Yeah my unit being a transceiver can be a problem for them. I think I won't take the risk because I paid 300$ for it and I don't want to lose it
I don't think you did anything wrong with your setup but it is just a general rule in wireless networks, and it applies to radiowaves probably: You can have the best quality cable, there will always be some loss. But for sure if you get a more powerful antenna, it will improve the signal.
