P.C won.t see lan cable

Hello.
So my pc worked fine since a couple a weeks ago.
When I opened it one day, out of the blue, there was that red X next to the Local Area Connection.
I have a Huawei Hg655b. I thought that maybe the cable is broken, so I replaced it. It didn't work.
Then I opened the P.C. to check the on board network adapter but it looked fine.
I bought a usb network adapter and a wireless stick. Curiously, the wireless stick is working, the network adapter is not. The routher's LAN led's on, the led of the network adapter is on, (sometimes it keeps flashing) but the pc won't connect.
I have been installed the LAN's driver once again and nothing. Try to update the driver, nothing.
I really can't figure it out since the wireless stick is working and the EXTERNAL NETWORK ADAPTOR IS NOT.
Need some help.
Thanks a lot for your time.
