I recently try arduino ethernet shield. When I do the project with router in my class, it worked well. I can ping it and I can read my sensor from the computer client.
But when I try to do the same when I get home, my ethernet can't connect to router in my home. The lan port indicator where the ethernet plugged is turn off. I try to open the example DhcpAddressPrinter, but it didn't work (it was work in my class). I try to connect to different port, but the result is same.
My lan ports are in the good condition, because it work well in other devices.
Is ethernet shield work only for certain router? Or is there configuration that need to be done to make ethernet shield connect with router? I have try to google it but I still get stuck.
Router in my home is TP-LINK model TL-MR3420. I power arduino from usb laptop.
I appreaciate all of help, it means a lot for me.
Pardon my bad english.
