For the WPA1/2PSK (my home network) I was able to get them to connect by unhiding the ESSID and joining, and then hiding the network again. The WEP/LEAP network is no worky as I cannot unhide it. I have tried using iwconfig to set the ESSID pre-emptively but that didn't work either. It appears to error out after the authentication is complete so there may be another setting that I am not aware of (I'm not very savvy on the Linux wireless front.
A few weeks ago I studied the behaviour of NetworkManager with hidden WPA networks. Having found that NetworkManager 0.7.2 could not connect to my WPA network until I configured my router to broadcast the network name (SSID), I then configured my router to stop broadcasting the network name, i.e. I made the WPA network a hidden network again. I found that NetworkManager could then connect to the hidden WPA network.

If I understand correctly from the following exchange of posts with a NetworkManager developer, it seems this functionality is not a bug in NetworkManager; it is intentional: Cannot connect to wpa/wpa2 network with hidden SSID.
Dan Williams wrote:The supplicant isn't able to probe-scan to find your AP because it doesn't have the information yet to be able to do so. Once you've successfully connected, NM will cache the AP's BSSID and recognize that AP from the scan list and try to reconnect automatically. But the first time has to be manual, because otherwise there's no way to find the AP since it's trying to hide.

Hiding isn't actually a useful method of increasing security, since the AP's beacon and BSSID are always available in probe responses; so anyone can actually get the SSID irregardless of whether the AP is broadcasting that information in its beacon.
See also the following openSUSE thread about the same functionality: Cannot connect to a hidden SSID and the following SLED thread: Hidden Access Point: Cannot connect to wireless.

Finally, it seems that the functionality is the same in Windows Vista -- see the thread: Vista - Can't connect to router with hidden ssid.

So it looks like it is by design. I'm not sure I understand a post in each of the two above-mentioned SUSE threads, but it looks like there may be a parameter that you can set in one of the networking configuration files that lets you override this functionality and allow a PC -- if one knows the network name and password -- to connect to a hidden network that has never broadcast its network name. But I'm not sure yet: I need to do some more googling/reading.

But....kudos to the developers. I've never had a more stable experience in Sabayon or any of the Gentoo derivatives. I used to come into it expecting to have to do some aggressive maintenance on a routine basis and would therefore make sure I had enough time to do so. Any more, I'm surprised, especially in the entropy world, if anything more than a normal update is required. For me, it just works, and works well!

Well I use for work. My main job is developing php pages.

I need. Kate, Kmail, Skype, firefox, dual desktop (with different res and ati card) and some firefox extensions.

All of them work flawlessly.

Last 2 years I had Kubuntu. After each relase I lost some of abilitys. (dual desktop, then firefox wont work some extensions)

Sabayon was much better. It fast and stable except that f*** pulseaudio. I remove it now I'm mosty happy. Except that network management thing always using default thing.

I have installed Sabayon 5.1 KDE and have the same problem. My home wifi network is hidden and not recognised. It's 100% a bug, using Ubuntu 09.10 I have no problems to connect, it simply asks for network name and passphrase. XP and Vista have no problems too.
