascript and not in the server, thus it is restricted to the current page content.

I recommend to use the »Last seen« selection box to narrow down the scope to the timespan you're interested in. This will give a much better overview than listing all entries (default).

@autumnwalker, for me it does change the behavior:

Unknown is a NULL WiFi hostname, it's the empty string.

Then names starting with an uppercase letters follow the empty string.

Then names starting with a lowercase letters follow uppercase ones.

When reversing sort order, it's exactly the other way around.

Ah! That's exactly what I am seeing here - the upper and lower case had thrown me off.

Yes, it's obviously ASCII sorting order, not lexicographical (dictionary) sorting order. You're right that this can be confusing.

jonas, please could you add this as a feature request to use lexicographical sorting order to the new Omada SDN controller?

Would make sense IMO.
