It's the job of the 802.11 L2 to hide correctable packet loss L3 so most radio link loss isn't passed on to TCP. This could just as well read "the wifi L2 error correction doesn't try hard enough".

This problem is very common but it wants fixing on the L2 and not TCP. Turning up the FEC on the L2 would reduce its capacity even further though since more of the bandwidth is taken up by the FEC (and so does this TCP level FEC).

3G gets it wrong on the other extreme, it pretends to always have 0% packet loss, your packets just sometimes show up 30-100 seconds late and in order.
