DWL-520 Problems

My D-Link DWL-520 is having a problem associating with my access point (ap has no access controls - fully open system). It used to work just fine, for about a month, then something happened and it no longer associates with it. I have tried both the hostap_pci driver and many different versions of the wlan-ng driver.

Ad-Hoc mode works well (with either hostap_pci or prism2_pci).

This box is running SuSE 8.0.

This is what I am doing:

modprobe hostap_pci
gives this output in /var/log/messages:

iwconfig wlan0 mode managed essid SOLO_1 gives this output in /var/log/messages:

ifup wlan0
gives this output in /var/log/messages:

Aug 28 00:49:21 home kernel: wlan0: TXEXC - fid=0x0137 - status=0x0004 ([Discon]) tx_control=000c

and then hundreds of these:

iwconfig output looks like this:

from my laptop (works, with a Lucent WaveLan PC Card) iwconfig output gives this:

eth1 IEEE 802.11-DS ESSID:"SOLO_1" Nickname:"vaio" Mode:Managed Frequency:2.412GHz Access Point: 00:40:96:48:FD:3F

nwid:0  Rx invalid crypt:0  Rx invalid frag:5          Tx excessive

Again, Ad-Hoc between these two computers works just fine. Would anyone have a clue what I could be doing wrong?

Thanks
Tim
