[eepro100] dell inspiron 8000 eepro100 problems

[John Paul Robson]

i'm using 2.4.9 and have had a problem since 2.2
kernels along with all versions of 2.4. i am having a
problem with 2 laptops, both are dell inspiron 8000
that have intel 82557 mini-pci nic in them. i get no
errors from the kernel but i lose most of my
connection after some use. it is very hard to describe
how to reproduce the problem because it happens some
times after a minute of starting up the computer or
sometimes it may take 10 hours to start. what happens
is i lose my ability to connect to anything whether it
be telnet, web browsing, ssh, etc. but i can still
ping sites by ip address. if i am plugged in behind my
router i can ping and connect to other boxes on my
network (i've been browsing through a proxy on one of
them while trying to figure out what the problem is).
i have tried compiling the driver into the kernel and
as a module, i've tried mandrake 7.0, mandrake 8.0,
and now redhat 7.1 and still have the same problem. i
have also tried replacing the router and cable. when
the problem starts i've tried unloading the module and
bringing the network back up and still no luck. i've
tried plugging the computer straight into the cable
modem and it doesn't work and tried unplugging a
computer that is working and plugging it into this one
and it will not work. i've tried using static ip's and
dhcp. i've also tried forcing the nic to 10mbps and
100mbps. i've tried with it forced to half-duplex and
full duplex. the only thing that fixes the problem is
by rebooting the computer and immediatly works again.
i have talked to a few other people on the dell linux
laptop group and they are having this same problem
(not all of them).

any ideas?

p.s. i tried with intel's own e100 module and i get
the same problem - maybe it is just the hardware?
