Curious event

[Rik]

For some reason, my 2700 re-booted itself (to judge by the logs and what I saw happen with the front panel lights) at 11:09, reconnecting at 3648 (3000 profile territory!), now some 800k higher than the Netgear could achieve.

I'll be interested to see if it remains stable at the higher speed.

[g7pkf]

Another 6 months and you might get higher



yes im at the big place in london again!!

[Rik]

That's cheating, Dean.

I find that sometimes my router will also reboot. I wonder if this is because it either hits a size limit on the logs (which, from memory, get cleared out on reboot), or because it thinks it can sync at a higher speed than it is currently at (in which case why not just restart the connection, the the whole unit!).

[Rik]

And that is gloating.

You'd think it would just clear the logs, wouldn't you, Lance (it does clear them on re-boot)? Ditto the re-sync - but if it is doing that, it's the first router I have known to re-sync for 'good' reasons rather than bad, ie noise.

[Broadback]

I am rather confused by this router connection business.  If (as I do) I switch off my router along with my machine every night does that mean that my router will never reach maximum possible speed?

[Rik]

It shouldn't have any adverse effect. You'll be synching at the best time (assuming you turn it on in the morning) for maximum speed, and should avoid any overnight instability.

I prefer to leave my router running 24/7, but that's just because I'm an insomniac.

[Simon]

Good question, Broadback.  I have been trying to convince my cousin to leave her router switched on, as I was under the impression that turning on and off wasn't a good idea.

[Rik]

Repeated power cycling is not good for a router (or any other electronics), Simon, but powering it down at the end of the day is fine. I just am never sure when my day will end, so prefer to run 24/7.

[Lance]

I'm too lazy, so it's 24/7 for me too!

[Broadback]

OK, thanks, a more general question if I may.  Where can I find an easily comprehended tutorial on router matters? Such as the meanings of all the stats etc, what bearing they have on speed.  while reading many posts here I find I am more ignorant than I even realised.  I often do not even understand the questions, let alone the answers.

[Rik]

I don't know that there is a broad-based tutorial, tbh. I just lurked around places like ThinkBroadband, reading everything I could.

Just bluff your way through like everybody else.

[Rik]

That too, Ted.

[Wingnutz]

Blind them with science or baffle them with bull@#@# !

[Rik]

I'm pure BSBB myself. 

[Rik]

I am wondering if I've discovered why the 2700 has such a stable noise margin normally. Below, I show the Routerstats output for late afternoon. My margin has fallen from 9db to 6db, with the odd excursion to 5db. I've never seen the 2700 show so much variation before. OTOH, to achieve the higher sync speed, it's used some of the higher frequencies it normally leaves well alone.

So, could it be that the 2700 is more stable because it is good at negotiating the frequencies when it syncs?

Just thinking aloud...

[Den]

I never see the point in turning my router off at night. If I am syncing at a high speed, turning off and then back on again for no reason might mean I re-sync at lower speed, so I leave well alone. 

[merlin]

just after i got my first ever router, and had just joined "heaven on wires" (idnet of course)
i asked idnet techies about switching off at night,
and they said switch modems off if you like, but never routers, as sometimes they see this as a fault and lower the sync rate.

i do,nt understand it but they did !!!!

[MoHux]

I have tried both, switching off and leaving on.

Now I switch everything off at the end of the day, because I found that even though I slept, the router was subjected to external happenings overnight.  Meaning that some mornings I found settings had been adversely affected overnight.

I found that when switching off correctly, the settings were remembered, then continued where they left off at next switch-on.

[Simon]

How does one switch a router off 'correctly', Mo?  My cousin's is a Netgear, and there's no 'on/off' switch, so it's a question of powering off at the mains.  Can't see any other way of doing it. 

[MoHux]

So o o o .........   







Edit: I was thinking rather the powering down in the correct sequence as a whole Simon.
There is no on/off switch on my DLink DSL 524T either.   

[Simon]

Oh OK, yes that makes sense, Mo.    They are paranoid that someone will piggy back their connection if they leave the router switched on, even though they have WPA enabled.

[Rik]

If you pull the mains brick (or throw a switch at its socket), the router sends a 'dying gasp' signal as the voltage drops, effectively saying to the DSLAM "there's no fault here, I'm just powering down..." At least, that's the theory.

[Simon]

Would that work the same by pulling the adapter plug out the back of the router?  Surely it would be simpler if they just had an on/off switch!

[Rik]

Neither would work as well, Simon, as both will cause an abrupt cessation. It's the decaying voltage, as I understand it, that triggers the signal. That said, if you're only doing it once a day, it shouldn't be an issue anyway.

[Simon]

Right, I understand.  Never thought of decaying voltage in that way before.  Oh well, I'm not going to nag them anymore.  It was hard enough over the phone, getting them to set up the router!

