Reported by: anonymous Assigned to:
Priority: minor Milestone:
Component: madwifi: driver Version: trunk
Keywords: wext wpa_supplicant hostapd Cc:
Patch is attached: 0 Pending:

Description

AMD Geode computer
Atheros AR5006X 5gig card
Linux 2.6.21.5-smp kernel
Madwifi-trunk-r3727
hostapd/wpa_supplicant 0.5.10

Using r3727, wpa_supplicant -Dwext will not connect to hostapd.
Using r3727, wpa_supplicant -Dmadwifi works fine.

use wpa_debug_wext.2.ath0. First one missed the bridge option to wpa_supplicant.

Hmm, the debug output with -Dwext does not seem to include a portion where an association attempt takes place. This may be an issue of itself, but it does not agree with the data from the wpa_supplicant log.

I've experienced that my three Microsoft Windows XP machines didn't have any problems connecting. The connection wasn't that stable but it worked. Though it crashed very often. My Linux machines aren't able at all to connect to my access point (using ndiswrapper, b43 module). I've tested this on three machines. What's the difference between the Microsoft Windows XP supplicant and the wpa_supplicant for Linux?

I am seeing the same here on my Ubuntu hardy with 2.6.25.3 + r3746, connecting to a netgear prosafe WG102 AP works only with -Dmadwifi ... it seem that the problem depends on the AP, since connecting to a Zyxel AP in another location workes fine ...

All my problems got fixed after changing the channel and adding this to the postup-function of /etc/conf.d/net: pastebin.ca/1057409 The interesting part is that there weren't any other access points on the previous channel. I've experienced that the higher the channel is, the faster is the connection. My best result was 2 MB/s. On my Microsoft Windoes XP and Linux machines the connection doesn't drop at all and the ping times (I was pinging the router - 192.168.0.1 - while testing all the different setups) are very good (< 1 ms). The ping latences are getting *much* higher (500 ms - 1s) when I'm transferring data but I could solve this by enabling traffic shaping to 0.5 ms - 1 ms. By the way, I'm compiled HostAP and MadWifi from source using the latest revisions. Here is my hostapd.conf: pastebin.ca/1057407

So, is the following summary correct: the reported issue was not caused by MadWifi, it's been solved and this ticket can be closed now?

06/30/08 21:03:17 changed by distupgrade@gmail.com

My access point is now running for three days without any problems. I hope, this has also worked for the reporter of this bug. If you ask me, you can close this ticket.

Well, distupgrade@gmail.com's problem may be solved, but mine is still an issue.
