I had a problem with explorer slowing down, defender not opening and general slowness. I figured it was a virus so I shut reset windows and kept my files. When I got everything installed I updated the bios. Sometime after I noticed I was able to connect wifi (which I'm using now) but not the LAN cable. I went to acer and updated the driver but it said the hardware was not found. I looked in device manager and Ethernet card is not listed. checked on hidden devices and got this list but I don't see the "Realtek PCIe GBE Family Controller" listed anymore. At this point my noob skills are maxed and I'm not sure what to do to fix this. My wifi at work and home are terrible so the LAM line is a big reason I got this model. Thanks for your assistance!
