Restricted internet

when i start the computer up in the morning i get great internet speed for this area..........

well then my son gets up and it all goes to pot.. i get only half of what i got 10 mins before.. i can understand that as they both need internet and it gets halved..

he has a ps3 and is on it all day long.. but after its turned off it stays the same and doesn't return to the speed.. no matter of resetting the computer or router will rectify it..

Perhaps by the time the PS is switched off there are lots of other people surfing?

Could you post your line stats? See http://www.dslzoneuk.net/adsl_line_stats.php

What time does he stop playing it?
Who is your ISP?
Have you considered the time he stops playing the PS3 may coincide with a speed drop from your ISP, because it may be their busy period?

i can understand that as they both need internet and it gets halved..

That's not how it works.
If you have three devices sharing an internet connection, your available speed isn't divded by three.
Each device takes what it can get.
The PS3 doesn't use an awful lot of data for online gaming.

I think you need to provide us with more information (to prevent us from just guessing).....
Post your stats (available from the webpages built into your router).
We need to know;
Connection speed (up & down)
Line attenuation (up & down)
Noise margin, or SNR (up & down)

Also tell us which ISP you're with, and what package you're on.

I wondered whether the PS3 is giving noise somehow, so clobbering the sync. But then a reboot of the router afterwards should help, even at heavy times.

Not seen a PS3 as a cause for slow broadband

Switching on a PS3 should not mean masses of Internet usage, unless the person has a lot of demos queued for background download perhaps, and it may be these are triggering ISP traffic management

The line is not very stable. Could be bad house phone wiring. Try disconnecting the ring wires to start with.

have done that.. but still doesnt do anything
