Q In early February, our Comcast service went out, affecting our TV, phone and computer connections for about five minutes. Since then I can’t send e-mails from Windows Live Mail. However, I can still receive e-mails, and have no other Internet connectivity problems. What do you suggest?
Barb Lohmann, Plymouth
A It sounds as if your computer isn’t connected to Comcast’s outgoing e-mail server. This could have been caused by the service outage, some unrelated PC configuration issue or by changes Comcast has made in the way it handles e-mail.
If the service outage disrupted your connection to Comcast’s outgoing e-mail server (called the SMTP, or Simple Mail Transfer Protocol server), you may have to call Comcast’s help desk to get it reconnected.
But try a couple of other things first. Sometimes PC configuration issues, such as your computer having the wrong date and time settings, can interrupt Windows Live Mail. For a list of common configuration problems, see tinyurl.com/a5anlyl.
Another possible source of disruption is security changes Comcast recently made that affect sending e-mail. To comply with these changes, you’ll need to change some PC settings to shift your outgoing e-mail from the PC’s “port 25” to its “port 465.” (These “ports” are software, not physical objects.) See “To configure your Windows Live Mail client” at tinyurl.com/ano2a4z.
Q When my laptop goes to sleep, it loses its connection to my home Wi-Fi network. If I unplug the Wi-Fi router’s electrical cord, then plug it back in, the laptop reconnects again. Any idea how to fix this?
Ann Bodensteiner, Edina
A You can change the settings on your PC so it doesn’t go to sleep. Go to Start, click Control Panel and select “Power Options.” On the following menu, see whether the “balanced” or “power saver” options are checked; next to the one that’s checked, click “change plan settings.” Next to “put the computer to sleep” is a drop-down menu; from the list select “Never,” then click “save changes.”
Q When I typed in the Web address for the Kindle e-reader software that you wrote about, it didn’t work. Why?
Gene Amendola, Riverbank, Calif.
A The “tinyurl” addresses I use in the column only work if they’re typed on the Web address line of your browser. If you instead type them into a search engine, they won’t work.
Why? The tinyurls aren’t real Web page addresses, so search engines can’t find them.
