If this is not the best place, can someone please point me to a very good networking site. The problem I am having seems very bizarre to me. I haven't been able to find anything of this nature searching online, I've tried every tweak I am aware of, and I've had the AT&T technician out here. He did seem very knowledgeable and was at a loss, too. However, after many days and untold hours on this I finally found what is at least an indication of the problem.
I have U-verse at 12 Mbps on Win7 and a Realtek PCIe GBE Family Controller. The problem is most noticeable on my music site (radiotunes.com, formerly sky.fm). Most of time it works perfectly well. However there are times when it starts cutting in & out or stops altogether. By watching Active Connections I found that when it cuts out the port assignment is being changed, and when it stops completely port reassignment has ceased (ports are not exhausted).
Now for the really bizarre part. This only happens at certain times of the day when one would expect network traffic to be heavier. Btw, U-verse is VDSL and not the standard DSL so traffic should not be a problem. Furthermore, radiotunes is a European site so I wouldn't expect it to be a site overload problem when it's 6:00 pm PST.
What it seems like to me is that something in Windows does not like what it is receiving on the music port during the busier times of the day and misinterprets that as needing to reassign the port. Beyond that, I have no idea what it is or what to do about it.
P.S. - I've tried turning off Comodo, doing malware scans, speed tests, using different browsers, and doing all the other standard things I can think of that one would normally do.
Erratic port switching
Why would the DNS servers do a new name resolution ? I haven't used radiotunes, but it seems possible that they would stream from different places that would require some type of name resolution. You can change to Google's DNS servers (8.8.8.8 and 8.8.4.4) to test that theory, though.
It is also possible that the website you're streaming from gets overloaded at peak times.

When I switched my alternate with my primary it stopped happening. I wouldn't expect it to start so early on a normal Sunday, but still, I want to see what happens later today and after 5:00 on a weekday. If the Comodo alternate DNS has a problem I was going to test it further by going back AT&T's DNS servers.
"Why would the DNS servers do a new name resolution ?"
I was wondering about that, too. I thought about the Comodo DNS servers being the problem when I noticed a pile of queries adding up in my connections and recognized it as my DNS server address. I suspect that making repeated requests thru so many ports to an unresponsive server, the streaming stops, and Windows or Flash or Opera or something decides to re-establish the connection which will cause another port to open up and a new request to the DNS server for name resolution.
As for the streaming site being overloaded, like I said I wouldn't expect that at 6:00 here when it's pretty much the middle of the night in Europe, although I hadn't completely ruled it out.

Therein lies your problem. Why have a firewall handle dns? That's much slower than have the dns handled by the modem-router. If use comodo to set dns servers then all Web traffic gets redirected via comodo, which has too many dependancies, e.g. Windows software, comodo software, drivers, etc. Just use the dns hard coded into the modem-router and let comodo filter all the other stuff.I was wondering about that, too.
