Episode 1032

Paul from Lake Forest, CA

Paul's dad finally got internet access, but he didn't have a router to protect him against attacks online. So Paul gave him his old router. Everytime he has issues, he calls AT&T and they tell him to disconnect the router, though! Leo advises making sure that the router firmware is updated. Rebooting the router often helps. It could also be an issue with AT&T's internet service.

Buffalo 802.11 AC

Episode 887

Peter from Brooklyn, NY

Since he's using the very new Buffalo 802.11 AC router, hey may be out of luck at this time. He can try using any range extender available, but it may not work with the new A/C wireless spec. Generally, Leo advises getting a Wi-Fi extender from the same manufacturer of the router, and as soon as Buffalo comes out with one for the new A/C spec, that's what he should get.

When I stream video over my DSL internet, why does the quality fluctuate dramatically?

Episode 882

Alan from Simi Valley, CA

This has to do with the speed of the connection he's getting from his internet provider. When the provider quotes a number for speed, they're giving the upper number, or the fastest it could be. DSL, in Leo's experience, is generally more consistent than cable internet, though. Some internet providers have a little trick they use called "burst mode", which means they give real fast internet when first connecting, but then slows down. Leo says he could call AT&T and go a tier higher in internet speed, which would cost around $10 a month more.

What are the benefits of the new Buffalo 802.11AC wireless router?

Episode 877

Charlie from Tampa, FL

The new Buffalo router uses a new wireless spec called 802.11AC, 80 mhz of bandwidth, and is self tuning. It only uses the 5ghz band, not 2.4ghz like most current wifi uses. Because of that, it won't travel through walls as well. This actually might be a good thing though because it will reduce the chances of interference if there's a lot of wifi networks around. The disadvantage of 5ghz is that it might not work for a whole house as well.
