just switched the good old Xbox 360 on , checked my connection as always before starting to play ... kept coming up MTU fault Router is showing MTU as 1500 (which it has since it was first installed ) ...please restart your router etc , now i,m a little bit wary about restarting router as i did a restart yesterday and sync started to come down ! .. Did ping test etc and its showing 100% packets loss ...Grim
anyone have any ideas or helpful suggestions
thanks in advance
wayne
well bit the bullet and did restart and things seem to have come back to normal !
however 5 mins after i did retart router rebooted again by itself ! and downstream data rate dropped from 6904 to 6649 if my connection now stays stable , how long before data rate starts to increase ?
thanks

yeh i did this and it did sort the problem , seems i had an unscheduled disconnect at around 02.30am sunday morning . trouble is 5 mins later it rebooted itself ... meaning 3 reboots in 12 hrs ..and a big profile drop ...... if the connection stays stable how long before the profile starts to recover ?
operator me restart ....sat 11/08/2012 at around 11.30am erratic performance
unscheduled restart ....sun 12/08/2012 at around 02.30am ???????????????
operater me restart ....sun 12/08/2012 at around 10.30am due to indication of MTU fault !
unscheduled restart ....sun 12/08/2012 at around 10.35am ! after the above restart !

As for the Plusnet side IP/profile setting......ah yes a very controversial subject.
It is meant to follow the BT side and is set at the BT IP setting but rounded down to the nearest 0.1Mbps.
In practice it doesn't seem to be working as it should and is the subject of many heated discussions on this forum.
It is supposed to happen within a few hours of the changed sync......but
Around 3 days seems to be the time it actually takes( from my own personal experience) . Why is there a delay/lag? -no one is quite sure - the relevant data is not being picked up correctly from the BT systems somewhere.

So one cannot predict exactly what the sync will be.
In general however higher sync's are obtained when you re-start during the daytime, and lower sync's are obtained when re-starting during the evening and particularly during the night. This is primarly due to changes in the earth's atmosphere during evening/night caused by the solar wind from the sun which cause extra radio frequency interference 'noise' to be present which is picked up by your phone line and causes reduced sync.
Some locations suffer increased 'noise' on the line during working hours (industrial units nearby) so you can see that a re-boot at around 0830 am might be a good time to avoid both ends in these cases.
To make a sync go up you have to re-start the router. Seemless rate adapation where the sync would vary 'on the fly' both up and down in response to changing line conditions was never implemented in the UK.
Regular disconnections will always worry the exchange equipment and if they are excessive it will change the line's paramaters such that the sync will always be lower (it raises the target noise margin to do this).
Note that chasing high sync is not always the way to faster speeds. If say you re-sync at a known quiet time and get a good/high sync, then during the day as the noise level gets higher the error rate on your line will start to rise. This means data is being sent too fast and is being corrupted, so the data has to be re-sent by the exchange and the packets all re-assemled by the router before being passed on to the computer. This all takes time, and the result is your achieved download speed start to reduce quite significantly - although your sync speed remains constant......until the error level becomes so bad a re-sync to a lower figure is ordered by the exchange.
