I don't know what happened but all of the sudden (about two days ago) my wifi is absolutely horrible. I asked my coworker if it's working fine for him and he says it's fine. I used Ookla's speed test and get a ping of about 8ms but it doesn't even finish the test. It times out. I get internet here and there but nothing close to even allowing me to use Facebook and Facebook chat. Here's some information for you.

eth0      no wireless extensions.

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"My Network"  
      Mode:Managed  Frequency:2.437 GHz  Access Point: 06:27:22:F1:4F:B9   
      Bit Rate=72.2 Mb/s   Tx-Power=20 dBm   
      Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
      Encryption key:off
      Power Management:off

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0    
      Tx excessive retries:0  Invalid misc:113   Missed beacon:0

docker0   no wireless extensions.

So I tried to get around the wifi issue and plug in an ethernet cord, but it doesn't even detect the ethernet cord. Here's some more info.

Some revisions of Realtek NICs do not work well with the standard kernel driver.

So press Ctrl+Alt+T to go to a terminal and type:

sudo apt-get install r8168-dkms

That should solve it!
