Thanks for that.
I have now read further and seen that what you say makes sense and I will give up on the idea of hiding the SSID
I still think that hiding the SSID is still a good security idea. Sure encryption is much more important. And hiding the SSID on a work network with dozens/hundreds of clients is pointless as your non-broadcast id is broadcast by all of those clients looking for an AP. But in a home with < 10 wireless network devices? Most of the time they're either connected (and then they'll stop shouting out your hidden id) or switched off. So I don't imagine they're broadcasting your id very often. Sure, if you want to sit outside my house all day, every day, you'll eventually get my id. But hiding it is, I think, a clear statement that uninvited guests are not welcome.
And a truly determined hacker will still find a 'hidden' SSID anyway. The good news is that personal WLAN's often don't extend too far from the property and the potential gains are irrelevant for the time required to trap anything useful.
As others have said, hiding the SSID is a good additional layer of security but it will only deter the Skript Kiddies.
Hub2 does offer the option though
|Hide wireless network name (SSID)|
|Type of wireless encryption|
Sometimes people don't want to broadcast their SSID - it should be their choice.
I live in a built up area next to a hotel and I don't want people pinging my SSID.
This is a bad and uncessary flaw on the HH3 - I'm going to swap it for a 2701 hub which I've found much more reliable.
