If that fixes it it suggests that you're hitting a broken firewall/router on the way that doesn't pass on TCP/IP window scaling information and breaks it... OpenBSD didn't used to turn on the options for that in pf by default, and I can't remember them off the top of my head, but I suggest fixing the firewalls and routers rather than patching the problem by disabling window scaling.
