  <p>So the manual provided by Realtek says:</p>
  
  <blockquote>
    <p>If you are running the target kernel, then you should be able to do :</p>
  
  <pre><code>                # make clean modules    (as root or with sudo)
                  # make install
                  # depmod -a
                  # modprobe r8169
  </code></pre>
  </blockquote>
  
  <p>Makefile is:</p>
  
  <pre><code>KFLAG := 2$(shell uname -r | sed -ne 's/^2\.[4]\..*/4/p')x
  
  all: clean modules install
  
  modules:
  ifeq ($(KFLAG),24x)
          $(MAKE) -C src/ -f Makefile_linux24x modules
  else
          $(MAKE) -C src/ modules
  endif
  
  clean:
  ifeq ($(KFLAG),24x)
          $(MAKE) -C src/ -f Makefile_linux24x clean
  else
          $(MAKE) -C src/ clean
  endif
  
  install:
  ifeq ($(KFLAG),24x)
          $(MAKE) -C src/ -f Makefile_linux24x install
  else
          $(MAKE) -C src/ install
  endif
  </code></pre>
  
  <p>Additional info</p>
  
  <pre><code>[root@london r8169-6.023.02]# lsmod | grep r8169
  [root@london r8169-6.023.02]#
  </code></pre>
  
  <p>and directory with <strong>Makefile</strong></p>
  
  <pre><code>[root@london r8169-6.023.02]# ls -lah
