You have K2_0_7_... firmware. It works 100% without removing the resistor. We use MC8790, MC8792V and lots of other manufacturers with RB411U and RB411UAHR.
Already has couple of RB411 with mc8790 and it works just fine. But this one with mc8790v got mentioned problem. And yes - firmware is K2_0_7... etc
Can anyone told me - what is this resistor for - i can remove it with ease, but to get it back - it should be a problem )
One more stupid question...did you attach the antenna?
Antenna - wat is it ? o_0
