I've been trying the new combined patch (combined_2.6.20.2.patch)
posted by Larry Finger on Sun March 11.
This is a 4318 card:
----------------------------------------------------------------------
kernel: bcm43xx: Chip ID 0x4318, rev 0x2
kernel: bcm43xx: Number of cores: 4
kernel: bcm43xx: Core 0: ID 0x800, rev 0xd, vendor 0x4243
kernel: bcm43xx: Core 1: ID 0x812, rev 0x9, vendor 0x4243
kernel: bcm43xx: Core 2: ID 0x804, rev 0xc, vendor 0x4243
kernel: bcm43xx: Core 3: ID 0x80d, rev 0x7, vendor 0x4243
kernel: bcm43xx: PHY connected
kernel: bcm43xx: Detected PHY: Analog: 3, Type 2, Revision 7
kernel: bcm43xx: Detected Radio: ID: 8205017f (Manuf: 17f Ver: 2050 Rev: 8)
----------------------------------------------------------------------
Assocation seems to be about as reliable as before (best when in the
same room as the access point, which is a LinkSys WRT54GL).
iwconfig reveals:
wlang IEEE 802.11b/g ESSID:"branci40" Nickname:"Broadcom 4318"
Mode:Managed Frequency=2.437 GHz Access Point: 00:14:BF:BA:77:03
Bit Rate=54 Mb/s Tx-Power=19 dBm
RTS thr:off Fragment thr:off
Encryption key:off
Link Quality=68/100 Signal level=-46 dBm Noise level=-73 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Using iperf on the internal network (iperf -c 192.168.1.100 -r), I get
these speeds (averaged over 4 tries for each rate):
6M: 16.4 Mbits/sec
9M: 16.9 Mbits/sec
(11M: 13.8 Mbits/sec)
12M: 17.5 Mbits/sec
18M: 17.6 Mbits/sec
24M: 18.0 Mbits/sec
36M: 18.2 Mbits/sec
48M: 18.2 Mbits/sec
54M: 18.2 Mbits/sec
By comparison, an Orinoco Gold card in exactly the same encironment:
wlan1 IEEE 802.11b ESSID:"branci40" Nickname:"HERMES I"
Mode:Managed Frequency:2.437 GHz Access Point: 00:14:BF:BA:77:03
Bit Rate:11 Mb/s Sensitivity:1/3
Retry limit:4 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=58/92 Signal level=-27 dBm Noise level=-85 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:16
Tx excessive retries:3 Invalid misc:0 Missed beacon:0
yields speeds in the range between 4.9 and 5.07 MBits/sec under iperf.
Using wget to get a large file from a distant host, I get download
speeds in the range of 590--615 KB/sec (i.e. about 1min 30secs to
download the bzipped tarball of the kernel source).
Thanks once more,
Jim
