Hello I need some advice, I have some small home LAN network(Win2000pro) with two comp. with 3com 3c095-tx cards with cross-over- IBM shielded cable 1,5m. In standard operations I have about 5-6 mb/s and in copy with Total Commander I have 7-8 Mb/s.
In one machine I have Intel 815e mb with 933e coppermine, second machine is Asus p4p800/ p4 2.4c(integrated 3com GB card disabled).both comps in ata 100, udma, both with HDD's 7200/8mb.

In my firm I have similar computers with LAN of two in cross over but I have speed about 10-11mb/s

I tried 3com drivers for 3c905 4.31 and 4.41. I get same speed with both. I tried several crossover cables from different manufactures and its same.
Do you have some suggestions what to do, maybe some of setting in network advance could boost speed, ( just to mentioned I am in 100mbit/full dup. on both computers), maybe some of these which are defaults could change speed:
DoubleNego-disable
Down poll rate-8
Enh Lan Power Mgmt -off
Flow Control-Enable ( I really need this option on Enable, when its disabled and when I play DVD's from network I could get choke's and some times skippings)
InitDelayCount-0
LnkChk-disable
PhyCompat-enable
RWU ARP-disable
RWU Magic PKT-Enable
RWU Ping-disable
Rx Checksum Offload-Enable
Software Cable detect-Off
Stdby Rwu Magic Pkt-Enable
Stdby Rwu Pattern-Enable
Tx Checksum Offload-Enable


If you have some idea please c'mon share it with me, if you know some good LAN booster software or some other LAN speed optimizer please share it with me.
do you think that I need to put some switch or router(some advance with 24 or 32mb) to boost speed, I really need 10-11mb/s if its possible
Thank you.

Good to see that APK is a high quality producing member of these forums

In regards to performance increases

Do the NICs share IRQs?
Have you tried pinning the link speeds and duplexing?
I do agree with APK and his TCPIP stack tuning.


The 3c905 series came in three flavors IIRC. If they are revision A, then they are only 10 meg cards. Revisions B n C encorporated WOL as well as a Bel chipset.

And just to ramble on a little more funny how you commented on how flow control improves your DVD viewing. When in actuality, more packets are being sent to "pause and start" your DVD stream. Gotta love not dropping all them packets.

I got 8 or 9 3Com "3c905c", every card has wake on LAN and boot rom,
4 are made in USA, 2 in Ireland and rest in Singapore.

Model is 3C905C-tx-m.

Sorry, Had to remove the pic for obvious reasons.


If you are trying to watch DVD's over a LAN the common usage is to reencode the movie to the data rate most appropriate to your network. It's been a long time since I've done such a thing but if you really don't feel like reencoding your movies then simply buy some Gig nics and some Cat 5E cable and your good too go. Cost shouldn't be a factor 'cause Cat5E is cheap and so are Gig Nics. Gigabit switches are also pretty cheap now too.

LOL nice man ..... Easy on the P2P stuff.

Other solutions include USB and Firewire pc to pc connections. Certainly more bandwidth than cat5e

Dosfreak also brough up cat6 and gig-e. Another viable solution.

Oh you mean "names of files", of course I forget about that, my bad m8y,
I could put pic without real file names, because picture present this boost in the right manners.
