As mentioned in the mailing list, the problem is that the atheros driver takes a long time to associate with 11b access points, but associates immediately with 11g access points. I recently upgrade from the 6.0 kernel (a clean install) and had had no problem with that kernel. The card associates quickly with both 11b and 11g access points in Windows. My card is a D-Link DWL-G650. I used the following command to initialize the card: > ifconfig ath0 ssid 126RNet channel 11 mode 11b After waiting until the state is "associated," I proceed with DHCP as normal and everything works fine. I have tried the ath_rate_sample, ath_rate_amrr, and ath_rate_onoe kernel modules; all have the same problem. I have read src/UPDATING and do not see an update listed. The computer I'm running it on is an HP ZV5000 (aka Compaq R3000); the atheros is attached via cardbus. Thank you for your help. >How-To-Repeat: Use an atheros card to connect to an 11b access point. >Fix: No direct fix known, but I suspect the patch will be simple, perhaps a driver rollback. I am willing to work with developers if they can give me a list of files devoted to the atheros driver. >Release-Note: >Audit-Trail: >Unformatted:
