Can i use 2 smartwi's in 1 house?

Or do they all run the same signal and interfear with eachother?

I have 2 subscription cards and want to split them 2 3 cards each at the same time so total of 6 wireless cards, 3 to 1 master box and 3 to the other

Hi

You can use 2 SmartWi in the same houe without problem.
If you expire interfirence, just reload firmware and chanke the operating freq.
Follow the instruktion in http://beta.smartwi.net/ "SmartWi Toolbox Manual"
