I have noted on two different systems each using a different model router with their broadband connection (one DSL, the other cable modem) that when the wireless computer using the network tries to send out email from Outlook, the messages often won't go out but stay in the Outbox until they close Outlook and restart it. Sometimes the email won't go out even then.
In both of these situations, a second computer is connected to the router by CAT 5 network cable, and those second computers never suffer this problem. Their email in Outlook always goes out. The problem isn't in the setup of Outlook, for the outgoing server addresses are correct, and if the affected computers switch to use a network cable temporarily, they never have this happen. There must be some setting somewhere, either in the router (although I can't find anything that seems like it would affect this), or in the network card settings in XP. Has anyone come across this, and if so, what might I change to avoid this pesky problem?
