It was connected last week. It did improve the signal somewhat. I'm not sure if it's the Internet (which we've been having trouble with the ISP) or the unit yet. My daughter has one and it works perfectly; I expect that when I get the ISP squared away, ours will also.
The camera and 18-55mm lens probably exceeded my expectations, but the 75-300mm did not. I expected to get more amgnification from the 300mm end of the lens. I've not experienced any of the difficulties in stabilizing subjects at a distance without a tripod referred to in other reviews. I'm still learning the digital SLR capabilities vs the older digital camera. So my opinion may change when I'm better qualified to use the lens.
