https://bugzilla.novell.com/show_bug.cgi?id=421880 Summary: Can't connect if wireless SSID not broadcast Product: openSUSE 11.0 Version: Final Platform: i686 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: nick.battle@uk.fujitsu.com QAContact: qa@suse.de Found By: Community User Configuring a WPA wireless client to connect to an AP that doesn't broadcast its SSID used to work perfectly in openSUSE 10.3, but 11.0 fails to add "WIRELESS_AP_SCANMODE='2'" to the ifcfg file, which causes the WPA supplicant to fail to form an association. Details: ipw2200 device, configured for WPA_PSK security, AP's BSSID (and SSID) set via Yast. Subsequently adding WIRELESS_AP_SCANMODE='2' to the ifcfg file and stop/starting the interface cures the problem. The Yast in 10.3 appears to add the scan mode line, which then works first time.

I keep notes after every installation, and my 10.3 notes say, "To get the wireless working, you need to be careful at setup. First, you need to explicitly add the wireless AP in the configuration (00:16:B6:DA:77:AB), as we have no SSID broadcast. Second, you need to explicitly add DNS as 192.168.1.1, as well as adding the default route to 192.168.1.1. It may not be possible to add the default route during installation(?). You can from YaST in the Network/Routes section." I don't *remember* adding the scan mode by hand, but I haven't tried a 10.3 install/config of the wireless since either. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't *remember* adding the scan mode by hand

On the other hand, the "tips and tricks" link in the openSUSE forums was dated Aug 2007... I *do* remember having to play about with Yast several times to get the correct settings. I wonder whether it is possible to add the scan mode value by some sequence of Yast actions, and once it's there it stays there? If 10.3 Yast never adds it, we'll have to put this one down to my aging memory - though the bug still stands of course.

...

Could you please try if "iwlist eth1 scan essid your_essid" finds your access point?

That's on 11.0 without the scan mode line? OK, I'll try - though if the SSID isn't being broadcast, I can't see how this can find anything, surely? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As "hidden" networks are not specified in 802.11 most vendors implement it in the following way: Neither the beacon frames nor probe responses contain the SSID. However if a client knows the SSID it can send a probe request for a specific SSID to which the AP will answer (that is what "iwlist ... essid ..." does). Hence a client which knows the SSID is able to scan for APs with that SSID even if they do not broadcast its SSID. Furthermore a client that does not know the SSID can still listen to probe responses to foreign clients in order to reveal hidden networks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It does appear to work as you explained, ie. an initial scan without the essid parameter shows a hidden network, but then performing an iwlist with the ESSID to probe, a second(?) cell appears showing the same network, but with the ESSID set. Sometimes there is a delay before the named cell appears - perhaps the negotiation happening? # iwlist eth1 scan | grep ESSID ESSID:"<hidden>" ESSID:"DOUGAL" ESSID:"BTHomeHub-9A01" ESSID:"BTHomeHub-0CDF" # iwlist eth1 scan essid Wibble | grep ESSID ESSID:"<hidden>" ESSID:"DOUGAL" ESSID:"BTHomeHub-9A01" ESSID:"BTHomeHub-0CDF" ESSID:"Wibble" In detail: Cell 04 - Address: 00:16:B6:DA:77:AB ESSID:"<hidden>" Protocol:IEEE 802.11g Mode:Master Channel:3 Frequency:2.422 GHz (Channel 3) Encryption key:on Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 6 Mb/s; 9 Mb/s 11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s 48 Mb/s; 54 Mb/s Quality=64/100 Signal level=-62 dBm IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : TKIP Authentication Suites (1) : PSK Extra: Last beacon: 176ms ago Cell 05 - Address: 00:16:B6:DA:77:AB ESSID:"Wibble" Protocol:IEEE 802.11g Mode:Master Channel:3 Frequency:2.422 GHz (Channel 3) Encryption key:on Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 6 Mb/s; 9 Mb/s 11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s 48 Mb/s; 54 Mb/s Quality=44/100 Signal level=-59 dBm IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : TKIP Authentication Suites (1) : PSK Extra: Last beacon: 168ms ago I get the same behaviour on 10.3, incidentally. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

AFAIK sysconfig uses ap_scan=1 and scan_ssid=1 as default which should work fine with ipw2200. Instead of setting "WIRELESS_AP_SCANMODE='2'" through yast (which is only a workaround for buggy drivers) we should focus on why the connection fails with the default scan mode.

Nothing appears in /var/log/messages when I do this. I tried with DEBUG=yes and DEBUG='yes'. What I do see in /var/log are messages in "warn" and "wpa_supplicant.log".
