Gigabyte GA-Z77X-UD5H LAN Now not working??

My new system using Gigabyte Motherboard GA-Z77X-UD5H has been working fine up until today, for some reason I now cant get it online?

Under the Device manager it shows the exclamation mark next to "Network Controller" under other devices... I downloaded and reinstalled the lastest drivers from gigabyte for both the motherboards LAN ports (Intel & Atheros) but still no internet connection?

Any suggestions?

  1. are the port led lights on?? and do they blink if you put in a cable?? if no check to see if someone pulling a joke on you and turned the ethernet and wifi off in the bios. a lot of ethernet issues can be due to the eth wire clip can be broken and the wire is falling out or not in all the way on a hard wired port. also try reinstalling the mb chipset drivers. if one of them got damaged the pci bus may not run right.
  2. Did the exclamation mark go away after installing the drivers? If not, then they are not getting installed properly.
