It seems to me that the Wi-Fi performance of my BOOX M92 is rather pure.
When I "measure" the signal strength using a laptop and a mobile phone, they both show "perfect" signal strength.
In the
"Disassembling of Onyx M92" thread (in a
post by "FDD"), I have found the information where the "internal Wi-Fi antenna" ("ANT1") is located.
It's on the "back side" of the device, about 1 cm up from the "+" volume control button.
I usually hold my device in my left hand, exactly by this left-down corner, so my hand "fully covers" this area.
Even when I'm just 2 meters away from the router, I get 3 bars only (sometimes even 2 -> this seems to depend on the "orientation" of the M92 with respect to the router).
As soon as I move my hand to the top of the device, I sometimes get 4 bars instead of 3 (especially if I hold the device in a way that its "back side" is oriented towards the router).
However, if I move two "concrete walls" away from the router (bathroom, some 6 meters away), the connection breaks (0 bars) or is very pure (1 bar).
What is your experience?
