Sync speed & Noise margin
Would your Sync speed drop during high usage by other users.
Would this also make your noise margin drop.
Because this is what Tech Support have told me.
At 8:00am my downstream has lost 1200kbps from the figure I was getting Thurday and Friday until 7:00pm
If I phoine BT and ask then to increase the gain on my line would this make things any better?
I have already disconnected the ring wire and tried the master socket.

high usage would affect your download speeds, but it should have nothing to do with your sync speeds. Your noise margin will usually drop in the evening, mine drops from 31 to 26, and sometimes lands at around 20. A connection which keeps dropping because of margin could cause a lower sync rate

im not totally sure, but i dont think other users affect the sync speed or noise margin, they would obviously affect the download rate.
im pretty sure that increasing gain on a adsl line doesnt help and that its for 56k modems.

Actually yes, lots of users will cause the sync speed to go down, because of crosstalk. This is quite a serious problem and it's only going to get worse as more people switch to higher-powered variants like ADSL2+.
There will be a pattern at peak times when everyone switches on their ADSL modems/routers that sync speed will go down -- exactly how much (if at all) this will happen is down to external factors.

I've phoned Sky Tech Support twice today as I had more lockouts at 7:30pm
First thin I got through to a non-UK call centre who were as much use as a chocolate vindaloo The said lost of users on at once.
Tonight I got through to a nice chap in Scotland. He said it sounds like a faulty modem and they will send a new one out. No mention of returning the old one. He is also forwarding my problems to tier 3 for line tests.
I asked that because of problems and retesting it may take me over the 8 day cool off period. They reply was that I would be able to exit my contract after the 8 days if the problems are not resolved.
I hope they can resolve the issue as I would like to stay with Sky but at the moment going back to blueyonder means pluging the RJ45 back in my netgear and powering on the router and modem
Anyone know the model number for the cable version of the WG835GT as I would like to upgrade my 802.11b router for a 108n version as I've already purchased the USB adapters from Sky. Just in case I have to go back to cable.

I'm having exactly the same problem at around 730-8pm every night since I was actviated the router has disconnected. The download SNR drops to below 5 ( my old Dg834G used to work fine at 0) It's staying sync'd up but it's lost the ppp connection! I have to reboot the router to get things working again..
Called tonight and she was more concerned that I didn't have any virus software running (I'm on a mac) and that I was connecting to the router via wireless.. The fact that the router status page was saying that the ppp connection was down did not concern her. She would not pass my call on to anyone else until I had tried using ethernet etc.. and I should give it 10 days to settle down..
I don't mind not having the full 8meg even 2 meg would be find (what I had before) as long as it was stable...

have you got anything in common at that time?
ie central heating coming on or anything on a timer?

I read on another forum that a neighbours treadmill was causing interference

But we cannot wait 10 days for things to settle as they only give us an 8 day cooling off period after activation
This woman was a muppet you should try phoning again and tell them that others are having the problem forwarded to "teir 3". It's pot luck to how far you get a the support people all have different skill levels.
I did inform the support bod I spoke to that I run my own computer support business (So he could not bulls..... me).
I should be getting 4.5Mb as the BT adslMAX checker says even CS said I would get 4Mb but I have bee down as low as 2Mb after rebooting when the modem dropped out
I have fond the Netgear WGT624 is the cable version of the router and Amazon do them for £49.00. So if I have to drop Sky I'll get one of these to replace my old netgear 802.11b
