Exactly my point: this laptop's transmitted packets are received just fine on the other end, it's the replies that are getting missed by the decoder so the chipset is not too badly broken, apparently. Unfortunately, I am not really a DSP expert, so there might be deeper reasons why the soundmodem is using a specific sample rate rather than the one most convenient to the hardware, especially considering that quite a few recent chipsets only offer a limited selection of rates.
