That's a good point, but it seems we've never considered this before. This must be a consequence of retrying immediately on lost ACK, but I guess I could see that delaying it for a little bit would make sense. We do delay it if there's no reliable ACK reporting, IIRC, but if we know it failed for sure ... It seems though that if there's some noise or so on the channel you wouldn't be transmitting, so what kind of "network glitches" might affect this? AP going away unexpectedly for some time? johannes
