I recently got an Inspiron 7559 and I started to transfer files from my old Inspiron 5447 over Wi-Fi.

Do I need a crossover cable to transfer files from one to the other using a direct Ethernet connection between the two laptops or can I use a standard Ethernet cable?

I assume that by "crossfire" you meant a "crossover" cable. The answer is "no", you don't need a crossover cable. Because your Inspiron 7559 has a gigabit Ethernet port, and nearly all gigabit ports support Auto MDI-X (though not required by standard), a straight-through cable should work.

You will, however, need to manually configure your IP settings for each interface since a DHCP server won't be available on a direct connection.


If you don't have a network switch and want to connect the two computers directly, then yes, you will need a crossover (not crossfire) cable. The individual wires are arranged differently in a crossover cable to enable the signal to "crossover" without a switch, so a regular Ethernet cable will not work.

Edit: @Google Fail raises a good point in his answer; I forgot about Auto-MDIX. You may be fine with a regular cable, after all.

  • I did mean crossover. I'll try it out when i get home. Thanks. Apr 7, 2017 at 18:13
  • It looks like i can connect without having to set up special settings. Turned off the recieving laptop's wifi and connected it via ethernet and its transfering at 60 to 80 mbps. Apr 7, 2017 at 20:46
  • Great, glad it worked for you. Mark Google Fail's answer so others who have this question can see it, and to give them credit!
