My suspicion is focused on the Ubuntu desktop because of the coincidence that the problem started with a major upgrade. Yes. We have the following on the network ... not all at the same time. * Qwest modem, outside the firewall. * Netgear wired/802.11g wireless router. No evident problems with wireless connections. * Ubuntu 9.10 on Dell hardware. Wired connection. (Main suspect) Thinking about putting in a new Ethernet card since I have it "in stock" anyway and it's doing me no good in the box. * Apple notebook. Wired connection. ** Windows Vista. Have seen some symptoms. ** OS X. mild symptoms. * Apple notebook. Wireless. No known symptoms. * Apple iMac. Wireless No known symptoms. * (Occasional) HP netbook running Ubuntu 9.10 netbook remix. Wireless. No known symptoms. --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
