DWL-G122 802.11g rev. B1 / WEP / 1Mbps

Could not connect with either of these drivers from DWL G122 rev B1 to SMC 7004 VWBR where I had to set the 1Mbps transmission and basic rates in order for the other machines to connect to the access point.
(a) rt2500usb from Debian unstable 2.6.26-1-686 (version 2.6.26-11)
(b) rt2570-cvs-2008120722.

With the former driver, I was getting the "authentication frame received but not in authenticate state" message,

Code:

With the latter, I saw "AUTH - AuthTimeout" messages (see the attached file rt2570-debug31.txt).

Here is my /etc/network/interfaces for the interface:

Code:

iface rt inet static
        address 192.168.2.172
        netmask 255.255.255.0
        network 192.168.2.0
        broadcast 192.168.2.255
        gateway 192.168.2.1
        dns-nameservers 192.168.2.1
        wireless_mode managed
        wireless_essid YY
        wireless_ap 00:04:E2:8E:86:AA
        wireless_key s:XXXXXXXXXXXXX
        # wireless_channel auto
        wireless_channel 6
        wireless_bit 1M
        wireless_rate 1M
        up /sbin/iwconfig "${IFACE}" key open
        # up sleep 3; /sbin/iwlist "${IFACE}" scan
        up sleep 3; /sbin/iwconfig "${IFACE}"
        # up /sbin/iwconfig "${IFACE}" ap 00:04:E2:8E:86:AA
        up /sbin/ip route add 224.0.0.0/4 dev "${IFACE}"

(To rename the interface of the former driver, I changed the name against the MAC address in /etc/udev/rules.d/70-persistent-net.rules. With the latter driver, I removed /etc/modprobe.d/ralink, added the MAC to /etc/mactab and ran /sbin/nameif).

Forgot to mention that the Windows XP pro drivers v1 and v2.04 worked intermittently. I could not find the cause of them stopping working.

The other Linux driver, adm8211, connects the ADMtek ADM8211 with my SMC access point using the same /etc/network/interfaces options just fine.

Hi ilgiz,

From the looks of the /etc/network/interfaces file you supplied, it looks like you're naming the rt2570 device "rt". Does "ifconfig" show an interface named "rt"? If not, have you tried adding "ifname=rt" to the modprobe command line? (Otherwise, the drive calls the interface "rausb0".)

Thanks,

Thanks, Vern. I did not try supplying the module's ifname option to modprobe and I removed /etc/modprobe.d/ralink because I manually rename the interface to "rt" using the "nameif" command that looks up my /etc/mactab.

I remember that the Debian's rt2500usb driver's interface was renamed by udev where I assigned it the same name, "rt".

Hi ilgiz,

While the driver can accept a command to change the MAC address it uses, it *cannot* accept a command to change its interface name. The nameif command doesn't enter into it here. Changing the interface name can only be done via the modprobe options I mentioned above, hence my questions.

Thanks,

Well, the "ip link list" command showed that the interface was renamed by my "nameif" invokation. And I think the attached log files show attempts to associate with the access point.

My conjecture is that there are 2 factors that make my case unusual:

(a) I limited the SMC access point to 1Mbps transmission and basic rates because it stopped being reachable by other machines at 11Mbps. I think this indicates some deterioration of the radio hardware in the first place. The access point is few years old.

(b) My D-Link USB stick showed unstable connectivity even under its Windows drivers. Recently, the link would re-appear only sporadically, in about 1 try out of 20.

Hi ilgiz,

Just took another look at the info in your original post.

is not issued by the legacy driver. Looks like you're using the nextgen driver. Maybe Ivo can help.

Thanks,

Interesting. I tried both. The other driver's logs should be in the attachment to the first posting. Thanks for your patience.
