It seems like OpenBSD added support > for 6205, but I'm not sure if it works for 6250. Worth a try, but I don't think it will make a difference. I had that code once (it should even be visible on the svn history) but removed it because it isn't required, the 6005 series devices work very well without it (I'm using a 6230 (6000g2b) daily) without issues. What is import though is which calibration results are sent to the runtime firmware, I suspect there might be an issue in iwn5000_rx_calib_results() around IWN5000_PHY_CALIB_DC. I remember that someone reported the 6250 devices working once, it might be worth going over the last revisions (there where some calibration related changes) and figure out which one broke it. -- Bernhard
