I want to use this card to connect to a wireless lan at home. The card has an Atheros chipset. So I have installed the madwifi driver. First I jave tried to connect to the wireless lan over WPA-PSK. I did not connect. Then I have tried to connect to an open wireless lan. There I was successful but the I can't send or receive any data. A ping to the router returns the error message, that there are wrong data byte. Strange...from the ping data, it looks like the card fails to return some bits at a fairly regular interval. However, there are the things I would try, in order of most-likely to least-likely to help! 1. Disable G mode on the access point/router to force 'B' mode connection. Also, if possible, disable any 'turbo' mode options in the access point. Basically, we are trying to remove any data rates above 11Mbps. This does not work. 2. Try setting different channels on the access point. To get a quickly updating status on signal stregth and quality, you can use a command like: while sleep .5; do clear ; iwconfig ath0 ; done I have done this experiment. On all stages I got a Link Quality of ~40/94 and a signal level of ~-50 dBm. The ping does not work. 3. See if you get different results by pinging another host on the network. At all hosts the result is the same: wrong data byte by ping. 4. Remove IPv6 support from the kernel.. I try this. But it needs some time to compile the kernel and the depended projects like xorg-x11, qt, ssh, iputils, ... I will give you the results later. I doubt this is actually a conflict between the cardbus bridge and the G650 though. If that were the problem, I would expect lockups, lost interrupts, crashes, and so on. If this doesn't help, try browsing/searching/posting the madwifi-users list. I searched for packet loss which is where I got the ideas on #1 from. http://sourceforge.net/mailarchive/forum.php?forum_id=33958 The sourceforge website was down. I look at it later. Finally, you have my compliments for an excellent and thorough request for help! HTH. -Richard -- gentoo-user@gentoo.org mailing list

[gentoo-user] Acer Travelmate 524tx and Wireless lan PCMCIA: D-Link DWL-G650

I have bought a D-Link DWL-G650 108MBit PCMCIA-Wireless lan card. I have an Acer Travelmate 524tx. I want to use this card to connect to a wireless lan at home. The card has an Atheros chipset.

There I was successful but the I can't send or receive any data. A ping to the router returns the error message, that there are wrong data byte. I have figured out that the used PCMCIA-Card chipset (O2 Micro OZ6933 / 711E1) of the Acer Travelmate 524 TX might be not compatible to the Atheros chipset (or the used driver etc.). I tried to use madwifi and ndiswrapper. Both did not work. Can anyone help me? Has anyone accompished to get the card on this cardbus chipset running? Anyone an idea what I can do further? Here I give you some more detailed information. I hope, this are enough. If it is not, tell me what more information you want.
