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

Is there any downside to enabling ECN?

Thanks.

Read this and see if it helps. I do not have ECN enabled and I am not experiencing any issues. It is up to you how you want to configure your box.

This is what I have set for WIN7

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.

Thank you again.
