There was a similar post about the ScreenLogic not being able to connect through the OPs home network, and it was due to the ScreenLogic having a default gateway (network address) setting of 192.168.1.1 For some reason the ScreenLogic reset itself to its default settings. Many home networks use 192.168.0.1 so the fix was to go into the home router settings and change it to use 192.186.1.1 (which will then break all your other network devices connections) however then once the ScreenLogic was connected you could then change the gateway address in ScreenLogic settings back to use the homes gateway of 192.168.0.1.

Why does the Configuration program say “Looking for Controller”?
If the Configuration program displays “Looking for controller,” for longer then 60 seconds when you startIntelliTouch ScreenLogic2, this may indicate a communication problem somewhere in the system. If ScreenLogic2has been previously working without a problem, try the following steps to resolve the problem:
1. Make sure your wireless ScreenLogic2 device is connected to your wireless router. In most cases, theeasiest way to re-establish a connection is to perform a cold boot of the ScreenLogic2 device:
a. Wireless Tablet – Press the Suspend button located on the left-side of the Tablet for approximately 4seconds. The Tablet reboot process will take approximately 20 seconds.
b. If step 1 does not fix this issue, go to step 2.
2. Locate your ScreenLogic2 Protocol Adapter and wireless router. Verify the wireless router Power LEDin on. These two devices should be located near one another. Cycle the power to both of these devices.You can use a paper clip to reset the Protocol Adapter by pressing the recessed reset button. You canunplug and plug back in the wireless router to reset it.
3. Verify the wiring to the protocol adapter and IntelliTouch Load Center.
