Card is badged "Edimax EW-7108PCG" but the .INF file indicates that it
is a Ralink Technology Corp RT2500 series Wireless LAN Card.
Platform is Dell Latitute CPx H500GT.
OS is Mandrake 10.0 download edition, uname -r says 2.6.3-7mdk
I've renamed the ndiswrapper.ko.gz file (which came with mdk) to
something else, checked modprobe.conf, and commented out a line in
modules.conf 'alias ra0 rt2500' (inserted by Ralink's driver install
script which I tried earlier, unsuccessfully).
I compiled and installed ndiswrapper as per the INSTALL file, and tried
to get it to work. The system would always hang up sooner or later,
sometimes after doing various iwconfig operations and bringing the link
up & down etc. When it has remained un-hungup for a while iwconfig did
seem to indicate that the card is talking to the aether - getting s/n
readings in db rather than x/y figures etc.
I've now recompiled with make DEBUG=1 .
I did 'modprobe ndiswrapper' and then 'dmesg' and got the following:
ndiswrapper version 0.8 loaded
ndiswrapper adding RT2500.sys
PCI: Enabling device 0000:02:00.0 (0000 -> 0002)
PCI: setting latency timer of device 0000:02:00.0 to 64
wlan0: ndiswrapper ethernet device 00:50:fc:d8:b8:f9 using driver rt2500.sys
spurious 8259A interrupt: IRQ7.
After a few seconds the system hangs up (with DEBUG=1 it now hangs up
quite repeatably :-|)
The Tx/Rx and Link LEDs come on solidly on on card, then a second or so
later the system stops reposnding to mouse and keyboard input, and ther
is no change in the clock on the taskbar.
It reminds me rather of the symptom of having a wired network card set
to an interrupt used by some other device in the system (back in the
days of IBM PCs, XTs and ATs, DOS 3.x and PC-NFS :-). That would lock
the system up as soon as a packet came in which caused the network card
to generate an interrupt request.
 Ralink's driver is for 2.6.3-4mdk instead of -7, and to compile from
their source requires modversions.h which Mandrake doesn't have.
 just that - should I also have done ndiswrapper -i <module name> too?
