I am running all cat6 and have a netgear prosafe GS105 5 port switch.
I am running 2 laptops and a desktop which all have gigbit, and all have similar read/write speed to the N299. I cannot use netgear NIC's. Nor should I need to as all my existing setup runs very well together.
The N4100+ also has a more powerful CPU.
You should be getting more than 400Kbps /sec for sure.
I would think that it's defective. One way to know for sure is to use a crossover cable and directly connect the nas box to one of the laptops. If the speed doesn't improve I'd return it.
I went through some of this when I thought I would get better write performance for my 4100+ I soon realized no matter who I chose to use, none of them could do any better
