network stalls transferring large files (especially over samba)
 

i posted this before in the mandrake forum, but i recently switched the box to slackware and i'm still having the same problem. i'm using a linksys lne100tx (off the top of my head) with the tulip driver. when i transfer large files, the transfer rate will drop to nearly nothing after copying a few megs. not only this, but my ping drops, which affects everything using my network interface. the only way to fix the problem is to cancel the transfer and restart my eth0 interface:

ifconfig eth0 down
ifconfig eth0 up
dhcpcd

any ideas?

Can you post the output of
lspci -v;
I need to know exactly what type of NIC you have. The above statement should give me that.

i'm assuming you only need the NIC junk:

00:06.0 Ethernet controller: Linksys Network Everywhere Fast Ethernet 10/100 model NC100 (rev 11)
Subsystem: Linksys: Unknown device 0574
Flags: bus master, medium devsel, latency 64, IRQ 11
I/O ports at ea00 [size=256]
Memory at edfdfc00 (32-bit, non-prefetchable) [size=1K]
Expansion ROM at edfa0000 [disabled] [size=128K]
Capabilities: [c0] Power Management version 2

I haven't been able to find anything as far as problems with Linksys Network Everywhere Fast Ethernet NIC. How does the error count look on
ifconfig;
?

ifconfig has 0 errors listed. i think i might have seen errors before, although no great amount (<100). if i ping another computer on the lan after the nic has stalled, at the end of the ping command it will say for example:

7 packets transmitted, 0 received, +6 errors, 100% packet loss

but ifconfig still won't show any errors. the problem seems to be worse the more stuff i have running. if i'm in runlevel 3 with the gui, i might be able to transfer a 50 meg file. if i'm in runlevel 3 cli, i might be able to transfer 100 megs. if i'm in runlevel 1 with the nic up, i might be able to transfer 200 megs.

i checked linux drivers from linksys to see if i could find something more specific to my hardware instead of tulip, but it looks like tulip is the standard driver for my card.

i'm beginning to think it's some sort of strange hardware problem. i have just started having video problems as well--sometimes when i maximize a window or move the scroll bar in a window the screen will completely turn one color (most of the time white, sometimes other stuff like blue or pink) and i can't fix it except by restarting. the computer seems to still be running, but i can't see anything. even if i CTRL+ALT+F1/F2/whatever i still can't see anything, although i can tell the system is switching to the command line terminal.
