jmorlan Hmm... That's funny. Premium,MVM join:2001-02-05 Pacifica, CA kudos:4	ECN I noticed that ECN is disabled by default in WIN7. I checked to see that my router is ECN capable using this tool from Microsoft and then enabled it via netsh interface tcp set global ecncapability=enabled Is there any downside to enabling ECN? Thanks.

Thanks. That tool says it's for Windows XP and Windows Vista. No mention of Windows 7? You are correct. However I think it works on Win7. In any event it correctly identified ENC capability on my router. And it turns out there is a downside. Some web-sites don't work with it. I just spent all day troubleshooting a particular site that opened for one machine on my network but not another. Turns out enabling ENC on that machine caused the site to fail. Thanks for reminding me that I had tweaked this setting. It solved a nagging problem. See: »RESOLVED Same site. One computer can connect, the other .... Thank you again.
