Could be a broadcast storm coming from the HR20. Sometimes faulty software and/or hardware can blast all FF broadcast packets onto a lan, or if you may have created a bridge / switch loop as there is no TTL in layer 2. When a broadcast packet is sent out all computers on that network must process the packet payload, this consumes CPU resources. Think of it as someone constantly tapping you on the shoulder while you are trying to get work done, that is what your computer can be going through under a bc storm. Broadcasts are normal and necessary it is how computers find each other for the first time on a network.jahgreen said:

But your problems quacks and waddles so it is likely a duck.
