I'm lucky to have a network drop located behind my entertainment center, but I suspect that's a bit rare. Fortunately, the MP115 supports 802.11 b/g wireless capabilities as well as wired. This allows you to put the device where you need it, without regard to network cables. To try this out, I disconnected my network cable and cycled the power on the box. When the box came up, it scanned for wireless access points. In my case, it found three (Figure 7).

I selected my access point and the MP115 brought up a configuration screen. My access point is configured using 128 bit WEP encryption, so I used the remote keypad to enter the key cell-phone style. It was a bit awkward, but it shouldn't be a daily experience. I did notice that the box would forget my wireless settings when switching back and forth from wired to wireless, so in my case, at least while I was testing, it was a common experience. Note that the device does not support the more secure WPA encryption, which is a serious omission.
My access point is in a bad location for best range, being located in my basement furnace room because that is where cable comes into the house. My entertainment center, where I used the device normally, is directly above the furnace room, so there was a wood floor between test AP and the MP115, but only about 6-7 feet of distance.
With this setup, I was able to watch a couple of full-length movies ripped from my DVD library over the wireless link without problems. At one point, I was even watching one while transferring another over the wireless link and I saw no glitches or artifacts!
For a range test, I moved the MP115 to a spot about 30 feet or so away, but with a floor and a couple of sheetrock walls between it and the basement AP. Note that the furnace room also has a lot of metal ductwork that was probably blocking and bouncing the wireless signals around.
In this location, I found that sound would stutter, and finally stop and quit to the selection menu. I also sometimes found menus to be non-responsive, as if no content could be fetched from the server. I tried a DVD-quality movie, which started to play, but then stopped and locked the box solid, requiring a power cycle.
In all, I judge the range of the MP115 to be comparable to other wireless devices I use in my house. It worked where I needed it, but had problems in locations in the remote corners of my house where I usually have signal loss. So if you want to run wirelessly, choose your location carefully. By the way, it would have been nice to have a detailed signal strength display during this testing or as an aid in determining AP / MP115 placement. The only signal strength display is in the initial access point selection menu (Figure 7) that only had rough signal quality settings.
