Sadly, no. With your tree, the 4311 generates a spectrum that looks like my 4306 - the amplitude saturates the detector, but there is a high-frequency spread that goes at least to channel 5. The iperf rates are as follows: Rate set Transfer rate (t/r) 1 Mbs 0.85/2.84 2 Mbs 1.64/3.02 5.5 Mbs 3.84/1.55 It failed with the lowest of the OFDM rates (6 Mbs). I didn't try any higher rates. These tests were done with the standard power. Larry _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
