Leave Router/modem on.
« on: May 21, 2006, 07:52:18 PM »

Read this on another forum, quote:


 BT say "Leave your modem / router connected, DO NOT TURN IT OFF"

After speaking with BT yesterday, they advised me to keep my router connected and DO NOT under any circumstances turn it off. This is new information from BT Wholesale to all ISPs, except, ISPs are not telling thier customers. This only applies to new customers of MAX products.

BT went on to say "The process of converting your line to MAX is called Line Training. This is where your local exchange over a period of about 10 days, analyses your line. If you turn your router / modem off, then the line training sees that as dropped packets and has to hault until you come back online. It will then commence again from where it last saved its data. This makes the process of Line Training longer."

So there you have it folks, a message directly from BT.

I should mention advice from PlusNet who state that routers/modems should be reconnected frequently over the first ten days of the MAXDSL service.  The PlusNet link to this information is

I do not think that this contradicts the advice from BT kindly brought to our attention by bob.gas.

Its interesting becuase in that BT max video (link is posted somewhere on the forum) the advice is to disconnect for about 15min or something each day (remembering off the top of my head).

So now the official advice is not to?

Edit: I am only referring to the 10 day max training period - not everyday use - just mentioning that incase anyone didn't know in what context i was talking.

hi hake - welcome to the forum :)

There does seem to be varying reports on this, and I can see both sides.
From experience it would seem that if you know which date you are going to be MAXed, then you are best leaving your router off that particular night if possible, so that the first time you sync up on max the DLM has the best chance of setting your bRAS profile correctly.
The problems is that everyones line is different and has such variations that I dont think there is a set rule that can apply to everyone all of the time.

My own thoughts are if you sync up at the max speed for your line and you are stable then you are probably best staying connected for as long as possible.

SNR can and does vary throughout the day, therefore if you resync in the evening there is more of a chance that you may sync at a lower speed.

It is possible that you may sync at a lower than expected speed, therefore trying a resync in say the early hours or the morning, may mean that you do get a higher sync speed, therefore under these circumstances a reboot could prove beneficial.

I dont recommend doing lots of reboots since too many disconnections can sometimes fool the DLM into thinking you have been unable to maintain sync, and therefore you could end up with lower speeds.

IMHO, if you sync at a high speed that you are happy with, then dont touch it.
If you think you may get a higher speed, as outlined above then theres no harm in trying.

mr_chris could be testiment to the *if it aint broke dont fix it* rules.  He had a steady 8Mb connection for 4 months. 
After moving a few things around and a couple of resyncs, he found 2Mb lopped off his sync speed and interleaving being applied.  So he was stuck with a 6Mb profile for 4 days.
During this time to get his speeds back up to 8Mb he had to do a few very carefully timed resyncs.

Therefore there isnt really a hard and fast rule.
Aside from if it works ok and youre happy - then leave alone.

I believe the information on the Plusnet site is taken from the advice in the BT video that soms mentioned.
