I have a 7520 w/ HS810. It works great everywhere but in my new apartment. There's some kinda interference. If I put the BB within an inch of the HS810, it sounds fine. Anything further, and I get crackling. Interestingly enough, the crackling is the same at 1 ft as it is at 20ft.

I have two Bluetooth keyboards and two Bluetooth mice, and they all work fine. I have 4 PCs and 3 laptops, running on a wireless network, but it's the same network I had at my old apt.


The only things that have changed:

1. Physical location, though I only moved a mile up the road
2. I'm now using DSL instead of cable for internet access
3. I now have a cordless phone (that I've never actually used)
4. I have a very strong wireless signal from another apt in the building (even stronger than my own signal, if that makes any sense)

Anyone have a similar experience that can point me in the right direction?
