 Hi Alex, 
  
I would filter just on the IP of the server with 
which your communication is. So, first do a nslookup. If you take this approach, 
you give them all that is relevant. 
  
But, the source of the issue is possibly in your 
NAT router. Are you using the same equipment? If not, can you switch back to the 
other equipment to test with?

  Subject: [Wireshark-users] Determine 
  Streaming Problem 
  
  I recently switched to a new ISP 
  and now any video streams that I watch end up buffering.  Both ISP's are 
  resellers of the same network (Bell Canada) and the ISP claims that the speed 
  is the same.  Online speed tests confirm that the speed looks okay, but 
  video streams always buffer now (they very rarely did before) and downloading 
  is much slower.  How can determine the source of the problem using 
  WireShark?  Is there a particular capture+analysis I could run and 
  forward to the ISP to show them that there is a problem (I suspect there might 
  be some throttling going on somewhere since the problem is more noticeable 
  during peak hours).
  Thanks.
