They do not play well together. I recently ditched my DSL and went cable internet connection. Only one in my area is Cox, and I got a motorolla modem from them. Then I started seeing the box randomly disconnect and reset. Well after numerous calls, and 3 tech visits to the house I got some answer. On the way out the door talking to the technician it came up that I had an iPhone. He told me that over some time period they had been getting verbal reports and trouble calls relating to iphone and that motorolla modem. Something about interference. So last 3 days I have left the iphone away from the modem and sure enough, no drops at all. Anyone else out there had similar problems? I have encountered one other person that had a similar problem with their itouch.
