Intel Pro 100/VE Intermittently Doesn't Work

[djm88]

Hi Guys,

 

Just having a few problems with my LAN connection on my work laptop. As you can see from lspci, the card shows up. I have performed the modification on the AppleIntel8255x.kext\Contents\Info.plist with the device ID 0x10928086 added to the end.

My problem seems to be that en0 works sometimes and at other times it doesn't. When it doesn't work I have to reboot because I do a sudo ifconfig en0 down and it returns this:

 

daniel-mihaleffs-presario-v6000-gg178paabg-a-k:~ dan$ sudo ifconfig en0 down
Password:
ifconfig: interface en0 does not exist
daniel-mihaleffs-presario-v6000-gg178paabg-a-k:~ dan$ sudo ifconfig en0 up
ifconfig: interface en0 does not exist

 

Just wondering if anyone has any ideas of how I could possibly fix this?

 

Anyone's help/ideas would be greatly appreciated.

 

Thanks

Don't know whether this helps but I found this when I performed a sudo dmesg when the LAN connection doesn't work.
