Hi Bob, With only 768 kbps you might have a problem. The sling codecs are not very bandwidth optimized like flash let's say or others, on the other hand Sling have a very bad habit to eat the entire bandwidth. 768kbps is a marginal speed for sling, the image will be OK but you won't see details. On the other hand based on my experience bandwidth fluctuates (kind of networking QSB :-)) and sling is adjusting codecs accordingly, is very tolerand in bandwidth variations (you start getting an image from 3-400Kbps but low rez) of course the immage quality is adjusted accordingly. Maybe your providers from Hawaii to State of WA are more consistent but in my case the bandwidth from Europe to Canada is constantly qsb-ing from 1000 to 1500kbps. Now to see P3 details over sling you need at least 1Mbps, at 768Kbps the resolution will be marginal, and this is best case scenario. The old Windows XP Sling Players had the possibility to set the resolution manualy so let's say you want always low res you could set-up and the eaten bandwidth never crossed but with new player that feature is not anymore available.Other remark the audio channel even if you don;t have any sourse plugged in mono set-up will eat aprox 30-40Kbps (set-up as mono audio source, if is stereo you waste 90Kbps) and audio side cannot be disabled. I am thinking for myself to use a kind of flash server instead of sling that can be optimzed for low bandwidth, even a webcam will eat less than sling. QoS will not help you, is just a way to prioritize the packets and eventually to do limit the bandwidth but the router must mark the packets comming from a specific application or device. to do QoS If you have only one device like sling is easy to mark all packets based on IP or MAC, but in case of remoterig there are different services comming from that device so needs to be prioritize base on ports or on application level. Remoterig for the moment does not know qos so all must be done in the router, I have no clue abt Peplink but with SPA3102 is a problem, the only packets marked as Voice with highest priority are the one comming from internal sip client (used by voip ports), maybe I am wrong but this is what I remember. I am also looking for a decent blackbox solution, once I'll got something I'll post here results....let's see. Any suggestions from forum users are welcome. 73 VE3GNO Daniel

I have RemoteRigs between my two locations which will be converted from my TS-480 to the K3/0 and K3 combination. My router is a Dual WAN Peplink Balance 20 since I have both DSL and cable here. Both ISPs have troubles from time to time and the router tests each circuit every five seconds for Internet and fails over to the alternate ISP if necessary. The real bottleneck will be at the other end where the P3 will have to work through a 768 kilobit/sec. upload limit. The router on that end is a Cisco SPA-3102 VOIP router and I'm not likely going to change that or I'll not have off-premise-extension telephone between the two locations. Since it tags its own voice packets for QOS maybe it can be configured to do the same for other protocols. I'll check into it. Maybe the RemoteRig has that capability. I'll check that as well. My round trip ping time between the two locations is usually around 110 msec. which has not been a problem to date. My worry on latency is that I don't currently know what the Slingbox will add to that with its video buffer. I know it will be some but I really am not sure how to measure that from one end without a real time reference as to when the video was sent. I guess I'll just have to try it. Good ideas Daniel.
