![]() ![]() In total the cameras account for 40mbit/sec of traffic. but all nodes report phy rates in the 600mbit and if they actually ran at that speed in both directions i'd be happy. maybe i should stop it before looking at the bit loading diagrams to see if it has something to do with that. i don't think the security camera traffic is what's borking the network as i've stopped it to run the iperf3 tests. It turns out the cameras are all connected to a single moca endpoint (via a switch with POE ethernet connections) and there happens to be a wifi access point there too, but that one is lightly used. Here is the node map about a half-hour after rebooting all the nodes (after the switch to D-high) there's a POE filter in front of that first 2-1 splitter. where the service enters the house there is a 2-1 moca splitter with one output going to the attic and the other going to a moca endpoint on the first floor. currently i have a 4-1 moca capable splitter there. my cable plant is pretty typical i think - home run from comcast entry to the attic, where a splitter feeds all the rooms. ![]() we did have our electric service upgraded a couple of months ago but aside from being near where the cable service enters the house from underground, that doesn't seem related. in theory the transmission line losses should be lower at lower frequencies, right?īased on the bit loading diagram and moca spec it seems that moca 2.0 is using 2 bonded channels, is that correct? 2.5 would increase that 2.5x to 5 channels of the same bandwidth? seems like the channels need to be narrower given the ~500MHz total bandwidth available.Īnyway, i can't point to anything that has changed. the bit loading diagrams and powers looked pretty bad both before and after this switch.Īfter all the WFH is done today i might try going down to Band D low and see if there are any changes. ![]() it may have just been power-cycling all of the moca nodes that improved things for a while. however after a couple of hours the network returned to its old slowness. however, there were other moca endpoints in the system connected to machines with gigabit nics which see only 30MB/sec sometimes, including the very asymmetrical one which of course has a gigabit NIC.įor fun i switched to Band D High from Band D extended and at first things seemed to be working better. i happen to have an airport extreme hanging off that moca node and 802.11ac clients show much higher bandwidth at that node. Part of the 100Mbit problem was that a single NIC on one machine autonegotiated to 100MBit for some reason. i did disconnect the modem and observed no change on the moca network. i don't actually think there's any conflict here. currently using channels 40-47 so 645Mhz-687Mhz. I reseated everything yesterday all open connections are (and were) terminated with 75 ohm caps.Ĩ channel modem - no moca. i do have a lot of "always on" security camera traffic so i'm somewhat suspicious that this would be a good solution in general. i also need to check the status pages of all the nodes to see what they thing their margins are.īut, assuming i can't find any physical problems, the question is - are moca 2.5 adapters more resilient to signal integrity issues? if i could get to 500mbit bidirectional everywhere, i'd be happy.īeyond that i'm starting to wonder if something like the orbi pro wifi6 a圆000 system would be a better way to connect the two floors of my house. i need to run iperf3 exhaustively between all the nodes to really understand if there's a common element here. all of my splitters are 2.5GHz so i think those are probably OK. Most of the coax in my house is old, and buried in the walls, so if this is a signal integrity issue, there's not much i can do about it. at this time i'm not sure what, if anything, changed. I'm pretty sure that when i commissioned the network 2 years ago, i was getting ~800mbit everywhere bidirectionally. both of these measurements were taken with a mostly quiescent network. Secondly, i've got some nodes that run only at ~100mbit in both directions. long story short, these problems seem to really be moca backhaul issues.įirst off, i'm seeing asymmetric bandwidth between certain nodes some run at 800mbit in one direction and 100 in the other. with all the WFH going on, i started noticing intermittent problems with wifi. I've currently got a 4-node actiontec moca 2.0 network going in the house. ![]()
