Re: Speed Issues...
said by gnumantsc  :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. 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? |

Well, i'm certainly curious to see
how this one happens to evolve!

Some inside joke?
Funny synopsis though.
Clue me some time. |

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? |

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? |
