Re: Mac network [7:58945]
If you're talking about a $100 switch (like a NetGear or LinkSys) can you even set any of the port parameters on that switch? No cheapy NetGear I've seen allows you to do that. If you hook up a Win2K/Linux/etc to this network do you have these same problems?

The switch is non-management the whole network is Mac including the server Doing a packet cap there are a lot of replayed packets this in my experience since it works on a hub is the duplex mismatch.

RE: Mac network [7:58945]
I do not claim to be a mac master here, but unless these are stoneage macs, shoudnt they be 10/100 nics? Most of the cheap switches are indeed unmanaged, so all you can really do is plug stuff in and look at the leds on the front to see if youre getting 10 or 100, as well as half or full duplex. Tried lookin at mac model sites like http://www.apple-history.com/index.html to see what features the models in question have? Tough to justify major expense given the office size, but going managed to a say 2912 is an option??

RE: Mac network [7:58945]
If I recall correctly, G3 beige mini-towers and older hardware all came with 10MB NICs. Without checking Apple's online specs site, I don't know what generation laptops started using 10/100 cards - somewhere in the G3 generation I'd guess.

RE: Mac network [7:58945]
Dwayne, If you can check the network couters on your MAC - look for FCS error. If you have any, then this is a classic duplex mismatch. Second thing you can do is transfer a file to and from the workstation. I use FTP and issue a get and then a put. Comparing the results will reveal a mismatch as well if the transfers are considerably different. It will also indicate which end is having the problem as well - send or recieve. ;) You might have to hard set the speed and duplex on the switch and Mac stations if auto is not working for you.

If it's a Windows server, check out this terrific site for cross-platform networks. http://www.macwindows.com/ For your problem, check out the link in the list on the right regarding cross-platform issues for Mac OS 9. It's labelled Mac OS 9 X-platform issues. There are numerous issues with networking in Mac OS 9.2, unfortunately What evidence do you have that it's a duplex mismatch problem? What stats can you get from the switch? And can you change the setting on the switch? I guess it's a good guess considering that it works with a hub and not a switch, but there are other possible explanations too... There's the infamous problem of the switch nor forwarding traffic quick enough (due to STP) upon startup, so the Mac misses the DHCP response and perhaps AppleTalk replies too. But that would cause an immediate problem, not a slowdown... One thing you can do to fix networking problems on a Macintosh is delete the Apple Share Prep, AppleTalk, File sharing, and TCP/IP files from the Preferences folder. Reboot and let the Mac start over with fresh files. You would need to reconfigure TCP/IP after doing this. Sometimes it helps to zap parameter RAM (PRAM) also. PRAM stores various preferences. You can use a tool called TechToolLite to do this. Wish I could be more help. We haven't run into an duplex mismatch problems on our network of Macs with OS 9.2 and switches. Perhaps a search in Google would help? Priscilla all connected via a switch the problem is that when connected to the switch network transfers to and from the server are very slow i.e. 100meg file take approx 18 minutes Now I have swapped the cheap $100 switch out and replaced it with a another one from the supplier still the same problem I then replaced the switch with a hub and now everything flies along The Mac's are running 9.2 os and from what I can see without doing a network capture there is speed and duplex conflict these settings cant be changed on this os.
