In fact, I connect via a hotel's wifi. So that is the reason. I will try some other form of connection. Many thanks again for your efficient help!

Thanks for the quick reply. The zipped pcap is attached. Hope I chose the right save format. Pierre wscapture1.zip

I have this message (in French) in NOD32 antivirus: ""Les informations de mise à jour ne sont pas cohérentes"", meaning that update informations are inconsistent. Updates are blocked. Sorry, I don't know the English language equivalent of this message. The message cannot be found anywhere on this forum, or anywhere on the net. I am blocked from updating. My license is still valid for two months. Thanks for your help! Pierre
