Found another pattern that may help diagnose this problem.
SNR starts to drop 6:30pm and will make the modem drop out beteen 7pm & 8pm.
The SNR will start creeping back up again at about 10pm
One other thing; My attenuation is usually 51db but has been know to go up to 58db after a reboot.
Should attenuation fluctuate? as 7db is quite a difference!

I have similar problem.
I connect at 700kbs - 900kbs. I should be getting 2.4mbs.
I've migrated from BTYahoo where I have a solid 1mb link for years.
My connection drops periodically throughout the day.
I spoke to t3 on Monday and although they were friendly they were unable to help. I'm calling them again tonight.

I was running happily on 1mb with BT for years. If if plug into the master test socket I can sometimes get a 2mb connection but it doesn't authenticate. If I plug my old linksys router in I get 1000+kbs everytime but I don't know the username and password (and I daren't try the firmware upgrade) so it must be something to do with the router.
I'll see what they say tonight

I am not sure, I am getting higher sincs than they advised me of? Perhaps the sales team needs to be trained to make it more clear that the figure they give is a guesstimate and guidline at best.

But when your down the slower end of the spped scale a 1.5Mb error in the guesstimation is quite a large %age of spedd that is lots
Maybe they should be more realistic and give us the lower figure because anyone who gets higher than their original estimate will be chuffed to bits. But the other way just makes it look like your being short changed

It is why so many people prefer Cable to ADSL, the line stability is rarely affected on cable. ADSL is sensitive to many environmental factors beyond the control of Sky, us and BT
