Slow ethernet speed, plz help

[akeros]

Hi,

I'm a brand new switcher and pretty happy about it.

So far, I'm having an issue with the speed of my LAN connection with my XP laptop. The transfer is very slow.

When I use another PC to connect to the laptop, the speed is fine and fast.

I googled for help and tried to manually set the ethernet to 100t/bx thingy and full duplex but not better.

If you already had this issue and can help that'll be great!

Thanks!

Go to Ethernet and in then configure choose Select Manually (Advanced) and try lowering or raising your Maximum Packet Size (MTU). Is yours at 1500? Is this laptop connecting with a wireless or wired connection to your network?

Actually, it was as 1500 by default and I tried to use 1492 the same as my ADSL parameter. But not much help neither.

I'm using a crossed ethernet cable between the mac mini and the xp laptop.

Sometimes the auto-negotiating process goed wrong. Make sure both sides are configured 100Mbit full duplex fixed.
If that is the case and still the connection is slow than try another cable.

Thanks guy.

I tried putting manually both side to 100Mbs and full duplex but not helping.
The cable I use s certified for giga ethernet and with same cable and same laptop I've got fast transfer with another PC...

I'm stuck with transfering big files via usb hard drive, but I'd prefer just putting the mac in the network and copy accross the cable, it is much better I think.

I'll try to google more help

Thanks for your answers!

Cheers

If we got an idea of the configuration of your home network it might shed some light on your issues.

Hi,

You're right I haven't been specific enough, so here is my config:

2 machines:

- Mac mini with OS X Panther
- internal ethernet
- for the moment ethernet config set to auto
- tcp/ip is DHCP with manual IP e.g. 192.168.0.2
- mask is 255.255.255.0
- router automatically set to 192.168.0.1

- Sharp laptop with Win Xp
- internal ethernet
- ethernet set to auto-negotiation
- mask is 255.255.255.0
- tcp/ip with ip is e.g. 192.168.0.1
- win fire wall on ethernet
- removed Qos service

The 2 machines are connected via crossed gigabit ethernet cable. No hub.

I tried:
- manually set both machine to 100basetx and full duplex. Connection is working, I can access to the internet via my ADSL modem connected to my PC. But speed of PC to MAC is 2% of 100Mbps and MAC to PC is 50% of 100Mbps (maybe Mac mini HD speed limit?)
- full automation and negotiation and used assitant on mac. same result as above, slow PC to MAC speed.

Can't think of anything wrong with the PC as I've got a desktop pc with win xp which transfer very fast on both directions (I haven't mesured though)

Hope that gives a better view of my config.

Thanks!

Quick update after more investigation.

I used my backup partition and I am getting at last some decent speed!
But in this configuration, I am not sharing the internet over my private network...

On my main partition where I have speed issue, I am sharing the internet connection so that I can surf on my mac mini through my PC. Now it seems that the Mac is copying files at the speed or through (I can't explain) the internet speed connection!! Which is 2Mbps hence the slow speed. For some reason the Mac is not detecting the 100Mbps speed.

Not a network professionnal so I might be wrong, but it looks as it is my problem here.

If anybody more knowledgeable on networks could help please

Thanks!

Cool, it's all working fie now. I upgraded to 10.3.8 and I used a switch. I can now use 2 PCs and the mac mini in the same network and at full speed.

I guess this topic can be closed now

Hi,

Sorry I didn't see your post earlier.

You seem to have things right. Have you upgraded to 10.3.8 ? That seemed to clear my slow speed issue.

In your case, not sure what is wrong. Have you tried to access the PC via the WORKGROUP path? e.g. smb://YOUR_DOMAIN_NAME;YOUR_PC_NAME/

You should see the shared folders in there.

Have you use the XP network wizzard to help you to setup the PC?
What are your TCP/IP properties on your PC?

Good luck.
