On first glance, that doesn't make any sense to me.  You mean the
router locked up?  It shouldn't care which direction the majority of
the bits are flowing...  Is it possible any large transfer in either
direction kills it?  or was it a one time fluke?  Those cheap little
wireless routers can be flakey...

Nope - as far as the system is concerned a network connection is a
network connection - wireless, wired or carrier pidgin (there's an
RFC) it's all the same to scp

A little ASCII art diagram would likely be helpful here...
