I'm seeing something similar with my hardware with recent current.
It associates but I get massive packet loss to my router over the
wireless link:
--- 10.0.2.1 ping statistics ---
425 packets transmitted, 195 packets received, 54.1% packet loss
round-trip min/avg/max/stddev = 1.460/2.894/86.417/8.110 ms
siba_bwn0@pci0:1:0:0: class=0x028000 card=0x1508103c chip=0x431514e4 rev=0x01 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
class = network
cap 01[40] = powerspec 3 supports D0 D1 D2 D3 current D0
cap 09[58] = vendor (length 120)
cap 05[e8] = MSI supports 1 message, 64 bit enabled with 1 message
cap 10[d0] = PCI-Express 1 endpoint max data 128(128) link x1(x1)
Current of May 15 works reliably. I'll try to search for the
offending commit.
