fugazzz Posted May 26, 2008 Share Posted May 26, 2008 I've gone through a few installs recently, getting my hardware in order and getting an install that I'm happy with. About a week ago I decided to go get a known working NIC and ended up getting a Netgear GA311. I've never been a huge fan of Netgear in the past but that what was available at the store and I didn't feel like waiting for something to get shipped. Anyway...on a couple of the past installs, it seems like the NIC ends up not getting a MAC assigned...just shows as ff:ff:ff:ff:ff:ff:ff:ff I can't for the life of me seem to figure out what I do (aside from reboot) to get it to work again but this last time I noticed just before it started working, I had the cable unplugged from the NIC itself (I had previously disconnected the cable at the router side). Is it my imagination or is there something to the disconnection that is actually making things start working? Anyway, thanks for all the great help!

fugazzz Posted May 26, 2008 Author Share Posted May 26, 2008 Ok, something is wrong for sure. Past few reboots the NIC has worked, but only for a short time. I login, start a file transfer from one system to the other...after a couple hundred MB of xfer, network connectivity just dies. ifconfig and network utility both show no errors/dropped packets, interface is up. dropping en0 and bringing it back up doesn't fix anything. Anyone have any ideas? Link to comment https://www.insanelymac.com/forum/topic/106889-odd-ga311-experience-is-this-normal/#findComment-758808 Share on other sites More sharing options...
agrajag Posted May 26, 2008 Share Posted May 26, 2008 Ok, something is wrong for sure. ...snip... Anyone have any ideas? I would try pulling and re-seating the card to make sure it is not a dodgy connection. Also you could try running at a slower speed (Network in System Preferences, advanced options, set to manual configure) to see if that makes a difference (perhaps you have a borderline bad cable). Failing that, I would bring the card for an exchange- can't see any reason for this to happen on an otherwise good install.

Failing that, I would bring the card for an exchange- can't see any reason for this to happen on an otherwise good install. tried all of the obvious stuff to no avail....one thing I had done much earlier as part of trying to figure out why the system wasn't honoring the mac address of the card was to set that stuff to manual (port speed 100Mb, full duplex) AND had disabled IPv6. I went back and set duplex down to half and enabled IPv6 for auto again and i've not had the network drop out in well over an hour (and it would have done it within minutes previously). I have xferd about 3GB since making that change so one of the two seemed to have done the trick. i'll go back later on and switch IPv6 back off and retest and then try and set the hardware stuff back to auto and retest that as well. It's always been habit for me to set the NICs to 100Full that I never even thought to bother checking those settings...i am however hoping that I can get it to run at 100Full. :S Link to comment https://www.insanelymac.com/forum/topic/106889-odd-ga311-experience-is-this-normal/#findComment-759202 Share on other sites More sharing options...
fugazzz Posted May 26, 2008 Author Share Posted May 26, 2008 Well I may have spoken too soon. I can't say for sure this is a hardware problem now. Here is what happened now. I am running a single VMware Fusion virtual machine of Windows to run a single newsreader application. I had downloaded about 5GB at the point that I started a quickpar verification on a set of files, then copied those files from the VM hard drive back to the Mac (host) through VMware shared folders. During this time, the newsreader was still happily downloading files with great speed. About 5 minutes into the copy, the network dropped out again. Going to boot again and see if i can duplicate the problem.
