I am going to try to put this together as well as I can but at this point my brain is fried from trying to sort this out. I wiped my computer and reinstalled windows 7 with the disk that came with it, and now my internet won't work at all!

Jan 4, 2015 - Download UnknownDeviceIdentifierand post the log it Creates in. @system32 drivers pci.sys,#512;Ethernet Controller [UNKNOWN DEVICE].

First I tried hardwiring it, tried 2 ethernet cables, neither worked, both times it said that there is no connection available or something to that effect. When I try troubleshooting, it just says 'Windows did not detect a properly installed network adapter. If you have a network adapter, you will need to re-install the driver.' I have no idea what to do because I don't have any sort of disc for this, and I haven't had to do this before. In the past if I tried hardwiring the internet it would just immediately work, without me needing to download or update anything.? So then I tried to install my wireless adapter, and no matter which USB port I have the dongle inserted into, I get this error: 'Insert the wireless USB adapter into your computer.

Click OK to continue.' I will click okay, it will pop up again. I will switch it to a different USB port, and it will pop up again a few seconds later. When I first installed it over a year ago that never happened. It worked really quickly no problems. But now no matter what I do it will NOT work and it's driving me crazy because I have no clue what else to do.

The internet was completely fine earlier today, but after I reinstalled the OS it just will not let me connect to the internet in any way whatsoever. Edited by baffledwtf, 05 January 2015 - 04:10 PM. Hey guys, I actually ended up getting the wireless adapter to work, turns out for some reason now only 2 of my USB ports are working.

I'm pretty confused. The computer was built by my ex boyfriend, I'm not sure if he messed something up or what, the USB ports have been cutting in and out randomly for quite some time now, probably about a year or so.

I'm trying to fix the 'ethernet controller' not working wondering if that could help but cannot figure out which network adapter is in the computer, as it says 'not available'. I'll post some pics. Let me know any additional information you need. I don't get why I would be having so many problems! Karta cvetov muline dmc kupitj. Oh sorry I missed that last message, I will do that. I do already know that there are issues popping up in the device manager the ethernet controller if that's what you're looking for (sorry I'm not 100% sure what to look for) says: manufacturer: unknown the drivers for this device are not installed. (code 28) driver provider: unknown driver date: not available driver version: not available he got all the parts off of newegg, I know the motherboard is a gigabyte but I'm unsure of the model, how do i find that out?
