Red Hat Bugzilla – Bug 427528
assist NetworkManager in supporting hidden SSID networks
Last modified: 2009-06-19 22:01:43 EDT
Current wireless extensions API does not give sufficient information for NM to
know how to configure wpa_supplicant to support association with wireless
networks that do not broadcast their SSID in beacon frames. A simple patch
has been merged upstream which extends the API to provide the necessary clue.
This bug is intended to cover backporting of that patch on top of the wireless
patches already pending for 5.2.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
Have implemented this in upstream NetworkManager upstream trunk and stable
branches, can easily backport this to RHEL5.
Testing NetworkManager packages available here with the scan capability
Please attach the output of "cat /var/log/messages", especially the first 10
lines or so containing the word "NetworkManager". You should see some text like:
NetworkManager: <information> eth1: driver does not support SSID scans
if the driver does not support SSID scans or if the kernel does not have the
patch from this issue.
You should see something like:
NetworkManager: <information> eth1: driver supports SSID scans (scan_capa 0x01)
if the driver _does_ support SSID scans and the kernel has the correct support
This is the kernel bug -- get your own! :-)
I retested the hidden ap case with NetworkManager test package on kernel
jwltest.50.i686 from Linville. NetworkManager works fine on connecting hidden AP.
In /var/log/messages, I can see the information that "driver supports SSID scans".

Jan 17 13:55:55 jane-sr NetworkManager: <information> wlan0: Device is
fully-supported using driver 'iwl4965'.
Jan 17 13:55:55 jane-sr NetworkManager: <information> wlan0: driver supports
SSID scans (scan_capa 0x01).
More log from /var/log/messages will be attached, in case you still need it. :)

Tested the kernel 2.6.18-72.el5, testing NM package works fine on connecting
On RHEL5.2-sp4, NetworkManager works well w/ connecting hidden AP. Verify this bug.
