This means the Biscotti's Wi-Fi system is being interfered with by something in the area. Items that may cause interference are microwave ovens that are currently in use, 2.4 GHz cordless phones, or other Wi-Fi devices overlapping your channel. Other Wi-Fi networks may interfere with your Biscotti if they are on an overlapping channel. In the 2.4 GHz band, Wi-Fi channel numbers are 1-11 but these channels overlap. Wi-Fi networks in the 2.4GHz band must be separated by 5 channels to not interfere. For example, if you are on channel 1, then channels 2-5 may interfere with you, but channels 6-11 will not. The "good neighbor" policy in the 2.4 GHz band is to operate on channel 1, 6, or 11.
There are free utilities available to scan an area for wireless networks and detect what channel they are on for android devices and laptops. You can use these Wi-Fi analyzers to discover what channels the wireless access points in your area are on and change them on to one that doesn't overlap. As mentioned you want to be separated by 5 channels to avoid interference from another access point so the best channels to be on are 1, 6, and 11.
