I tried to add some new lights to my WXM but it looked like the module was too far away as it wasn't recognizing it. So I unplugged the WXM and moved it closer to the lights. Several WXMs showed up on the apex so I deleted all the units, restarted the apex and plugged the module in after it booted up. A single WXM was listed so I went to update the unit's RF chip (as per instructions) then updated the unit. When updating the firmware it states will start in 10 seconds but never does anything. When I checked the unit the solid orange light is now flashing orange. I've tried plugging it in different places and rebooting the apex but it no longer shows up in the apex anymore either. Any ideas how to fix this issue?

Thanks!
