Networkmanager does not find a wireless network which is set to not broadcast ssid

[iamhimay]

Binary package hint: nm-applet

I could not connect to a network that had the router set with "wireless ssid broadcast" set to off. As soon as that setting was changed in the router I was able to connect. Changing it back to non-broadcasting while connected resulted in immediate loss of connection. I used NetworkManager in Edgy x86_64 and did not have this issue with the same hardware (Thinkpad t60 with Atheros wireless using Madwifi in linux-restricted).
I am also wondering if this is an issue with madwifi, because I was using madwifi svn when I had success finding the unbroadcast ssid network.

I tried first with standard installed kernel, then switched to low latency (my default). Both produce same result.

I have a similar problem on i386 atheros card will not detect a cloaked system. By associating using "sudo iwconfig ath0 essid "password""first it works?

[Hendrick Musche (hmu)]

Same here. Network-Manager *very* rarely connects to my hidden university network. Setup with iwconfig et al works fine, but no network-manager. wpa_gui tells me it tries to associate, but never achieves to do so. I'm not sure where the issue is located, might be network-manager, wpasupplicant or the madwifi modules, or a random combination of those.

Can this be verified on feisty?

It's the same issue as https://bugs.launchpad.net/network-manager/+bug/89493
The problem occurs on different wireless cards, so I don't think problem is on wireless drivers side.

I got the same problem under atheros card - when I'm turning off essid broadcasting in Acess Point Network Manager can't connect.
But when I run while NetworkManager is trying to connect:
<code> sudo ifdown ath0; sudo ifup ath0</code>
it's getting connected.

There wasn't such problem in Edgy.

I can confirm that NetworkManager will not auto-connect to a non-broadcast SSID with WPA on Feisty.

To summarize, if my WPA wireless network is set to non-broadcast NetworkManager will not connect upon boot/login If I manually re-enter the connection information it will connect (but the information needs to be entered again upon reboot).

I had the same issue on OpenSUSE 10.2 (but just now figured out what was going on).
