While I'm home for break, I'm using my parents wireless at the house. They use a d-link 802.11g 2.4 ghz wireless router and its hooked up to my their dell desktop. All that is in the office on the first floor on one side of the house. My room is on the other side of the house above the garage and the signal I get with my mid-2008 MBP is extremely sketchy, and hardly reliable. It cuts out all the time. I don't feel like forking over $100 bucks for them to get a new N-router or anything like that, and the other options like range extenders I'm not too familiar with.. I also don't want to buy something that's going to be here, when I'm away at college, other than on breaks and the summertime. BASICALLY, I'm looking at the Airport Express Base station as an investment for myself. Is it a wireless extender? Is it a miniaturized router? Will it help in my situation as listed above^^^ ? And, is it worth it for the price? Can somebody give me a pretty good real world explanation of it please. Any help or input on my situation would be great! Thanks.
