Exactly as billford says, no.
and whoops, sorry for the duplication with Andrue: I forgot to press the Enter button ....
There are cases where it is necessary to reset the router (best done by disconnect/reconnect in the web interface).
The IP profile is meant to track the sync speed, which happens on PPPoE connect.
Often a modem loss of sync will force a PPPoE disconnect, and then an automatic reconnect when sync is restablished will update the IP profile.
Sometimes however the modem loses and reestablished sync without the PPPoE connection noticing,
and in this case the IP profile can get out of date.
If it is too high you won't get extra speed as you will be limited by the sync; if IP profile is too low it will unnecessarily throttle your speed.
