A Little Tech Rant
So, my mom asks me today if it’s possible to extend the range of my existing wireless network in my house so that it reaches my bedroom so my brother can do his homework in there. Sure it’s possible. I just need a repeater (in this case, I was going to use an Airport Express). So first things first. How do I set up the Airport Express to act as a repeater instead of the Selectable Dual Band router it’s designed to be. It’s simple you just set it up as part of a WDS network…… if your base station is another Apple router (e.g. Airport Express, Airport Extreme, Time Capsule). So onto the Google I go. Looking, looking, looking, AHA! I just have to set my router to allow the network to be extended. Great! Time to log into the router admin screen that I have come to know and love and wait…. where’s that setting? Back to Google to find the support for my ancient Linksys WRT300N router (it’s draft-n dammit!) to see if it even supports it. Sure enough it doesn’t. Scratch that plan let’s see about moving the router and the modem to the next floor…… that would prevent me from being able to play XBOX Live so no and I would have to call up the cable company in order to put in a new coaxial jack upstairs. So now I get the pleasure to convince my mom that we need a $190 router for my house, the Airport Extreme. Now I know there are several different dual band routers that are cheaper and don’t have many problems but I’ve been on an Apple spree recently and well the Airport Extreme also gets the highest reviews. Plus should I have an issue with the signal again, all I need is an Airport Express. Problem solved. But now the question is this. After swapping out the router and reconnecting all eight computers, 3 iPhones, iPod Touch, and 2 XBOX 360s back onto the network with all the correct ports forwarded, am I going to have to redo the networked printer I have set up because that will be a bitch. Note to self: Stop messing around with the wireless.
