I need to use two ethernet ports for a GW like target. Is there an alternative to the RPi, or a way mod the RPi so that it has two ethernet ports?

  • "GW like target" what's that? – Matthew Najmon Jul 7 '18 at 21:06

You could always just use a USB->Ethernet adapter on the Pi.

    Note that the existing Ethernet controller on the Model B is already just an onboard USB->Ethernet chip. – Moshe Katz Jul 25 '14 at 18:30
  • The maximum speed you can get with any protocol or service with an usb ethernet adapter is 5MB/s. I have one at home as a router. – machineaddict Jun 4 '15 at 12:14

Searching using Google I found the Utilite Standard device which has 2x GbE, 2 GB RAM, and a Freescale i.MX6 dual-core Cortex-A9 @1GHz CPU. It's available on Amazon for $159.

    A great device: 2xRJ45-1Gbps, WiFi, Bluetooth, claimed fully working Ubuntu and even an SSD SATA included in the Pro version (Quad-core 1.2GHz). How sad the USB is not 3.0 (as for now, on June 2015): if you are planning to add more RJ45 devices, it makes the difference in speed. – Sopalajo de Arrierez Jun 25 '15 at 21:23

Here are some choices:

  1. Use a USB-Ethernet adapter.
  2. Use an SPI-Ethernet adapter (the same one people use on the Pi Zero). Raspberry Pi people prefer using the one with the ENC28J60 chip on it.
  3. Use both of the above, get three ethernet ports (two above + 1 built-in)
  • So basically you acknowledge that there's no alternative. Nothing in the same price range and spec of a RP. – Benoît Feb 1 '16 at 8:45

    @Benoît Partly. I'm not aware of anything that's on the Pi's price range that has 2 or more ethernet ports. Maybe some Linux-based routers. – Gene Feb 1 '16 at 12:10
  • @Benoît The question does ask, not only for pi alternatives, but also for ways to modify the pi to have a second port. This falls solidly in the latter category. – Matthew Najmon Jul 7 '18 at 21:08

we have developed the EthernetBerry Dual with two ENC28J60 IC.

Best regards Pierpaolo

  • Would you have any speed data for this, perhaps in comparison to this ? – starfry Jun 13 '17 at 20:08
