[I know this answer may sound a little confusing... there are several versions
of the card so it depends on which version you have... read the whole

may have some hints.... (try setting the pnp setting to off)

is linksys's "official" blurb on the matter....

does the machine have a scsi card? is it assigning the same IRQ to different
devices (like scsi and ethernet even though there are free irqs)?

on a related note, linksys may have a modified tulip driver... which exact
version of the card do you have? The linksys page mentioned above states that
there is a modified driver on "disk2" if you have the wake on lan version of the
card. The following link has links to driver disks... (not all have a linux
driver included since the standard driver should work with them)
