Re: Netflix Poor Video Quality- what to troubleshoot next?

As a test, try changing the DNS on one device (PC or iPhone) to one of Google's or OpenDNS' addresses:

8.8.4.4
8.8.8.8
208.67.222.222
208.67.220.220

Sometimes the default DNS used by ISPs isn't the best when it comes to serving content via CDNs...

The DNS changes didn't make a difference but thank you for suggesting for me to rule this out. As I understand it DNS is just there to resolve a FQDN to an IP address. Once the TCP/IP connection is made between the Netflix content server and my device DNS ceases to be a player. Incidentally, I did some NSLOOKUPS using the Verizon DNS server and the response was virtually instantaneous even with some really obscure domain names.

Like I said, DNS is also used for CDNs to find the nearest server to provide the content; sometimes the ISP DNS doesn't do this well.

I take it you tried this on your PC?
