Hi,
I've successfully installed the HostAp driver with a D-Link DWL-650/DWL-500 configuration, running Kernel 2.4.19.
Setting the card in Managed mode everything works great and I get a fairly high link quality:
iwconfig wlan0 gives:
Warning : Device wlan0 has been compiled with version 13 of Wireless Extension, while we are using version 12. Some things may be broken...
wlan0 IEEE 802.11-DS ESSID:"default"

Link Quality:80/92 Signal level:-53 dBm Noise level:-100 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:212 Invalid misc:15864 Missed beacon:0
When setting the card in Master mode, i.e.
iwconfig wlan0 mode Master essid test
and checking the link quality with iwspy, I get:
wlan0 Statistics collected:
00:02:2D:23:FE:49 : Quality:19/92 Signal level:-77 dBm Noise level:-98 dBm
typical/average : Quality:0 Signal level:0 Noise level:0
As you can see the link quality is very low. Checking my the link quality on the other end (a windows machine) confirms the results.
iwconfig at this stage gives:
wlan0 IEEE 802.11-DS ESSID:"test"
Mode:Master Frequency:2.422GHz Access Point: 00:05:5D:5B:BA:8A

The Bit Rate is now 2Mb/s instead of 11Mb/s.....changing Tx-Power has no effect.... Any ideas?
