I RECENTLY RESET MY AIRSIGHT CAMERA, AND NOW I CANT CONNECT TO THE CAMERA WITHOUT A CAT5 CABLE. I SCANNED NETWORK, CHOSE MY SSID, PUT IN PASSWORD, AND THAN UNPLUGGED IT WHILE IT'S REBOOTING, BUT IT FALLS OFF THE NETWORK AND WONT COME BACK ON UNTIL I PLUG IT BACK INTO ROUTER. I HAD IT CONFIGURED BEFORE THE RESET AND IT WORKED FINE. I EVEN TRIED WAITING A FEW MINUTES AFTER THE REBOOT TO UNPLUG, AND STILL NOTHING
After reading your post, i tried doing what you did, unplugging my CAT5/POE CABLE, and to my surprise, it acted like yours.. could not connect wirelessly, but could as soon as i plugged the CAT5 back.
So, this is what i did....
I cleared my router ( Factory reset ) which screwed that up so i had to reset ( use the CD ) to start over.
Before i started... i unplugged the CAT/POE cable from the camera..don't for get the power if you re just using a CAT5 CABLE and Power Plug. Unplug the power from the camera too.
I rebooted my computer then restored my router to the original settings.
Then plugged up only the power back to the camera ( left CAT5 unplugged) and ran the IP Camera tool which instantly brought up the IP address before the screw up BUT
It is now working wirelessly as i type this.
FYI.
Before the unplugging CAT5, i had set my camera - Obtain IP from DHCP Server
I then, unchecked the box Obtain IP from DHCP Server
Reboot computer and alls well that ends well... so far.
