I had a problem like that once where an ancient OpenBSD (or Solaris?)
router was poorly configured. I was told to turn off window scaling on
the Linux boxes behind it:
sysctl net/ipv4/tcp_window_scaling=0
Eventually, I fixed it properly, by throwing away the broken router.
Not sure if that's just broken PMTUD.
