Speed Issues... in Canadian Broadband http://www.dslreports.com/forum/r22562661 en Sun, 06 Dec 2009 08:19:05 EDT Sun, 06 Dec 2009 08:19:05 EDT Re: Speed Issues... http://www.dslreports.com/forum/remark,22627944 gnumantsc : Ok here is a bit of an update. Never type clear in console of the modem hehe.

As I said, I do appreciate everyone's help on this issue. I had to reflash the modem as I typed clear. I made the mistake in thinking that I had the bb0060 modem when in fact I had the 50.

The firmware update gave me a proper screen to look into the settings and I will test it out some more.

Thanks to all of you and I'll monitor with the tools provided.]]> http://www.dslreports.com/forum/remark,22627944 Mon, 29 Jun 2009 11:46:35 EDT Re: Speed Issues... http://www.dslreports.com/forum/remark,22587307 planiwa :

I'll post the log here from what I get from Tomato, maybe someone could "decrypt" it for me.

I did not check the connections with the QoS Graph. I could check it out and see.

It is not that I don't show interest in the issue, but I am having a hard time getting the darn modem page to work to see if I could get any info off of the modem itself. I tried multiple times to connect to the net without the router and just PC with modem and then running DMT tool but for some reason I was getting errors 691/718 which I know have to do with credentials.
I know that it is easy to become consumed by struggling to pursue a singular path ... possibly to its dead end. :-)

My preference is to take a broad, open approach, and not disregarding low-effort, high-insight diagnostic measures.

But whatever works, works, and it may well be more important to do what one feels one must do and be happy, than to try to employ methods that seem obscure, pointless, strange and unnatural, even though they are natural, easy, and effective for others.

Well like I stated when I got kicked off the net and checked my uptime it showed like 5 minutes. I didn't reset the modem at all during the .25 and as I stated I was playing with speedtest the whole time and downloading and was getting between 330-515KBps.

I don't know why I got disconnected though in the first place while gaming, which got me a bit confused. The connection dropped completely.
Did you lose sync?
What did the router's log say?
Did you check how many connections, with QoS Graph?
Oh, I seem to be repeating myself. :-(

Here's a bit of logic for those who may have a use for it:

If you get a reliable speed measurement at 4.2 Mb/s, then, as long as the modem does not resync, you *know* that any "speed" or "disconnect" problem is not a DSL issue.

(Any "speedtest measurement of more than 4.3 on a 5Mb/s profile is bogus.)

And something from experience:

Any "speed", performance, or "connectivity" issues that do not involve modem re-sync, but are associated with P2P applications are most likely rooted on the near side of the DSL link, and most probably due to NAT/conntrack connection surges.

Perhaps someone else with a similar problem may benefit from it, along with the suggestions I made in my first message in this thread.

I find it uncanny that the OP showed no interest in learning about the problem condition when it presented itself again, even after having received specific guidance about what to look for.]]> http://www.dslreports.com/forum/remark,22585829 Sun, 21 Jun 2009 03:12:36 EDT Re: Speed Issues... http://www.dslreports.com/forum/remark,22583698 Bicephale : No, wait!

Why is it always the GNet modem that has issues?

Funny I was only me having this issue and I called every day to report the issue and the time it was happening with full tracerts.

How come I can't always be routed through .25 and we could make it easier for the both of us? :) I guess I'll have to hit up diskace for a loaner modem as I don't know anyone else with a spare modem.]]> http://www.dslreports.com/forum/remark,22582303 Sat, 20 Jun 2009 09:19:18 EDT Re: Speed Issues... http://www.dslreports.com/forum/remark,22580661 Briaeros :

Diskace could you elaborate on this finding?
Interesting, so you're saying that you weren't having any issues at all when your first hop was .25 but now that it's on .24 the issue seems to be back?
That could be pointing to either a hardware issue pertaining directly to the .24 gateway or depending on a few background details (model of the actual gateway) it could potentially be some kind of compatibility issue between that gateway and your modem? I know we've had numerous troubles with GNet modems, the surefire way to know if it's a compatibility thing or not would be to simply test with another modem and compare results.

I would also run two ping probes from the router each time I reconnect, and save the results:

ping -q -c 20 -s 28 $( nvram get wan_gateway)
ping -q -c20 -s1420 $(nvram get wan_gateway)

If it differs so much physically that there's a

then here's the command to reset this device

I bought this modem years ago from a person who worked at Inter.net and I tried the default passwords of DSL/DSL and root/root and couldn't do much.

All I saw was DSL stats which showed 5052/512 sync rate and that was it. Probably inter.net bastardized the modem so you couldn't do much.

