Hello all. I found, why my router (d-link dir-320 b1 aka dir-320 nru) with openwrt has small tx power (lower than on original firmware). When mac80211 (rt2800lib.ko) calculates the gain calibration delta (function rt2880_get_gain_calibration_delta), it gets extremely low value (~ -513). Beacuse of this tx power value reduced by 12 dBm (power_ctrl=2) Is it normal or not? I solved this problem with assigning a power_ctrl value to 3 (+6 dBm) and now tx power almost the same as on original firmware, but I think it is not good solution. TSSI Boundaries from eeprom (offset: 0x6E): 13 EE FF FF 00 00 00 10 02 and step (offset: 0x77): 84. Please help.
