I've recently found a problem with my ethernet, which won't ever connect. Others in my area can connect to it. I discovered this problem when i recently reformatted my computer, about a week ago, and I haven't seen this problem before that. I use my own built computer with an ASUS PCE-AC68 802.11ac Dual-Band Wireless-AC1900 PCI-E Adapter for my 5G wifi, which I haven't seen any problem with. For ethernet we use the Swedish brand Alltele, and many in the area can agree on it being very overloaded at times. When i try to troubleshoot i get the message "Ethernet missing valid IP configuration", and it's seen as an "unidentified network" when i click the ethernet logo in the hotbar. I have tried the following:
Troubleshooted the problem with the Windows troubleshooting function.
Restarted the router and the computer.
Reinstalled TCP/IP settings.
Disabled and reactivated my wifi adapter and my ethernet. (ipconfig /renew and all that)
Checked if there's anything wrong with the cable.
Made sure that my ethernet receives IP adress and DNS server adress automatically.
Uninstalled and reinstalled ethernet drivers.
Disabled fast boot for my computer.
I first discovered the problem after I had installed my new motherboard (MSI Z270 A-PRO) and CPU (Intel i7 7700K). It might just have been a cable I've missed when installing my new processor I just bought, or maybe something isn't compatible with my new setup. A friend thought of the idea that it could be a setting in the BIOS. Other people I've asked said i should set up a static IP address, but there was no information regarding the standard gateway, it said nothing. Any ideas?
