IX15 cannot discover network even itself after factory reset

Hi Digi,

I faced some problems with my gateway,
Previously I have do some configuration for my gateway, discover network, join network from Xbee Nodes and even try to upload Phyton program from sample.
Then i reset to factory setting on the Gateway iX15.
But i face new problems like the xbee indicator lamp is red color and i cannot discover xbee network.
Thx.

I would suggest looking over Digi IX15 Gateway User Guide