Now if I only knew the password...]]> http://www.dslreports.com/forum/remark,22570954 Thu, 18 Jun 2009 09:07:59 EDT Re: Speed Issues... http://www.dslreports.com/forum/remark,22568609 Briaeros : I've seen similar cases before, the actual line profile is unchanged but the modems actual sync rate is down. Rebooting the modem seems to fix it yes but it's obvious that it must be caused by something.
I've noticed that it never seems to occur on certain brand/models such as the Thomson modems.
My guess is a combination of noise and/or errors on the line + the modem has some kind-of feature to automatically lower the sync rate to compensate. The trouble causing the modem to lower sync rate must be minor enough for the connection to not be lost but major enough to warrant such a severe decrease of speed over time.

Still, it doesn't change that if you want to have it fixed in a more permanent way you're going to have to check your modem logs and record all line status details you can while the modem is still slow. The answers should be contained within.

Since Planiwa's interest focusses mainly on, aHummm...
"the science of technical problem-solving" and "psycho-
social aspects of cyber-helping"! - Euh... I suppose the
chore of providing URLs to the available tools falls back
to me... So, here they are. 1st, there's the v2.20 build
of 'DMT' (and no other) which is what the GNet BB0060
requires. 2nd, there's 'RouterStats-Light' (i cooperated
with its author over the addition of support for a similar
product, the "GNet GBB2060-Xi", as it turns out i own a
BB0060B and a GBB2060-Xi as well). I strongly suggest
you obtain each of these nice trouble-shooting utilities:

'DMT v2.20' (171005 Bytes .ZIP file, 2007-May-31)
'RouterStats-Light v4.6' (1161136 Bytes .ZIP file, 2009-Jun-1)

Lets notice that the GNet BB0060B is one of the rare DSL
devices not to suffer from what i've tagged the "amnesia"
syndrome: as long as you don't reset it, the "noise" 24 h
long-term history will be available for 'DMT' to display. On
top of that, 'DMT' gives you some degree of tweakability.

As for 'RouterStats-Light', it complements 'DMT' beautifully
because it can generate long-term SNR Margin curves. One
is TelNet based while the other has an HTTP parser instead
so that means you should be able to run them concurently.



Also, here's the TelNet CLI "bible" - Planiwa might oppose
to using cute Windows GUI tools so i guess you'll need it:

CLI Reference Manual (DO-300171-TC-7) for Viking & Viking II Chip Sets, 5M3

Additionally, here's the User's Manual:

TurboCom EA130 User's Manual v1.0

Remember, try to set your Coding Gain using 'DMT v2.20':

»GNet Tweaking

The "Coding Gain" item is on the lower-right of my image.

Apply then reboot.



As for the rest, it would be premature for me to point you
at a specific thread or post and i must warn you that i've
wrote quite a few anyway... Maybe you'll want to browse
through it all later, maybe not. In any case, here's some:

Funny synopsis though.

Clue me some time.
The problem itself is of genuine technical interest:

... speedtest is slow
... reboot router; reboot modem
... speedtest is fast
... wait 10 minutes
... repeat

I'm sure many would like to see the outcome. I cited an example of one similar scenario, where, apparently, the frustrated user received many different suggestions, leading to more frustration, and, apparently, no outcome. (There was a spin-off thread:
»gradualspeedloss guy, now WITH VIDEO!!! TSI pls LOOK also with no outcome.)

I do hope that this thread is followed to a successful outcome here, or if elsewhere, that the OP will eventually post a summary of what the problem (and solution) will have turned out to be, for the benefit of others in similar circumstances.

I find it interesting that "reboot" or even "factory reset" is often the first measure taken, rather than one of the last to be considered.

Apart from the science of technical problem-solving, I am also interested in the psycho-social aspects of cyber-helping.

And even the psycho-socio-profit-model behind "free internet speed tests". (Isn't it interesting that "no one" "ever" mentions straight-forward, short-haul, accurate, non-commercial, through-put measures?) I find it particularly interesting when people use "internet speed tests" to diagnose DSL line-noise problems.

A question for the experts: "Can line noise (significantly) slow down a DSL-link without changing the sync rate"?

This is something else that I find really interesting. Most conversational transactions in these forums are vertical. Apparently little serious civil collaborative critical technical conversation goes on between experts.

Of course most threads are novice-problem initiated and driven. And most follow-ups are from experts trying to contribute to fixing the particular problem. And often experts do share general knowledge, but mostly "downward".

Perhaps it is easier for novices to question, to listen, and to learn?

(Maybe I'll start a thread with that expert question . . .) :-)

Was it the ISP's fault, and the ISP is ashamed to have the outcome posted?

Was it some random fluke and all is well now but no one knows why or what?

Is it continuing and all involved are frustrated to death?

Or was it all due to line-noise which never resulted in modem re-syncs, but which must have been there, because it once was elsewhere, and there are plenty of impressive animated GIFs to prove that it once was elsewhere. :-)

Or what?

examine your router's log ... /var/log/messages*
