I use associate=0 with smole workaround: diff --git a/drivers/net/wireless/ipw2200.c b/drivers/net/wireless/ipw2200.c index dcce354..92583c6 100644 --- a/drivers/net/wireless/ipw2200.c +++ b/drivers/net/wireless/ipw2200.c @@ -7582,7 +7582,7 @@ static int ipw_associate(void *data) if (!(priv->config & CFG_ASSOCIATE) && !(priv->config & (CFG_STATIC_ESSID | - CFG_STATIC_CHANNEL | CFG_STATIC_BSSID))) { + CFG_STATIC_BSSID))) { IPW_DEBUG_ASSOC("Not attempting association (associate=0)\n"); return 0; } becouse networkmanager do not set channel=0 to be compartibel with other drivers. Are there any better solution?
