|  Speed Issues...
I don't know if anyone has this but lately I've been running speedtests and get 1Mbit speed. Then I reboot my router and then get 4.2-4.6Mbit speeds and downloads go fast.
Then maybe 10-15 mins go by I'm back down to 1Mbit and if I reset my router I'm back at full speed.
WTF is causing this? It is absolutely driving me insane. I'm using a wireless card with a Linksys router running Tomato 1.25. The modem is a Gnet BB0060.
Same thing occurs even after resetting modem. |

It is absolutely driving me insane. I'm using a wireless card with a Linksys router running Tomato 1.25. The modem is a Gnet BB0060. Same thing occurs even after resetting modem. This scenario has been posted several times. (E.g.: »Sometimes gradual speed loss ~ hav to resync )
Invariably, several "helpers" show up, each one with the subliminal message "I once had a quasi-religious experience and I think your problem needs my ritual solution, and anyone who suggests anything else is a devil."
Others may suggest a rational, scientific, diagnostic approach. (me  )
ISP reps may say "we'll look into it privately."
Then there is nothing.
Did it turn out to be the OP's foolishness and the OP is ashamed to post the outcome?
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?

To the OP: If you are interested in understanding your problem, rather than having someone "fix" it for you as if by magic, I may be able to help you, but it will require intelligence and discipline on your part.
Should you choose to accept this offer:
Step 1: NEVER REBOOT YOUR ROUTER unless it is unresponsive!!!!! -- (listen to it instead)
Step 2: Never reboot your modem unless it is unreponsive!!! -- (listen to it instead)
Next time this happens ...
examine your router's log ... /var/log/messages*
was there a PPP disconnect event?
were there conntrack table messages?
do you know how to access your router's shell?
does this happen with p2p applications?
Did the modem res-sync? |

Oh, and this is a GNet BB0060B, on top of that!
Well, i'm going to be under heavy fire if i attempt
to get involved, too bad! At least set the coding
gain to 7 dB using 'DMT v2.20', that's all i can tell
before they crucify me!...

said by ex bell :said by planiwa : This scenario has been posted several times. ....... WTF was all that? Some inside joke? 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 . . .)
Here it is: »Can line noise slow DSL-"speed" without changing sync rate? |

Hi GNumanTSC,
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:

Perhaps you could publish your findings in a thread here.
As I have done undergrad work in these areas I would be interested in a peer review of your work. |

[/BQUOTE
Reboot is the first measure taken because we've all be trained by (too) many years of Windows!
Maybe "Grab the error log before rebooting the modem/router" would be a happy compromise? |

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.

I finally accessed the modem but I can't really do much via browser. I found the IP to be 192.168.7.1 and when I accessed the router it was practically a blank page that had the GNet logo on the right and very view options on the left.
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... |

Hi Hi GNumanTSC,
This is how the GUI should look like:

If it's still incomplete after returning to the
factory defaults then you're probably right
to fear that it might have been branded...
Well, i'd try this link and see what happens:
GNet BB0060B - DSL Parameter
Of course, you'll be asked for a UserName &
a PassWord...
In any case, this MoDem/Router is equipped
with an RS-232 port and there's no need for
a PassWord through there:

| Hi,
If it differs so much physically that there's a
standard DB-9 RS-232 console port then i'm
not sure i can tell you where a reset copper
trace might be - if that's what you refer to.
But, if you get access through its serial port,
then here's the command to reset this device
to its factory defaults:
reboot default
...providing that this version of the BB0060 is
still based on the Viking system, naturally!... |

It is always good to take a note of what the IP if the ISP's edge router is (aka: first hop in a traceroute) and note if it changes when you reconnect. |

Pretty interesting, I've done a tracert to get the first HOP as per OP and noted it down.
2 65 ms 54 ms 76 ms as3menmtl04.3menatwork.com [64.235.192.25]
I've downloaded Kubuntu 9.10 Alpha and speeds ranged from 330-500KB/s. The download took over 30 mins and not once did it drop, then again, I'm using my laptop with XP and not my usual desktop with Vista x64, but that shouldn't make a difference as I'm using the same hardware for modem and router.
I've been doing random speedtests while on the net and could not get it to go slower. The pings varied though but still getting over 4Mbit. |
