It is an AR2425, but its a Lenovo "ThinkPad" SL500 (based on the IdeaPad stuff it seems :() > I have tried madwifi too (and unfortunaly found out that this driver > isn't any better in regard to transfer speeds) and stability. > > Bob Copeland, recently, wrote patches that make the card set TX power > properly, maybe you need to update kernel to take advantage of that? > > But here on my aspire one ath5k gives 54M speeds, but very often > transfers stall, I will attempt soon to figure out what is wrong. For some reason things seem to have automagically fixed themselves. After a little while it started to connect at 54Mb all by itself, and things are working. Initially it didn't want to work right with any driver, but now it does, at least with ath5k (not sure if its git or from 2.6.29 tbh, I had git installed at one point, but I have absolutely no idea if apt has overwritten it or not by now). > Best regards, > Maxim Levitsky > > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-wireless" > in the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
