Broken routers not handling TCP window scaling?  Try:
  echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
and see the thread starting at:
  http://lkml.org/lkml/2006/6/13/103

Unfortunately if this is the problem then disabling window scaling is
not really a proper solution; only fixing the broken network devices
works in the long term.
