10 mbs 100 mbs autodetection

By Marty2001 ·
I have a 10 mbs network with a 10/100mbs network card at the server. My 10 mbs hub just died.
I intend to purchase a 10/100 mbs hub, and want to upgrade my PCs to 10/100 mbs nics in stages.
Will my hub be pulled down to 10mbs if I have 10 mbs and 100 mbs nic clients connecting to it? Is it only some models that this might happen to?
If so, is the best option to buy another 10 mbs hub and put a 10 mbs nic in the server so that I have a hub for the 10mbs PCs and a 10/100 mbs hub (or switch) for the 10/100 PCs.

10 mbs 100 mbs autodetection

You are by far better off getting a 10/100MB *switch*. I don't even know if anyone makes 10/100 hubs, but I rather doubt it and wouldn't buy one if they were available.

The main advantages of getting a switch over a hub (other than the fact that almost all of them now are 10/100 autosensing) are the ability to use full-duplex (if you have one PC per port) and the seperation of each port into its own collision domain.

These two advantages can vastly improve the performance of your network.

Hope that helps.

Thanks for the advice, but it is a little too expensive at present.

10/100 Hubs are very common as well as inexpensive. Plugging a 10T nic into a 10/100 port will only change the state of the current port NOT the entire hub. So that if you have a 100tx one one workstation plugged in next to a 10t connection the onlydifference you will see is a 10 vs 100 indicator on the ports in question. This allows you to gradually upgrade your network structure.
10/100 switches are also coming down in price but at $1300 or so it may still be a bit pricy for you. Some of the better known 10/100 hubs are Linksys or SMC. Most people will recommend 3Com but we have had a number of problems lately with their products and support. SMC has 24/7 and is outstanding in terms of support.

One thing to watch out for particularily with 3Com products is due to some bad (noisy) chips lately they tend to fail auto 10/100 negotiation, we have seen this in both the hubs and nics.
Intel nics are top shelf and we have never had trouble with either smc or linksys 10/100 products.

Good luck

Thanks for the advice - that was really useful - I had headr that some brands were not as goos as others - especially the auto negotiation.
