It's been a long known issue with some WiFi cards (not just the RTL cards) that some manufacturers don't connect both antennae on some models of portables, so you should update your configuration accordingly (on Linux), or use the driver supplied by the machine manufacturer (with the correct config) rather than downloading the driver from the RTL website.
