Driving home on a BT HF call tonight I kept hearing distortion every minute or so thinking that I might have a cell tower issue. This continued for 8 miles and even when I stopped the car in my drive way. I noticed that the problem seemed to disappear after disabling WIFI. My assumption is that with WIFI enabled it scans for a network every so often and interferes with the Bluetooth connection (yes, I know they share bandwidth). I tend to leave the WIFI enabled so it will automatically connect to my home network when I arrive. Does anyone else see an interoperability issue which is driving them to turn off WIFI to avoid BT distortion?
