The range is going to vary based on the module type (newer modules have better range). I've read it is recommended to have modules within 30 feet of each other, but that is going to vary based on house / wall construction as well as RF interference. Antenna orientation will also play a factor, so you might try just moving and repositioning the Z-Stick a bit (USB hub can help with this). It might just be in a particularly bad spot or orientation.

I'd recommend trying to get it working in its current location. Adding an IP/USB bridge will just be adding additional complexity IMO and should be avoided unless it is unavoidable.

I believe that is true, but I'm not 100% sure.
