I recently bought 2 linknode R4's from Amazon. However after powering up either Linknodes I cannot detect their wireless AP's. I bought a AdaFruit usb ttl cable to try and reload a test program from the Wiki page and the orignal program from git, however nothing seems to work and i'm not sure if i'm doing it right. I would be grateful to any ideas people have. I tried to contact Linksprite support but i have heard nothing back. \it is such a pity the support is so bad as i was really looking forward to experimenting with these boards.

Hi are you sure you never detected these wifi AP? if you ever connected wifi and this wifi still exists, R4 will not send wifi AP again. if your two linknode R4 can't work, how about change a different environment without wifi and see if they can send wifi AP again.
