Your Tech Questions Answered, Part 3 In this batch of questions, I answer questions about setting up wireless audio, remotely accessing a parent's computer, choosing a streaming-video option, stabilizing a Wi-Fi connection and picking a good computer for a schoolkid. You can also read my answers to the first and second batch of questions. I would like to add wireless speakers to my home audio system. I currently have a wired system with a receiver connected to my Airport Express, and I can play material from my laptop wirelessly. I would like to add wireless speakers that can also talk to the Airport Express. What do I need in order to set this up? You'll need some powered speakers (ones that don't require an amp, also referred to as "PC speakers") and another Airport Express for the pair. Then add that Express to your network, and you'll be all set. I would like to know how I can remotely access my mother's computer. I'm going to get into this in a later column, but start here: logmein.com, gotomypc.com and splashtop.com. I'm trying to decide between Apple TV or a Samsung's Smart Blu-Ray player that supposedly has a Web browser. What's your opinion? I haven't checked out Samsung's latest offerings, so maybe it's great. I do know that full Web browsing on a TV can be a pain without a keyboard, though. This is not an endorsement, but I have an Apple TV in my house and have been happily using it for at least a year. My DVD player was unpacked when we moved in two years ago, but I've never plugged it in. My access point suddenly stops working, interrupting my Wi-Fi, and then starts working again a few minutes later. This happens a few times a day. Do you know of any reason why? There could be several reasons, but I refer you to an earlier question and suggest you see what channel your router is operating on and whether it's crowded. Moving to a less-used channel may make your signal more stable. What's a good family computer solution for kids heading into middle school? Schools are Mac, home is one PC laptop. The kids mostly need online access to Web-posted materials, with a fairly routine need to type up documents for printing at home or saving to the school server, via VPN. I'm looking for a system to transition into middle school next year, as well as for another middle-schooler two years later. Is a tablet with keyboard extension a good bridge? Maybe with a desktop or laptop in a few years? Right now a Mac laptop seems like overkill given the relatively light use, but a tablet alone is not sufficient for typing papers. And portability is good, since the kids travel between two parents" homes, library, friends" homes for projects, etc. Could you be a little more specific about what your needs are? Just kidding. This is great. I like tablets as home-based devices to consume content, but for doing actual "work," I think a laptop is superior. You're right about a Mac laptop - it's a fair amount of coin to drop on middle-schoolers (not that your or my children shouldn't have the best of everything, of course, but I'm not rich enough for that). So I'd get them a cheap Windows-based laptop. Which one? Oh, something less than $500, probably from HP or Dell. Maybe this HP model, the Pavilion g6, which costs around $400. Since what they'll be doing is primarily Web-based, you don't need a lot of horsepower, but an iPad isn't really well-suited to this, and will ultimately cost you more.
