I have a R40 - 2722-3YU

I haven't experienced this problem. If it only happens with a key or a couple of keys, then the "switches" for those keys may be bad - you may have to change the keyboard. If it happens for every key, then something it's something else.

There is a keyboard config area in KDE where you can specify if the keyboard should repeat or not. Though I don't know exactly what they mean, you can also specify "sticky keys", "slow keys", and "bounce keys".

On a loosely related topic, what does it mean if the caps-lock light keeps on blinking?

For some reason they have problems talking to each other. It'd be interesting to know if the low rate is due to packets lost/retransmission, or because the protocols are reducing the rate.
