3 days later still trying to resolve. 3 different computer operating systems, 3 different email programs same problem and it just started about week ago. Trying to send email and receive error that connection can't be made. Email will sit in outbox and then suddenly it will send. It appears it may be localized to the router since I connect a laptop via cable and it seems to work. Desktop has no problem. Reset router several times, changed channel to no avail. Makes no sense to just start last week. All 3 computers are wireless with different wireless cards. XP SP3, Win 7, and MAC OS. Outlook 2003, Outlook 2007, Entourage. Same intermittent errors. This is driving me nuts! HELP!
