Hello!
My iwl3945 device cannot associate to Linksys BEFW11S4. The AP reports
code 18 (unsupported rates).
I tried the current master branch from iwlwifi repository with the
current wireless-2.6/everything kernel patched by mac80211 10.0.0, and
it still exhibits the problem.
It turns out the driver sends CCK rates as extended and OFDM rates as
"non-extended":
Tagged parameters (23 bytes)
SSID parameter set: "WTEST"
Tag Number: 0 (SSID parameter set)
Tag length: 5
Tag interpretation: WTEST
Supported Rates: 6.0 9.0 12.0 18.0 24.0 36.0 48.0 54.0
Tag Number: 1 (Supported Rates)
Tag length: 8
Tag interpretation: Supported rates: 6.0 9.0 12.0 18.0 24.0 36.0 48.0 54.0 [Mbit/sec]
Extended Supported Rates: 1.0 2.0 5.5 11.0
Tag Number: 50 (Extended Supported Rates)
Tag length: 4
Tag interpretation: Supported rates: 1.0 2.0 5.5 11.0 [Mbit/sec]
The association request captured by WireShark is attached.
I tried swapping WLAN_EID_SUPP_RATES and WLAN_EID_EXT_SUPP_RATES in the
sources, but it didn't work. Maybe mac80211 rewrites the request, I
don't know.
Also, iwl3945 refuses to scan more than several times, and the only
workaround is to reload the module. Maybe the association failure
triggers that. If it's not a known problem, I can look closer.
