[Mr Skrunts]

Ok,  I know the bare basics to hard ware and am OK at putting a box of bits together and calling it a computer.

I am working with an Abit 32 Bit XP2200+ and a Gidabyte 64Bit D930 based system both with onboard 100MBit Nic's plugged into a ADSL2 modem router.

I seem to be getting 6/10 Mbit transfer speed at best. but this seems to be the best speed I have ever achieved no mater what system combination I have been using.


I have a fair bit of equipment with some of it having 10/100/1000 capabilility.

I have in the past set the netwoks up individually working back from the modem, I havwe even bought the 10/100/1000 Nics and switch/routers  (Netgear I think)

Where am I going wrong and what is the maximum speed I could expaect to achieve.

TIA.  

Any questions/replys from Network Guru's then please keep it simple as you will probably be blinding me with science

What make/model is the modem router? It does have 100M ports I assume?  :-/

Dont actually know, but there is no difference which ever hub I use, even the 24 port 10/100 Netgear hubs that I have.

[Bandit127]

How are you measuring the 6-10 Mbit transfer speed? T'internet?

[TheBoy]

You haven't really described the network kit - is it a switch, or a hub?

Generally with ethernet, expect it to start to flatten at 40% utilisation (better kit will help), so on 100Mb hub, you're looking at 3.5Mbyte/sec

A switch will improve things, assuming its any good, though some layer 3 switches may hinder slightly as they do more processing.

The onboard NIC implementation will drastically affect things - there are good and bad.  Generally, the Intel or Broadcom chips are well thought of, but I seen some rubbish implementations.


Don't bother with gigabit nics unless they are onboard - the pci bus can't handle it.  Even with onboard, ensure that they don't hang off the PCI bus as mobo makers such as Asus do.  Very few consumer mobos implement a better PCI bus than 32bit 33mhz.  PCIe doesn't suffer this restriction - again dependant on how its been implemented.

Currently just a basic ADSL 2 Modem Router, cheapest in the shop at the time as it was an emergency, I believe its an Addon Brand.  5 port jobbie.


All the motherboards I am looking at for the next machine have Gigabit Ethernet (GE) on board, as does my current Gigabyte Board.  I also have a Gigabyte board plus a cheapie MSI board I bought yesterday that both have GE.

I would apprecite a recommendation for say maybe an 8 port Swith/Hub to plug all the above systems into.

Just a real quick check - can you force the Nics on the mobos to 100mbit connection speed only? There used to be a problem with autonegotation of the connection speed 'twixt switches and network ports, so it might be worth forcing the network cards to 100Mbit and rechecking your connection speed.

Erm.. depends what O/S you're running on the machines. Usually, in windows machines -

Right click my computer - manage
Click Device Manager
Expand Network Adapters
Right click your network card, select properties
Advanced tab - find the appropriate entry for connection speed - usually something like 'speed / duplex settings' and set the connection speed to 100Mb or 100Mb FD (for full duplex)

Ahhhhh.  Found it.

Currently set to Full Autonegotiation. I have the option to force Full 100 MBit Full Duplex or Half Duplex.

Will reset it later tonight.  Then give it  good test tomorrow.

I'd recommend 100MB Full Duplex first - there's no real point to setting it to Half Duplex. Good luck with the testing.

Autoneg is now ultra reliable (assuming both ends set to autoneg).

Setting one end to autoneg, and other forced will result in a duplex mismatch, and poor throughput.  Now I don't know the router in question, but I would bet a left gonad that its not a managed hub/switched, and thus cannot be forced

Leave on autoneg

Now that depends 100% on it being a switch - you cannot have a hub running at Full Duplex, only Half.  We haven't ascertained if its a hub or switch.
