Internet issues
 

Help. I am running on snow leopard 10.6.3 and my internet is not quite stable. My mb is Asus P5N73-CM.

I am using a wired internet connection. The internet disconnects whenever I go to certain websites or run certain programs such as yahoo, hotmail or logon to msn messenger or bittorrent.

When I lose connection, I open up Network Diagnostics and I see Ethernet and Network Settings green, ISP, Internet and Server are red. I cannot even access the router through internet browser. (I tried both connecting to the router and directly to cable modem, results are the same.)

I googled a bit and found that a workaround is to go to Network, turn off Configure IPv4 and apply and then select Using DHCP and apply again. The connections come back on within seconds. However I couldn't find any solution that fix the problem permanently. I also tried deleting library/preferences/systemconfiguration folder and also created a new
Location in network, I still get disconnected.

I have no internet problems when I use a mobile broadband dongles, thus I suspect is a ethernet problem.

Has anyone encountered or heard of the issue? Is there a permanant solution to my problem? Will buying a new ethernet card and installing it work?

What kext are you using for ethernet?

I am using
/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/nvenet.kext
for ethernet.

well that explains why your having problems, you want this kext. To install remove nvenet.kext and install nforcelan.kext reboot and enjoy working ethernet!

Hello. It worked! The thing is previously i tried installing the nForceLan without uninstalling the old kext. =D

Everything is working now. Thank you!!!
