Howdy all,

My Mac OS X is running fine, I've got currently everything working and all the kexts I needed are installed, however. My internet connection is pretty slow. Software Updates are taking years, Its not going higher then 2 KB/S.

My ethernet device:

02:0f.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ [10ec:8139] (rev 10)

Is there a tweak or hack needed to resume my internet speed on Mac OS X?

Thanks.

Sorry. Forgotten to patch my kext.

For people with the same issue, please follow this:

Download this file

Open terminal:

sudo su
rm -R /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleRTL8139Ethernet.kext

cp -R <path to>/PCGenRTL8139Ethernet.kext /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/

chown -R root:wheel /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/PCGenRTL8139Ethernet.kext

chmod -R 755 /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/PCGenRTL8139Ethernet.kext

touch /System/Library/Extensions

shutdown -r now

Thanks.

My friend you are my hero. When I began my search it became obvious I needed the PCGen kext, however it was not clear where it went or even how I was going to get it.
This post was a one-stop-shop to get my dl speeds from 1-4k and pings from 59-3000ms (pinging local router) to 350k and 0.72ms
Bless you
Now back to searching to fix the USB issues!
