 Posted: Sun Apr 29, 2007 9:18 am Post subject: 921.6 kbps limit? |
 |
|
Hey guys, new here.
I recently ordered sprints wireless broadband with a novatel usb modem. but I got a question.
In my task manger under the networking tab, it list my link speed to 921.6 kbps. Does this mean im capped at that? is it possible to increase it? and what does 921 kbps download at? im not using the connection manager at the moment due to software problems and im running win xp.
what do you guys think?

From speedtest.net
Download - 736kb/s
Upload - 54kb/s
Does this mean i can download @ 736kbs a sec or what..
EDIT - Whats with this annoying forbiddin word deal? im not cursing

Yup. That's exactly what the speedtest is for - your download speed. You could download at 736kbps at that moment. EVDO speeds vary tremendously minute to minute due to so many variables . . . weather conditions, load on tower you're connecting to, etc.
The speed you saw in your task manager was the speed at which you connected. Remember, this varies so a minute after you connected your speed might have been very different . . . .faster or slower . . . .
BTW, you appear to be getting average EVDO Rev 0 speeds. Your UL could defintely be better. If you can get SCM running you'll be able to tune it a little better probably since you'll be able to see your signal strength and therefor you can move your U720 around a bit to find the "sweet spot". Are you using the Y-cable? |

I think what the OP was saying is that in Windows XP, the maximum speed option you can choose is 921600 bps, which the Status indicator in the Connections panel shows as "921.6 Kbps." I've wondered about this myself, because I get download speeds of 1000-1300 kbps.
Is the issue that the capital letter "K" of "921.6 Kbps" means bytes and not bits, and that's faster? (Sorry if this is basic knowledge for others.) |

Ok using the y-cable, I managed to get SCM running and my signal is flucuates between 2-3 bars with 1xRTT: -101dBm and 1xEVDO RevA: -93dBm*
This is the best spot so far i found. When you say fine tune bigdave, do you mean by finding the sweet spot for the highest signal moving the modem around? or is there more too it?
another thing is that every speed test ive done with this service, ive always gotten something over 400kbps yet the most ive held a download is about 60-70kbps. It doesnt even start off at 400kbps then gradually go down. the highest kb spike ive ever seen so far is about 120kbps, nothing more. whats up with that?

Your right, im sorry if i wasnt clear about this whole situation but yea, you got it. thats the max speed windows indicates..
And as for bytes and bits, honestly i dont know the difference. sorry for bieng such a noob, but ya gotta start somewhere, right? :p
EDIT - again, this forbidden word thing is starting to piss me off.
so I ran another test using testmy.net and came up with
Download Connection is:: 442 Kbps about 0.44 Mbps (tested with 386 kB)
Download Speed is:: 54 kB/s
Upload Connection is:: 30 Kbps about 0 Mbps (tested with 97 kB)
Upload Speed is:: 4 kB/s
so let me get this straight. if i were to connect @ 1000Kbps my downloads would range from 100-150 kB/s right?

wow i managed to change my HA and got a speed result of
download - 1148kB/s and upload 132 kB/s

You running Firefox? Your ul's should be faster than that.
This was with IE7.

I see that people still do not understand that the speed quoted is an AVERAGE of the time from start to finish and file size and not the transfer speed. The actual transfer speed is far faster.
If you study a graph of the datastream you will see there are peaks far faster than that number and lows as low as zero.
I have seen peaks of 180 KB which is far faster than the result of the test.
Also the signals are transmitted at a far faster number but the actual transfer of data is significantly less. |

That's what I meant. With the Y-cable and the SCM you can see how good your signal can get. I've never gotten better than -79dBm and normally I hold steady at about -85 but my speeds are pretty good normally in the 1200 to 1500kbps range DL and 300 to 500kbps UL range since Rev A.
I'm not a gamer and don't use VOIP so the fact that the very best latency I've ever gotten was 285ms with it normally being in the 350 to 450 range really isn't a big deal for me. If I was into gaming I'd be working on it though. I'm less than a 1/2 mile from the tower but am currently in a concrete building (an old motel we're remodeling with 3 walls of concrete and one of glass facing away from the tower) so I would think I could get a much better signal if I felt it was warranted for my needs. Anyway . . . . . keep on tuning!! Good luck. |

You can safely ignore the 921.6 kbps number. You could change it down to 9.6 kbps and it would make no difference. It is there because Windows treats your U720 as a serial COM device using a virtual serial port driver.
What this basically means is the U720 driver "lies" to Windows, making it think it has a serial port device. This way, you can use things like Windows DUN, even though you have a USB device. But all serial port deivces in Windows must have a baud rate set. Yours is set to 921.6. Mine is set in the 200 kbps range. I still get as high as 1280 kbps down and 700 kbps up which appears to be about the limit of a Rev. A tower with a single T1 line.

Well after hanging out with you guys all day on my day off, i managed to set my SCM to only recognize EVDO (disabled RTT) and by switching the HA i went from a crappy 300-400kbps 100dBm to 1000-1200kbps -86dBm. I may still tweak it a bit more to get better signal. I just wanted to thank you guys for all the help and time. now i have some explaining to my gf on why i spent all day on the computer and not with her

Hi
What is HA as in " by switching the HA i went from a crappy 300-400kbps 100dBm to 1000-1200kbps -86dBm."
Also, the 'word' not allowed may well be a special reserved character from your keyboard rather than anything you wrote.
