After you do a complete fresh install of windows 7, if you cannot access internet, it’s most probably that network drivers are removed. you can check for driver status in device manager.if the network driver is missing, you will find a yellow mark next to the ethernet device which mostly is named as “ethernet controller” under other devices or unknown devices.. After the updates a driver cannot be found for my ethernet controller. even worse, i can no longer connect to the internet. even worse, i can no longer connect to the internet. i tried an image restore to a previous version of windows.. Ethernet controller not found / driver cannot be found i had to reformat and reload my system on my dimension 8250 and everything is good except for my ethernet internet connection. the device manager doesn't show the network card at all but there are two unkown devices - a ethernet controller and a pci input device..
Hello . i have an presario cq57-383sq and in device manager, network controller has no driver and i can`t find it and my wi-fi doesn`t work it shows that is disabled from device manager i thins it is because of the network controller driver.. I did some digging, and the ethernet controller is not a device, there is an adapter (probably wireless) that needs a driver. lavalys' program everest will tell you who makes the wireless adapter in your pc. if you can figure out who makes the wireless adapter on your own just install the drivers for it. remember an "ethernet controller" is not a device, it is a general useless description of. Just got a new pc, ethernet controller driver isn’t installed on it and every driver i have tried hasn’t worked. new pc is a custom built pc and is manufactured by asus. windows 7 64bit new pc is a custom built pc and is manufactured by asus..
