How much did your connection slow down? It is clear that this commit might possibly slow down your connection, but not by a lot. And that's only because before we were sending with a higher rate than the AP allowed us to... If you need the higher speed then set your AP to G-only to make it include more rates in the basic rate set, that'll speed up your connection properly. That's all discounting driver bugs which may exist, of course. johannes --=-nKeeNjl4BRvdjo5SSGK/ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKFXxnAAoJEODzc/N7+Qma8XMQAIFYa+ZzvbiKdxaicE3tHfIE yHGS6PneVC17txFW13opEAzMUHiF6d3ViwDjYYWiXjfVMOIsqiRcx5NQdSHJHWIy cum2dlh5awrd4jf60G65EEN6PQGU0XFPETdaly8NZzPj98xjcVkrOxJTkpnPeWAl brH18LokWl3U0FuxbXmBUIWXaCLsLovnH1vFaj4fH0+wz317zrLx2dHwp96Mt0WK 4ru1hRJQ0fQyaqKsvi0yeccNitTfCF/3sooC/GoQeNPozK2Pl028zQzjIsaTTmnl qoxr4+mCQ9WxmONEuTIuKKc0WeQzDv/zM61lflN4vMfxnd2QgQYx4Ogj/4Nl7vMU jalOCQH9KQf1CzGlwcPMpOsNg5uz7IlXvjgZW1BDUwiUB4ALycMeVXXy2HblDRBm sDDgacRf/q+Vy0xsMxMgWgfPXFH9K/vkgeMTtC3Q145PBfYk5HIAyQN9BMY1KuuO 5ug3j3YY1U0if6Rm/ttbEIREVZaH38FPbCrLTGkD8+eJgDLvF1cN3Brur+1V7BEb fK6/7JpS7YTLx6JU9lTAkgkhK43pTBJzv82+bHvqITG2EF+807/csMmZj7904RZ6 6ysjIUKB7Pcq3jx+DaMKdMsTkGgyHSAfWAULRxhXQ96Eou5n/0rNaPsA5iOQcGgB jmrNDKczWIb9gpJ5s0Ri =VOWE -----END PGP SIGNATURE----- --=-nKeeNjl4BRvdjo5SSGK/-- -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
