I’m still interested in this topic if anyone has any suggestions.
Would getting a GL-AR300M-Ext and using it with 5dbi antennas rather than the 2dbi antennas it comes with be a good option? Is there any reason that the GL-AR300M-Ext is sold with 2dbi antennas when the GL-AR150-ext comes with a 5dbi antenna?
For my purposes range is the most important criteria (much more important than speed!). Any information about how the different models perform in this area would be very much appreciated.
