my network manager shows connection through wifi, but my network manager shows connection through ethernet.

wlp5s0 is your wireless device ID regardless if the output of ifconfig prints "Link encap:Ethernet". If your computer was wired to an ethernet port your connected device ID would start with an em or p.

Look at the output of the command
ip addr show
or
ifconfig -a

By the way the ifconfig command is depreceated, use ip instead. The output of the ifconfig -a should of printed a listing for your wired ethernet port assuming it is enabled. Did you post the entire output?

I used ifconfig -a, and my ethernet card is no where to be found.... needless to say, it has a cable connected to it

Post the output of the command:

lspci | grep Ethernet

If the network adapter is not enabled, recognized or the module is not loading it will not be displayed in the output of the config display. Are you sure your actually connected via wired and not wireless?

Could be a driver problem. Post the output of the command:
lsmod | grep r8101

I did not see that you edited post 5. It is possible that you have a hardware problem.

I've never seen this... I've always seen a case where, hardware either gets detected by the OS or not... but this intermittent stuff... never!
