> There is several places where bbp17 is changed. > > Editing the code looking for calls to the function rum_bbp_write, I've been able to find where bbp17 is changed at init. Changing rum_def_bbp[3] (which is reg 17) to values quite 'big' like 0x10 or 0x14 doesn't seem to affect its behaviour. Lowering it even more (0x01for example) sometimes shows more reacheable AP's in range; but signal quality still very bad. Changing RT2573_NOISE_FLOOR doesn't make any change (in terms of signal quality, which remains the same). Any idea if is there anything to change/tune ?
