They will back off to up to 2 minutes. This is correct behaviour according
to the specs.

There is a wireless extension someone has been playing with called SNOOP.
I dont have the paper handy, but the idea is basically to snoop on the
node before the radio hop to avoid long paths back when frames are lost
on an unreliable radio end node.
TCP itself doesnt do well above 10% packet loss and gets nasty above 30%.
This is mainly because it doesn't have any way to tell congestion from
other forms of loss. A radio link with 20%+ loss should be using a local
reliable transfer scheme or some kind of FEC such as golay or viterbi
encoding.
