I also now see that some articles say I should use b43 and others b43-legacy as I have rev 3 of the card. Very very confusing and certainly not what I was hoping of Ubuntu 's new release. Thanks for giving me a point in (hopefully) the right direction. Cheers Dave

In fact, the ssb driver looks at the PHY revision of your card, and loads the correct driver. If you had a BCM4306 rev 2, the it would need b43legacy. I know that is correct as I'm the one who converted bcm43xx into b43legacy! Did you build the kernel you are running, or are you using the one that Ubuntu built? If the latter, I understand why the appropriate debugging options have not been set. I have been trying to get Ubuntu to set the debugging options for a long time, but the idiots don't seem to get the word! If you built your own keernel, then you need to run 'make xconfig' and select the debugging options. Larry

Please run the command sudo cat $(find /sys -name ssb_sprom) and send me that long string of hex digits that follow. Thanks, Larry

So just seen your message. The cmd gives: 014000001300371720430080020002000010001800000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0F007466A59AFFFFFFFFFFFFFFFFFFFFFFFFFFFF4510A01277FBACFEFFFFFFFF3C000000000000003E000D00FFFF00000000000000000194 I feel we are now in the land of voodoo. FYI I'm not a computer pro just an amateur willing to learn and who hates giving up. Thanks once again for your support. Dave |
