Thread: Network connectivity problems

Hi,

I have Mac OS Lion running on my desktop but i have problems with the NIC. It's a Realtek 8111B chip. I've tried different driver no luck so far. When i'm for example coping files from my client to my server connection is suddenly broken. Can someone assist me to resolve this problem? Thank you.

Motherboard: Gigabyte GA-P35-DS4
Graphics: Nvidia 8600GT
CPU: Q6600
4 Gig memory

It looks like the connection only crashes when i heavily use it (Copying). When i only browse everything is fine. Also when i'm coping files the speed is very different from time to time (60MB - 8MB). If i use AFP or SMB this make no difference for the connection (it crashes).

Are you using:

<key>EthernetBuiltIn</key>
<string>Yes</string>

in org.chameleon.Boot.plist/com.apple.Boot.plist?

And this driver:
RTL81xx OS X Driver [Lnx2Mac's Blog]

Working fine on my GA-P35C-DS3R.

DSDT made with Auto Patcher.

Network >Ethernet > Hardware > Configuration > Automatically

But isn't it a problem with de server?

I'm not familiar with DSDT. Can you explain the above answer? Of course i'll use the chameleon boot loader. I'll used Multibeast to install this.

I downloaded "chameleon wizard" and "ethernet build in" is enabled.

Yes i'll use this driver but when i'm checking "about this mac" i'll see this"

ethernet:

I think it uses the wrong driver (the original driver from Apple)

Network >Ethernet > Hardware > Configuration > Automatically

yes i have these settings

But isn't it a problem with de server?

I think not my Windows client has great coping speed.

Thank you for your time.

Everything looks good
RTL81xx OS X Driver modifies AppleRTL8169Ethernet.kext so you don't see any difference but there are

I can't quarantee that a DSDT is going to solve the problem but you can try.
It's the only difference between our installs. Make a clean install on a empty disk/partition to try.
olarila.com - Lion installation via USB stick using Chameleon
olarila.com - Snow Leopard on Gigabyte Mobos
Make a DSDT with Auto Patcher.
olarila.com - DSDT Auto-Patcher
There's a patch for your motherboard.

Hope you have a spare disk/partition to try
