the title might be a little confusing, but basically here's my setup: - 4 lines from the dish come into a wb68 (eventually this will go away) - 4 outputs from the wb68 go to a swm8 - comcast to off-air on swm8 - swm1 to hr20 - swm2 to hr23 my home network is motorola docsis 3.0 modem going to wrt54gl (w/ dd-wrt), with one port from router going to a linksys srt224 switch. the rest of my network is wired into that switch...both receivers are wired using ethernet, i do not have deca. here's where the odd thing comes in...the hr20 is on the network all the time, and the light on the switch for that port always seems to be lit. the hr23, however, while it seems to always be on the network (whole home dvr always works from both locations and on demand works fine), but the link light on my switch only comes on when i access whole home or on demand on the hr23. most of the rest of the time, the link light is off. is there a difference as to how the hr20 and hr23 access the internet/network? a few other notes: when i came home from work this afternoon, the link light for the hr20 was on and hr23 was off, just as usual. both boxes were turned off all day. i turned on the hr23 and accessed a recording from the hr20, and the link light for the hr23 came on. i have turned the hr23 off now, but the link light stayed on (i'm sure it will go off at some point). i haven't tried accessing whole home on the hr20 while the hr23's link light is off, but i haven't ever tried to access it where it didn't work.
