The other day I turned my computer on and my internet wasn't working. I have had this problem in the past, i have a gigabyte GA-MA790FXT-UD5P, it has 2 ports on it, for the past few months one hasn't been working and now neither are, I'm using wireless right now but its kinda slow :/ , one of the times when I had this problem I fixed it by reinstalling Windows (running Windows 7 64-bit) and that worked, but I would rather not do that again, don't want to loose all my music and games. My friend has had the same problem so he just reinstalled windows, there has to be another way to fix this thought right? I have already tried uninstalling the drivers and reinstalling them but that didn't fix the problem. Anyone have any suggestions?

try removing the cmos and placing it back that might just refresh the hardware settings, I tried it a couple of times on some hardware issue

Uninstall the network adapter in Device Manager and restart Windows.

Alternatively or additionally, find a later driver for the network adapter (probably part of a multi function chipset) at Gigabyte site.

Also see if there's a newer BIOS for your motherboard.

I managed to fix it, i reset the cmos and uninstalled the drivers from the device manager and the realtek software and that fixed it, i guess last time all i did was uninstalled the realtek software. thanks for the help guys.

Your not going to believe this... but I had the exact same problem. Internet and PC were working fine the night before and then the next morning nothing. It wouldn't recognize my ethernet connection at all. My wireless was fine so I searched for other people that had my problem. Well I couldnt get anything to work so I thought I'd put in a wireless PCI card. So I shut my PC down and unpluged everything (note I'd already tried unpluging my ehternet cord). Laid my PC out and was about to install my wireless card. But then I saw on the driver software CD to install the software before installing the wireless card... so after a few choice words I plug everything back up and boot up my PC. Well guess what, the ethernet is suddenly recognized again. So for some reason unplugging everything and then setting it back up had some effect on my ethernet card to start back up.

Now a quick disclaimer. I've had a lot of PC problems of late. They're all very random and very wierd. I get BSOD's, freezes. I'm right on the verge of just replacing the darn thing but I'ts a very nice PC and only a few years old so I really hate to take that step. anyways, thats my story.

Is your router or cable/dsl modem running docsis 3.0 or 3.1? if not that is probably your issue. Flip it over its listed on either the bottom or the back depending on the style. Otherwise if you are running 3.0 and above, most routers or newer ethernet cards have diagnostics that will tell you if there are any breaks in the cable.

None of the above? run command prompt in administrator mode. prompt> ping 127.0.0.1. next prompt type: do a combination of ping www.yahoo.com, tracert www.speedguide.net or www.yahoo.com. if you're dropping packets you either have a problem with your provider, or your onboard card is failing. Try a wired ethernet pci card you know that works. ipconfig /all will tell you your dns server. Tracert and ping that. if you have problems then its beyond your box and past the ISP providers equipment. You'll have to call and probably request an escalation to "Tier 2" or a supervisor to get some kid that isn't going to waste your time telling you to unplug and reboot your equipment. If you have an ATT&T wiretell modem, customer service generally is pretty proficient diagnosing problems without the usual BS you get from the other providers.

If swapping to a wired ethernet pci card has the same results, you'll need to download a program to reset your IP protocols to default settings.

Trust me I went through the same garbage. I was running a dlink router and linksys modem both running docsis 1.0+. Why upgrade it works? Well thank you Comcast I had to buy new equipment. I was getting random disconnect but had local LAN connection usually during same hours.

What Ikougar said! I had the same problem after a Microsoft update. All my other devices connected to my modem just fine but my computer wouldn't recognize when the Ethernet cable was plugged in. All I did was simply remove the battery off my motherboard which resets the bios and CMOS to default settings and that did the trick.