[Rik]

It always is...  8)

[Sebby]

I must remember to look in this section as now I've missed this whole thread.

I'm another one that leaves the router connected 24/7. Switching off once a day shouldn't be any issue and the exchange certainly shouldn't see it as instability. The thing that worries me is sync'ing lower the next day, the profile dropping, then having the hassle of trying to achieve higher sync for the next profile up, and so on.

[Rik]

You should be seeing a distinctive icon, Sebby, if there's posts on this board. Check the legend toward the bottom of the index page for an illustration.

[Sebby]

Ah yes, I see it now. 

So how's your 2Wire getting on, Rik? Are you still holding sync at this new high rate?

[Rik]

Yes, but whilst it would hold sync with a NM of 9db +/-2db at the lower speed, at 3648, it's dropped from 9db to 7db, with occasional excursions to 6 or 5db, so the extra frequencies seem to be much more affected by noise.

[Lance]

As long as it doesn't fall any lower you should be fine!

[Rik]

And so far, I am.

[Rik]

Result! 

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 3000 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  3648 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 2825 kbps

That's an increase of 1000k in the profile since moving to the 2700. 

[Sebby]

Very impressive, Rik.  8)

[Rik]

I was pretty chuffed, I do confess. In percentage terms, a 50% increase is even more impressive! 

[Den]

Just love the moment when I can say "I told you so" I bet you are glad you listened in the end Rik. 

[Rik]

Indeed, master.

[Den]

That was not humble enough Rik, Please say it with feeling. 

[Rik]

Ifnedeeeelding, oh master. 

[Den]

Great to see you getting better speeds Rik, it just goes to show what can be achieved with the right equipment. 

[Rik]

Mmm. Bites tongue... 

[Den]

Not to hard I hope 

[Simon]

It's not the equipment, it's how you use it that matters! 

[Rik]

I smooth and filter its power supply and shield its input... 

[Den]

Did not make any difference until you bought a 270HGV 

[Rik]

I added a UPS for the 2700, Den.

[Den]

UPS a daisy 

[Rik]

UPS a profile step. 

[Den]

at least it was a step in the right direction

[Rik]

Boom boom 

[Sebby]

So do you think the power conditioning has helped then, Rik?

[Rik]

Probably not, Sebby, but you never know. I do think the 2700 has helped though.

[Sebby]

Without a doubt the 2700 will have helped; it's that good!

I'm still looking for an excuse to buy a UPS. 

[Rik]

I already have four... Why wait.

One for the 2700, one for the computer, one for the monitor and external HDs, one for the old machine.

I'm just paranoid.

[g7pkf]

Without a doubt the 2700 will have helped; it's that good!

I'm still looking for an excuse to buy a UPS. 

In a word filtering a good ups is one of the best filters you can get!

i use an apc 1400 runs my telly, media server web and emailserver, switch and router. as well as the radio gear i have on 24/7.

i genrally use a laptop so thats on battery most of the time no need for a ups

[Rik]

I actually used to run my lappy on UPS when it was on mains, Dean, just to stabilise the voltage, which tends to regularly go over here, 249-250V is not uncommon.

[g7pkf]

True.

My laptop psu is rated 90-260V one psu for all market's

[Lance]

Great result with the extra speed Rik! What's the noise margin like? Still up and down, or has it settled again?

[Rik]

It's 9db (my target) during the day, dropping to 7db when the street light on my front lawn comes on. I've actually been able to correlate the cause over the past few days when the light has been coming on during the day. Now, can I persuade the council to relocate the light??

[Lance]

Nothing a little vandalism can't sort! 

[Rik]

A few turning lorries have tried.

[Sebby]

Now, can I persuade the council to relocate the light??

Unlikely, but you may be able to get them to have a look at it; there may be a fault.

[Rik]

I can try, but I suspect that if it's working, it's not faulty by their standards.

[Sebby]

Probably, but it's worth a try. Some people on Think Broadband have been successful.

[Rik]

Our council presides over what it terms as managed decline - iow, they can't afford to maintain things properly, so they are letting maintenance go as a matter of policy.

[Sebby]

Ah, well perhaps it won't be so easy then. Still, at least it doesn't cause your connection to drop; I know that can happen. 

[Rik]

If that starts to happen, I might just disconnect it.

[Sebby]

Good plan, although you can bet your bottom dollar that they'll come and reconnect it.

[Rik]

That depends on just how much dynamite I use. 

[Sebby]

 

All that trouble for a stable connection. 

[Den]

Who said anything about horses? 

[Rik]

 

[g7pkf]

Skip lorry took out about 2metres of my hedge tday.

i can send driver 's details to you Rik.

Im funny like that Building regs/planning application state i cannot alter my hedge i didnt the lorry did (LOL)

covered my arse by getting photos of the lorry (inc number plate in the hedge).

Mud Mud Glorious Mud

[Rik]

Looks like a good rugby pitch, Dean.
