I bought this a few woots ago, replacing my older philips soundbar.
I love it, BUT! Let me address the wireless issue, as I spent COUNTLESS hours researching.
This, like many other wireless devices, works on a 2.4ghz frequency, which is the reason for the drop in wireless connectivity. Here are a list of things you can do to improve that performance, and believe me I tried them ALL:
1 - move your router to a more centralized location in the home
2 - change the channel on your router, try 1 6 or 10, 1 worked the best for me. Oh, and download inssider from metageek.net, it is a freeware app that shows you all routers in your vicinity and their respective channels that are overlapping yours, so you can pick one that does not overlap.
3 - in conjunction with number 2, try the different 'Wireless Id' channels on the soundbar/subwoofer and see which one performs the best.
4 - try moving the subwoofer to different locations.
While these steps WILL help improve the wireless performance, it did not cure the problem for me (I stream movies from a home server to my xbox360, and nothing is more annoying than to have it buffer in the middle of a flick).
The 100% fix is costly, but it will work. Get a dual-band router. I bought this baby:
Then, on the device you need flawless uninteruption (in my case my 360) you can then point to the second band on the router (it transmits both 2.4g and 5.0g bands).
I won't go into the differences in these bands, but if you get into this situation as I did, this is your solution.
