Hi Sander, > So i'm wondering is there a hardware limitation of stations that can connect to > this mini-pci card in ap-mode ?

I'm not exactly sure why we put -EINVAL rather than -ENOSPC or something like that, but this is a limitation. > If it is a hardware limitation, are there any other intel mini-pci adapters that > don't have this hardware limitation (or at least a highter one). With the newer 7260/7265 adapters you might be able to go up to 14 or 15 stations (I haven't checked exactly), but that's not a significant increase - the fundamental limit of 16 station entries is still there and at least one is needed for internal tracking for multi-/broadcast transmit transmit (and another one might be reserved for P2P on those devices, and I might be forgetting another one perhaps which would mean 13 is the max) I don't believe that the driver (or even firmware) would be able to work around this. johannes -- 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
