JD has a FIOS connection, but his computer keeps auto joining his neighbor's Wi-Fi. Leo says it auto joins because JD probably joined it once manually. JD should go into the Wi-Fi settings > Network preferences, highlight the connections, select Wi-Fi, and then under "Advanced", select "forget". He can also order the connections according to his preferences.
Isaac says that Epson has a scanning feature in it's AirPrint App which would enable people to scan images via WiFi.
Brad says that getting an inverter in the truck, and then plug in a regular Epson printer and you can print via WiFi. All you need to do is turn on the hotspot or just add wifi and you can't print directly. What about scanning via WiFi? Leo says that scanning to Evernote is a great option and you can do it through your phone. In fact, there's a huge amount of apps on the iPhone that you can use your camera as a scanner and then upload it in PDF format. JotNot Scanner Pro is one.
Charlie wants to know what Powerline Networking is and why would anyone need it? Leo says the idea is that the house is already wired with power lines, so why not piggy back on them? When it first came out, it wasn't that great. Engineers have improved it to the point that it's very reliable and is great for those who have large houses and need to access their network throughout the house when Wi-Fi isn't practical.
Chris is a long haul trucker who surfs for free Wi-Fi wherever he can find it. Is there a system that will help him find WiFi signals? Leo says not really. Wi-Fi is really designed for a range of about 300 feet. That's why the 3G/4G access is so sophisticated. It has to do with handing off from one area to another.
John wants to secure his wireless network, and is wondering if he should set it up with MAC addresses. Leo says MAC addresses don't really do anything. He recommends setting up the router with WPA2 (NOT WEP) encryption and give it a good password with alpha and numeric digits. He should also set the SSID for something that is easy to remember (Leo uses dead rock stars).
Ronnie has a PS3 and an XBox connected via a switch to the TV via a Trendnet Ethernet Bridge. Leo says that the PS3 has WiFi built in, which means switching isn't really necessary. But Ronnie says his WiFi switcher works better with multiple devices, but it keeps losing it's configuration. Leo says that assigning static addresses is an option, but it's dangerous to do that from a security standpoint. The chatroom says that using a third party bridge router is probably the issue. It's best to use the same brand when dealing with WiFi bridges.
Corina wants to get a mobile device that she can stream video to watch. How much bandwidth should she get for a 3G tablet? Leo says that 8GB is usually fine, but if she's going to stream video from it, it's better to stream via WiFi and not 3G. Video takes up a lot bandwidth and she can burn through 1GB an hour watching it. Most portable devices have a memory for WiFi that it's near, and will automatically join a hotspot.
Leo says that mobile devices remember WiFi networks, but he can go into the settings and disable the option to join a network automatically. That's what causes it to remember them. Leo also recommends using the Windows WiFi tool and not the one that came with his computer. It should be under the 'Network and Sharing Center'.
David has heard about ClearBand wireless internet called OMGFast for $29.99 a month for 50MBPS. Leo says it's essentially WiMax and suggests going to BroadbandReports.com to find out what others think and get reviews. Users are reporting a constant 45-55mbps down, 4mbps up consistently. Latency isn't great for real time gaming or VOIP.
