Need info on Network Problem please help.TIA

[ok_interested 0]

Hi there i have a home network setup through my router that was working just fine. the only problem was that the computers on my network had only 10mbs network cards in them ( 3com and SMC ). and sending stuff over a 10 mbs sec network took too long to transfer GB's of data over so i recently put in a 10/100mbs card in each ( both are different intel chip noname cards)

 

now the problem im having is gettin this network to show 100mbs performance . as its now running slower then when the 10mbs cards were in use. before with only the 10mbs cards i could get 1MB/s data transfer between the two computers. now i only get 160 to 600kb/s erratic transfer between the two.

 

note home network, was working fine at maximum capacity of the 10mbs cards now network setup same way only different cards and the network is working even slower then before even though faster cards. so basically how do i get 100mbs performace?

 

here is info on my system:

 

for now just using two computers:

computer 1) win2000pro, 10/100 intel chip card hooked up to SMC barricade broadband router with 10/100 capable cat5e wire.

computer 2) winME 10/100 intel chip card hooked up to same router with same type of wire.

 

network properties:

using tcp/ip protocol on both, and file and printer sharing. no other protocols in use

 

now here is info on stuff im not to clear on how to optimally setup, the following is how its setup now:

 

network card advanced properties tab of the intel 21140card in winME

burst lenght = set to 16dwords

 

connection type = was set to auto sense but thatway the 100 light on the network card did not light up so i set it to 100baseTXfullduplex, i chose tx instead of the other FX or T4 since the name of the driver for the card in the win2k computer says tx and now the 100 light on the network card lights up,, should i choose 100baseFX or 100baseT4 instead? note that when in auto sense the 100 light dosent lightup.

 

extra receive buffers = 64

extra receive packets = 200

interrupt mitigation disabled

memory read multiple disabled

network address not present

process transmit first disabled

receive buffers = 64

store and forward disabled

transmit threshold = 128 bytes

transmit threshold 100M = 512 bytes

Underrun max retries = 2

Underrun threshold = 10

 

the other win2k computer dosent have as many options in the advanced tab.. all it has for connection type is autosense and 10 or 100 normal or duplex but it dosent say TX or FX or T4 like the winME one does. also i tired to keep them using the same in terms of buffers and and threshold.

 

so if anyone has any guide they know of in order to get this running at 100mb/s that would be nice to know, or if anyone can just point out whatever im missing in order to get this running faster, as im stummped and i searched the net with no luck finding any info.

 

if you need any further info just ask.

is there a hub in the picture?

 

Or does the router also act as one?

 

If there is a hub, then, that could cause the slow down if its only rated at 10mbps.

 

What about your cables?

Are they up to spec???

router has built in switch/hub and its 10/100 and cables are 100+ capable. everything up to spec.( here is link to router, incase your still wonderin.. http://www.smc.com/index.cfm?action=products_show_description&productCode=SMC7004ABR )

 

note i have tried in FX and T4 and neither work so its just TX, which is the standard 100 format ( im pretty sure of that )

 

now by puttin it in just 100baseTX alone without duplex it acutally runs better, Downloading from new comp to old, now it starts off at around 6MB/s and quickly falls to 3MB/s which after a few seconds falls to 1.7MB/s or so and stays steady a lil above 1MB/s

 

downloading from old to new it stays around 4MB/S pretty constant

 

there must be some settings that i have to tweak or somthing. im guessing on the winME machine since it looks like the OS is holding it back or somthing. as it starts off at around 6MB/s and quickly slows to just above 1MB/s

 

the above 100baseTX without duplex so far is what is running the best. compared to 100baseTXfullduplex , which wont go above a few hundered kb/s , i find that strange. .

 

any ideas? does anyone know of a good website with tips or info on how some of these network card advanced properties settings should optimally be setup?

 

I checked in sandra on my old comp and its defraged HardDrive can easily handel over 10MB/s that this 100mb/s card maximum is supposed to be. and when its transfering there is little noticeable HD activity, during the download. Although im not expecting 10MB/s i would at least settle for half that.

 

thanks for any help.

Try a switch instead of a hub.

did you follow the link .. looks like you didnt or you would see that the barricade is a all in one highspeed router and switch. there is nothing wrong with the router or my cables. what i need is some OS networking help.

if anyone knows of a good site with this kind of info , or if anyone has any experience with this kinda stuff please let me know. TIA.

What are you using to transfer ? Are you downloading from a local intranet webpage that you set up on the Win2k machine ?? Or are you copying and pasting using the network neighborhood ??

 

Our server runs Windows 2000 Advanced server....and I have noticed differences between copying/pasteing and downloading from our local intranet.

 

Most of the settings in a NIC are not for speed adjustments, other than the 100TX full, 100TX half, Autosense, and so on. So adjusting settings in the Advanced properties of your network card isn't really going to help you much.

 

What are the hardrives in both machines ?? ATA100, ATA66, SCSI, RAID 0, RAID 1....etc.

 

My guess would be to borrow a standard 'decent quality' 100Mb switch from a friend or something....and try that without your SMC router. I have seen a few of these rounter/switch combos that turn a great connection into a sh*tty one. Also, if your 100Mb light is not lighting up in autosense mode, then the card is not reading a 100Mb connection....pretty simple. Sounds to me like its a router/switch problem....

 

Good luck...
