So I just bought the airport express (2012) couple hours ago, I hooked it up and not happy with it. The wireless range is same as my Linksys e2000. I only use "G" on my linksys. I even tried wireless "N" 5Ghz on the AP express and the range is same as my Linksys wireless "G". Am i doing something wrong? both of the routers are in the same location. also there was a lag in the audio when i stream audio to my surround sound using optical. I played 720P video on my imac(2011) the audio did not sync up with the video. especially if i jump to different parts of the movie/video. Also no 5.1 audio to my surround sound, only 2.0. I was able to get the 5.1 surround hooking up to the imac directly and not lag in audio. I was disappointed with the AP express. Now I have a couple of questions, I am considering return the AP express for the APTV 3rd gen. 1) if were to get the APTV and i mirror play to my HDTV with HDMI and audio using the OPTICAL to my surround sound, will there be video/audio lag from a large MKV files (~4-6 GB.). I read somewhere that APTV does not support MKV but there is an app called "beamer" that can make it work. 2) will I get 5.1 surround sound from MKV files that have 5.1 audio? 3) are ANY way I can extend my Linksys e2000 wireless range with my Express? Mostly ill keep it if I can extend it. BTW, don't mistake me hating on Apple products, I love them. but the Express disappoint me. Maybe ill but the newest Extreme when I have more money, hopefully it will be better than express.
