You might have a competing wifi channel in your home causing the LCS wifi to conflict with it.
From the manual...
Changing the WiFi Channel In most installations, it will not be necessary to change the LCS WiFi’s channel. However, if you suspect your LCS WiFi is in conflict with another newrby WiFi network, you may improve performance by changing your LCS WiFi’s channel.
To Change the LCS WiFi channel:
1. Hold the WPS button for 2 seconds while in Access Point mode to activate the WiFi Channel selection mode.
2. In channel selection mode, the RED and GREEN LEDs blink the count of the current channel selected (default is channel 1) with a 1 second pause. This sequence repeats twice, and then the channel selection mode is exited.
3. Once you have counted the blinks to determine the current channel, press the WPS button to increment the channel number. Valid channels are 1 to 11, so the maximum blinks observed will be 11. After channel 11 is reached and incremented, the LCS WiFi channel will wrap back to channel 1.
