[QUOTE="silvermac, post: 1621391, member: 337953"] My router is a DrayTek Vigor2130. It does not have a USB 3 port. I have a home lan but it is entirely Ethernet connected and I do not use WiFi normally. The problem for me is with the Bluetooth connection to the wireless keyboard and mouse on the iMac, but that is the same problem as with WiFi generally. (I don't have the problem with another Mac that does not have USB 3, only USB 2. There are a couple of USB 3 external HDDs attached to that computer, but that does not seem to cause interference with its wireless keyboard and mouse. The iMac has some USB 3 devices attached (external HDD, DVD player and sound bar). But even with them removed, the problem persists, presumably because the USB 3 ports are themselves causing interference. I have had a long talk with an Apple techi about it and they are looking into it. But I find it difficult to believe that Apple and USB 3 device manufacturers were unaware of it as it has been known about for more than 2 years.Apple may come and collect the iMac and try and resolve it. But if the problem is as Intel describes, I can't see what they can do about it short of ripping out the USB 3 bus and putting in something that does not kill WiFi. I suppose it might be mitigated by using shielded cables with boots (metal ones) at both ends,rather like certain Ethernet cables. Meanwhile, I shall use a wired keyboard and mouse. But that is not a solution for people who use WiFi for regular communication. As I said, it is an unmitigated disaster for which those who allowed USB 3 to use the same waveband as WiFi and those (including Apple) who implemented it on their machines. regardless are to blame.
