Hello,
I recently got an A-LINK 54Mbit/s USB stick, which is recognized as
follows in 2.6.20-grade kernel (actually 2.6.20-1.rt2.0111 on FC6):
zd1211rw 2-2:1.0: firmware version 4725
zd1211rw 2-2:1.0: zd1211b chip 0ace:1215 v4810 full 00-02-72 AL2230_RF pa0 g--N
zd1211rw 2-2:1.0: eth1
SoftMAC: ASSERTION FAILED (0) at:
net/ieee80211/softmac/ieee80211softmac_wx.c:306:ieee80211softmac_wx_get_rate()
SoftMAC: Associate: Scanning for networks first.
SoftMAC: Associate: failed to initiate scan. Is device up?
ADDRCONF(NETDEV_UP): eth1: link is not ready
...
I'm having some issues getting it to work properly. Specifically,
during the normal FC6 ifup sequence, the card stays for a LONG time
(at least a minute) in ESSID:"S" state even if the ifup scripts give
it a specific ESSID, like follows:
eth1 IEEE 802.11b/g ESSID:"S" Nickname:"zd1211"
Mode:Managed Frequency:2.412 GHz Access Point: Invalid
Bit Rate=1 Mb/s
Encryption key:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
The last three lines of dmesg are:
SoftMAC: Associate: Scanning for networks first.
SoftMAC: Associate: failed to initiate scan. Is device up?
ADDRCONF(NETDEV_UP): eth1: link is not ready
The ifup scripts start a DHCP client, but IP layer doesn't work yet
but the interface is up:
# ip l l dev eth1
19: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen
1000
link/ether 00:02:72:5a:12:55 brd ff:ff:ff:ff:ff:ff
However, if I manually issue "iwconfig eth1 essid [ESSID]" command
while DHCP client is running, the card starts to work OK. Otherwise
DHCP client doesn't finish, and the interface stays in NO-CARRIER
state.
Also, if I manually do 'ifconfig eth1 up' before ESSID is set, it'll
work without problem.
In FC6, in normal circumstances, link is configured 'UP' only after
DHCP client has run or IP address has been configured. Other wireless
drivers also work with this sequence. Is there something different in
zd1211rw that setting ESSID doesn't work unless link is UP?
