I've posted some photo's of the HH4. http://flic.kr/ps/NmjNq
First impression its very light and if dropped will break so placed it somewhere secure and safe. The feet on the hub are very thin and will snap easily. The unit feels cheap, but looks good (just my view).
Obtaining better coverage than we were with the HH3
So how far can the 5Ghz range reach? In the home hub manager does it show which devices are connected to which frequecncy?
Yes , plus the mac address and ip address which I have left out from the image. The 5gz range is working further than I had expected. Spare room is where hub place and downstairs directly below the spare room 5GHz is working well.
