Using the Onion Pro as a wifi range extender?
I recently learned how to set up my Onion Omega 2+ as a Wifi range extender. I have it working fairly well, and learned that I can improve the strength/range by adding an external Wifi antenna. However .. this would require that I desolder the 0 ohm resistor on the Onion. Otherwise, I would apparently see no improvement whatsoever, and the added antenna would be 100% useless.
My question is -- can I also use the Onion Pro as a Wifi range extender with an external antenna? And if so, would I also have to desolder the 0 ohm resistor on that device?
@Yvan-Gagnon You just connect a UFL antenna.

@Yvan-Gagnon since the Pro is just 2+ surface mounted on a power dock and it has the same 0 ohm resistor and the same SMT antenna I think the answer is logically YES.
Has anyone here actually tested this to confirm?
As you know @Pavel-Metrokhin is (or maybe he only was
?!) a member of the Onion team / the Omega Squad.
There is a little typo in the tutorial.
The difference between the two is relatively noticeable. Just to remind you, as the value in -dBm gets closer to 0 it becomes more stronger. Since the -dBm scale is logarithmic based, the diference between the two antenna configurations is actually quite large. A difference of -10dBm means that the u.FL antenna has a signal that is 100 times stronger than the SMT antenna at 10 meters away.
A 10 dB increase in level is equivalent to a 10-fold increase in power.
So the u.FL antenna has a signal that is approximately 10 times stronger than the SMT antenna.
dBm means deciBel-milliwatt(s), mW milliWatt(s), uW microWatt(s), nW nanoWatt(s) 0 dBm = 1 mW (1000 microW) power on 50 Ohm impedance -30 dBm = 1 uW (1000 nanoW) -50 dBm = 10 nW -60 dBm = 1.0 nW (1000 picoW) -70 dBm = 0.1 nW -80 dBm = 0.01 nW
So .. yes, then. I would also need to remove the resistor on the Onion Pro, which is unfortunate (I won't be removing it from mine). Still, thanks for your response.
p.s. The article you referenced is specific to the Onion 2 btw .. not the Onion Pro.
