I've been having some odd problems. When I do iwconfig, I get this:
wlan0 IEEE 802.11b ESSID:"IceCube"
Mode:Managed Frequency:2.412 GHz Access Point: 00:11:24:02:28:6F
Bit Rate:48 Mb/s Sensitivity=-200 dBm
RTS thr:2346 B Fragment thr:2346 B
Link Quality:98/100 Signal level:-56 dBm Noise level:-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:912296 Invalid misc:1734189 Missed beacon:0
But my card is an 802.11g card, it's the DWL-G510 using the Marvell chipset, the driver being mrv8ka51 and obtained from the ndiswrapper website ( and not the ones on the CD ).
I often get a rating of 54Mb/s but the throughput I get seems to be along the lines of an 802.11b connection whereas with my laptop, I get much higher transfer speeds.
I'm running Gentoo with the 2.6.9 Gentoo Kernel with ndiswrapper 0.12-r3.
Thanks in advance.
