Slow Network Help!

[Tavish Muldoon]

Hello,

I have 2 computers networked together. A W2k with SP3 and a W98SE
machine. They are both using Ethernet
and are hooked together via a UB Networks Geostax/E-Micro16 Hub.

I am transferring some files from the W98SE machine to the W2k
machine. It is a 900 meg file and it is taking
18 minutes to copy across.

They share a DSL connection and internet access seems to be fine.

1) How can I dianose where the problems is

2) What network monitoring software is out there I can use?

3) Suggestions on how to speed this up?


Thank,

Tmuld.

Look at the status lights on the hub. Do they say you're
connected at 100 Mbps? Or only 10?

Try some smaller files -- in the 5 to 10 Mb range -- and check your
throughput. This looks to be a candidate for simple POE.

Hmmm. 900 MByte * 8bits/byte = 7200000000 bits
18 minutes * 60 sec/min = 1080 seconds
Rate = 72000000000/1080 = 6.7 MBits/second
This is about the expected throughput of a 10-Base-T connection.

I'm not sure you have a problem.

3) Suggestions on how to speed this up?

Switch to a 100-Base-T network.
Make sure both your NICs support 100-Base-T speeds
Make sure your Hub supports 100-Base-T
Make sure your cable runs aren't too long.
Sometimes a 10/100-Base-T NIC will auto-select the wrong speed. Go to
the control panel or Device Manager of both machines and force the
speed of the NIC to 100-Base-T (Half-Duplex if using a Hub).

HTH,
John

Hello John,

Thanks so much for the help!

I check the network cards on both machines - both SiS 900 PCI fast
Ethernet cards according to device manager.

Both NICs (on W98SE and W2k are on auto config, but have options for:

100Base TX
100Base TX Full_duplex
10BaseT
10BaseT Full_duplex
Auto_config

Both are set to Auto_config.

The Geostax/E-Micro16 has 4 lights on the front:
Pwr: ON (green)
Act: Flashes (green)
Col: OFF (sometimes flashes yellow)
MEP: OFF (no idea what this is)

Ont he far right there is a dial with 2 options - UPLINK MDI and
MDI-X. It is set to MDI.

Hope that info helps. I am not sure what I should have the settings
at.

There is a PPPoE adapter on each machine - software for the DSL
connection.

Would you be able to suggest a network monitoring tool?

Do you have any other suggestions?

All - thanks so much for the help!

Tmuld.

From what I can find, the Geostax is a 10-Base-T hub. In general, if
it doesn't have 10/100 speed LED indicators on it, it probably won't
handle 100-Base-T.

You need to trade your hub in for a hub (preferably a switch) that will
support 100-Base-T.

Both are set to Auto_config.

Sounds like it decided to use 10MBit/Sec.

Try setting both to ..
