When cold booting my PC I find that I do not connect to the internet. On a restart the issue has resolved itself. On checking Windows Network Diagnostics I get this error message: The Intel(R)82579LM Gigabyte Network Connection adapter is experiencing driver- or hardware related problems. This is a fresh install and installing motherboard drivers once Windows installs something I have done countless times in the past with no problems. Downloaded and installed latest drivers from Gigabyte Sniper M3 site but the issue remains. Suggestions?
Try the latest drivers direct from Intel instead Glenn, probably much newer than the ones on Gigabyte's site. Just select your OS from the drop down box at the top.
It could be that the controller is on its way out, but it wouldn't explain why it only stops working on cold boots. I'm going for a really long shot here, and I'm going to suggest that you update your BIOS if you've not done so already.
BIOS is up to date bar a beta which add little to anything. As it works on a restart then it is only a niggle at the moment but these things can lead to bigger issues. So perhaps a cheap mobo replacement might be in order until such times as I new build. Lack of internet.
Okay, so you are saying you can still see your router (by plugging in its IP address in your browser) and other networked devices, you just cannot access the Internet, right? That means there is nothing wrong with your computer's network configuration (though it could be your firewall - but that seems unlikely since it corrects itself after rebooting), or a setting in your router. When you say cold boot, how long was the computer off? And by cold, do you mean the PSU was turned off by the switch in back or the computer was unplugged from the wall (removing the ATX required +5Vsb standby voltages that would normally keep your NIC alive) or do you just mean the computer/Windows was shutdown?
By cold boot I mean first thing in the morning. When I boot the PC I get a little red x on the little monitor in the notification area. my other PC's (2) boot and connect immediately on boot so it cannot be a router issue. The PSU is not removed from a power source, the power cable is not removed. I only use Windows firewall and have never had this issue.
Advice from Archeum on Overclockers suggested uninstalling the device or network controller and reinstalling. This seems to have worked. Sometimes all it takes is the simplest things to solve an issue.
Beat me to it - this was going to be my next suggestion. However, for greater chances of success, I recommend you disconnect the NIC from your network, uninstall drivers, shut down and unplug the computer from the wall for about 15 seconds or so. This will ensure no power is being applied to your NIC and will hopefully tell your Router nothing is attached to that port. Then connect and boot, then hopefully Windows will detect and configure the NIC properly.
