I have been experiencing jerkyness streaming live HD TV from MythTV
over wi-fi to my work computer. SD is fine and both are fine on the
So, I concluded that it must be limits across the wi-fi.
is there /are there any programs that can demonstrate the wi-fi
bandwith and perhaps how it is bewing sliced up?
I couldn't find anything from a brief search via DuckDuckGo or google.
Why not stop worrying about "bandwidth" (whatever that means to you)
and check the actual connection speed, just like any normal phone or
laptop user would ?
Theres no mention of it anywhere in this thread
It can vary from moment to moment, and may not mean much anyway. It's
like the "bars" that you see on a typical cell phone that are supposed
to indicate signal strength in a meaningful way. :-)
I've been told about some consumer network equipment that recognizes
when one of the popular speed test sites is being used and prioritizes
that traffic so that speed test results look better. (Doing a "VW," in
I know of some other consumer network equipment that learns traffic
patterns and changes its behavior based on them. A streaming 4K video
session will be optimized because it takes place over a long period of
time. A speed test is too short in duration to be optimized for (unless
you're cheating like the other company), and it's highly abnormal usage
as well, so the results shown may not reflect real-world usage of the
I am well aware of all of that. However, there is still no mention at
all of the connection speed anywhere in this thread.
More importantly, theres no mention of any attempt to ascertain the
actual (wired or fibre) download speed from the ISP to the router (which
DOES NOT vary from moment to moment) which is more likely to be the
cause of the problem.
I would check the admin page of the router and see what the downstream
line rate is and work from there. If it looks like its OK then (if
possible) it might be an idea to make a temporary WIRED connection to
the router and see if that cures the problem. If it doesnt, then clearly
its not a wi-fi issue.
Nothing I have seen in this thread so far conclusively proves that the
wi-fi is at fault.
Pinnerite setup, described in OP
Client MythTV -- OTA
This is a question of LAN performance, nothing
about WAN or pulling Netflix or anything like that.
MythTV is capable of complicated setups, but we're not
being told about that. There can be front ends and
back ends in the picture. Tuners doing capture,
would burn up as much bandwidth as client sessions
(2 megabytes/sec per tuner?). A capture tuner could be
competing for bandwidth, with a client session trying
to watch a recording.Loading Image...
You could do an air survey or whatever. See whether
there's a better Wifi channel or band choice maybe.
Or any sort of simple LAN transfer would indicate
whether something is broken. If you can only get
11 megabits/sec during a file transfer, that's going
to doom TV streaming.
Doing speedtest.net won't help, because it's not
a WAN issue.
If a router is not supporting QOS (quality of service)
protocol options, then the router might be using nothing
more complicated than round robin. That's what the LAN
to WAN router on my network does. The higher speed portion
is done with a GbE switch. If one machine opens too many
WAN-directed connections to the router, the other machines
might not get as many slices of the WAN pie as a result.
I can just about starve a second machine (can't web surf),
if the first machine opens a shitload of connections. But
this is an issue of getting fair share on the WAN end,
which is not particularly the problem here.
Networking questions can benefit from drawings,
but what are ya gonna do.
