So as some of you know, I have both a Quad and a DP. The Quad is in the "Loft" and the DP is in my bedroom. There are 3 routers in my house, one in the living room, one in the laundry room, and one in the Loft. The one in the laundry room utilizes the CAT5e jacks around my house and uses those as ethernet jacks. The Quad is connected by ethernet to the network switch, which is connected to the laundry room router via the method above. I have the loft router connected to the switch, so anything on the laundry room network or the upstairs one is accessible. Now, I usually use WiFi on both my DP and DLSD, I get 4 bars originally and then after a bit of use, it fluctuates between 2-3 bars. It may not seem like an issue, but it runs at full speed on 4 bars, but performance is gone on 2-3 bars. I was thinking that this weekend I could use the CAT5e in my room as an ethernet and connect the DP that way. Thus leaving the DLSD, I usually use it in the Loft, but I occasionally bring it in my room and a restricted by the lack of internet. I don't know if this is a range issue or an airport issue. The DP is using and antenna to connect the to loft network and so is the DLSD(using the internal antenna).
