A common vendor of hotel access control systems (ibahn) seems to be particularly problematic.
I have already experienced that in 3 separate cases the wireless or wired access does not work
with window scaling.

Probably doesn't work with Vista either, unless Microsoft has turned off window scaling in
Vista SP1.

Microsoft went to quite a lot of trouble to auto-detect network routes which fail to work with
window scaling, IPv6 and whatever else, and work around the problems.

Linux relies on the user to set things.  I believe there are some iptables rules you can apply
to selectively disable scaling and ECN.  However, I don't know of any distros with scripts
that detect problems and apply those rules automatically.
