Review: works as advertised but you might want a W5500 instead - works as advertised but you might want a W5500 instead
Review: Make sure the pins are completely in! - Works just fine so far. ***WARNING*** Make sure that the I/O pins set inside completely. You have to put some pretty firm pressure on it. I was debugging for hours trying to figure out why it wasnt working but it was just because the pins were sitting in all the way.... Hope this helps

## Questions & Answers

**Q: What's the purpose of the smd near the reset button?  it's not present on the official arduino version.**
A: Hello,The product I received was of such poor construction (bent and uneven pin lengths, excess solder blobs and flux, overall low quality) I didn't even try to use it. I purchased another one at Radio Shack made by SeedStudios, and it worked. The SMD is most likely a EEPROM if I had to guess. Sorry I cannot provide more information. Since that time I have moved on to Teensy 3.1 and LC's (ARM) and use a Wiznet module I purchased from Mouser for IP based connectivity. If you need more horsepower I recommend https://www.pjrc.com/teensy/teensy31.html , great forums and better product.

**Q: Will this ethernet shield work with the Arduino Due?**
A: I don't know, but I can't imagine why it wouldn't. The pin configuration is the same as an arduino r3 for all the pins that are important to the shield. However, if you are planning to use the lcd board, it has problems with the Ethernet shield.

**Q: Can this shield connect to your home network wirelessly, or do you need to plug in an ethernet cable to the board?**
A: No, it's an Ethernet sheild. You need to plug it in to an Ethernet socket. They make wireless shields though. They will have antennas. Sometimes you can get two different frequency bands for better range it requires multiple antennas.

**Q: is this compatable with arduino uno Rev 3?**
A: I have it on a Sainsmart UNO R3 clone and it is working well. So yes, it should.

### ⭐⭐⭐⭐ I should have known better... ...but I'm a slow learner
*by D***S on January 1, 2017*

Pins 8 & 9 and pins 10 & 11 were connected with excess solder. This inhibited communications between the Arduino and the W5100 shield. It also heated up both components but not to failure - yet. It works OK after removing the solder overflow. ** UPDATE 1/18/2017 ** The first one I purchased had solder issues that cost me a lot of time looking for software problems. Who would think to check the board with a magnifying glass? Not me. I needed two more boards and I decided that I can do 10 minutes with a soldering iron to save $20. Sure enough, one board was OK except for solder smears on some of the pins. Cost me 15 seconds to fix that. I was surprised to find that 8 pins on the second board had not been soldered at all. There went another 45 seconds. Both boards tested just fine with an Arduino program that has a web server, an email sending routine and reads & writes to a 16gb flash drive on the W5100 shield. If you have a magnifying glass, a soldering iron and don't like to spend more money than necessary, this is a pretty good deal. So I'm upping my rating from two stars to four stars for those with some soldering ability. All others should look elsewhere.
