I tried several times to connect the electric imp blink up but failed. The last led light are green then it change to red(repeats itself). I also trasnfered wifi router near the device so i can use wps button but failed. Before i never encountered this long to connect to blinkup.(estimated 20 times).
So you have blinked an imp before? And previous imp(s) blinked up OK?
I would also try to blink up at someone else’s house, just to rule out router issues.
So blinkup is working if you get a green at the end.
What’s likely happening is that the SSID or password is wrong, OR you are using a US imp and your AP is on a channel that is not in the US channel set (1-11) and so the imp can’t find it.
What channel is your AP on?
