I'm having disconnect issues with my newly acquired Mini and brand new Roamio Plus. The Mini works fine for a while, but then starts stuttering and at times throws up the network disconnect issue. I have a cat 5 cable running between two GigE switches. On the office switch is an ASUS router/wifi, cable modem, various office equipment and the Mini. The Livingroom has the aforementioned GigE switch which has the Roamio, a wifi access point, sling box, Roku 3 and Roku Soundbridge. The cable between the two switches runs through walls, and has my own homemade ends, which I can't totally vouch for, but haven't given me problems till now. Last night I measured throughput between two computers with GigE NICs. First I did it with the desktop and laptop in the office off the same switch, got a benchmark of about 800 Mbps. Then I took the laptop out to the livingroom and ran the same test and got about 400Mbps. Given that this is way higher than the bandwidth needed for moving HDTV, I'm not sure where I stand. As a further test, I replaced the cable embedded in my walls with a known good cat 5 cable running between the two switches. I'm still having the same issues.
