Re: duration_id field in zd1211rw

Jussi Kivilinna — 2012-02-02T21:16:38

Hello again!

I tested the patch with pspoll check and concluded it works as it  
should. I'm planing to post your patch (+ pspoll fix) to upstream, so  
may I add your 'Signed-off-by' to it?

-Jussi

ps. patch attached.

Looking at vendor's zd1211 driver, it appears that duration_id is kept  
at zero for all packets except PSPoll. So following should work:

+       /* firmware computes the duration itself and needs the field set to 0
+        * at input for all packet types than PSPoll.
+        */
+       if (!ieee80211_is_pspoll(hdr->fc))
+               hdr->duration_id = 0;


Both are handled same for duration_id by vendor driver.

duration_id field in zd1211rw

Tomas Vanek — 2012-01-30T09:13:10

Hello developers,

first thank you for the rewrite of zd1211 driver.

I use a small x86 server currently with linux 3.2.1 and generic ZyDAS 
wifi ZD1211B 802.11g (USB ID 0ace:1215), fw 1.4
hostapd v0.7.3 is used for AP mode with WPA2 security. 6 wifi clients 
(ath and prism54 chips) connect without problems.

Unfortunately two notebooks with iwl5100 card cannot connect at all. 
Tested with both linux and Win7 on the notebook.
I also tested without security and iwl5100 didn't work again.

Hostapd log shows that association worked but EAPOL frame is not replied 
by iwl:

Re: Patch for new kernels UP to 2.6.33 and higher

Jussi Kivilinna — 2011-11-18T13:35:54

Hello,

Master mode works, but not same way as with zd1211. You need to use 'hostapd':
  http://linuxwireless.org/en/users/Documentation/hostapd

Quick copy-paste from that page: "The mac80211 subsystem moves all  
aspects of master mode into user space. It depends on hostapd to  
handle authenticating clients, setting encryption keys, establishing  
key rotation policy, and other aspects of the wireless infrastructure.  
Due to this, the old method of issuing 'iwconfig <wireless interface>  
mode master' no longer works. Userspace programs like hostapd now use  
netlink (the nl80211 driver) to create a master mode interface for  
your traffic and a monitor mode interface for receiving and  
transmitting management frames. "

0x0ACE 0x1215 should bind to the zd1211b kernel module (the vendor driver builds two kernel modules, zd1211 and zd1211b). That said, compat-wireless is probably the way to go...

Hello,

zd1211rw gained master mode support in 2.6.39. For older kernels I  
recommend you to try compat-wireless (backports of latest wireless

Hi Michael,
Thanks for your reply
Main line driver(zd1211rw) doesn't support master mode. It can't use for AP. 
I need it to test old chips dongles. And of it possible to improve some 
aspect of code.

Re: Patch for new kernels UP to 2.6.33 and higher

Michael Tokarev — 2011-11-17T08:25:07

Maybe you should use zd1211rw instead, which is part of the stock
(mainline) kernel, does not require any patches to compile, and
also supports this device?

zd1211 in monitor mode only beacon

吴斌斌 — 2011-11-14T13:40:19

Hi all,
my usb wireless card' chip is zd1211, but i can only get beacon and probe
request in monitor mode. Has anyone ever faced such problem?
My PC's system is ubuntu 11.10. These are my commands:

*ifconfig wlan0 down
iwconfig wlan0 mode Monitor(without error output)
ifconfig wlan0 up*

After these, i retype in "iwconfig" to check is the mode was set correctly.
It was in mode Monitor actually.
But in wireshark, it can only capture beacon and probe request/response.

Have i done anything wrong?

Thanks for help.

ZyXEL dongle Connection timed out Ubuntu 10.04

Fernando J. Iglesias García — 2011-09-23T08:28:08

Hi,

I am facing a trouble trying to use my *ZyXEL* 802.11g Wireless USB Adapter
model *G-202* in my system with Ubuntu 10.04. My hardware system is a
RoBoard100 <http://www.roboard.com/RB-100.htm>, the version 10.04 of Ubuntu
installed just has command-line support. When I installed the operative
system I had to change the kernel in order to work in the RoBoard. The
actual version of it is:

*$ uname -r
2.6.34.10-vortex86-sg
*
The problem is the following. The RoBoard detects the wireless dongle as I
can see in the *dmesg* log, using *lsusb* or simply listing my devices with
wireless extensions with *iwconfig*. As I find it normal, when I plug in the
dongle, the interface is down since I have not yet anything in my
/etc/network/interfaces in order to set it automatically. When I try to set
up the device I obtain the following:

*$ ifconfig wlan1 up
SIOCSIFFLAGS: Connection timed out*

If I insist a couple of times more with the same command, I end up
obtaining:

*usb 2-1: USB control request for firmware up

so the signal should be in [-127 to 0] ?!?
what is iw doing if there is no rssi value given? network manager shows some tiny signal.....

This usually doesn't work. Just setup hostapd and it will setup master mode itself.

Gábor Stefanik — 2011-06-17T18:00:03

See http://wireless.kernel.org/RTFM-AP

And in general, mac80211 doesn't really support setting interface
modes through wext (iwconfig) - use nl80211 (iw) instead. But even
that won't get you AP mode; see above.

Re: firmware timeout issues (error -110)

Jussi Kivilinna — 2011-05-29T16:39:22

Hello!

This is interesting bug. The device actually presents itself  
differently to host depending if it's running either USB 1.1 or 2.0.  
As I tested zd1211rw AP-mode only on USB 2.0, result was that zd1211rw  
expected to always see device as it seen on USB 2.0. On OHCI-host this  
triggers error in ohci_hcd when driver tries to communicate to device  
(and correct error message appears only with zd1211rw debugging  
enabled).

Patch attached fixes the problem.
