SNR Drop from 12-16db to 8.5db

Ok.. so my downstream SNR has always been between 16dB and 12dB since i got MAX but for the past day or so my SNR has dropping as low as 8.5dB and i cant figure out why US snr and atten has not changed since i got max so thats ok..

Just wonding if anyone has any ideas as to what could be causing this drop.

Thanks for any insight!

is your sync rate up at all?

im synced at the max 8128 and always have been

Is this at night time Sean, or any time of day? If there have been no external changes that you are aware of with your wiring then what about round your desktop, has anything changed there? Are any of your power cables now touching or running close to the ADSL lead [Router to phone socket cable] as this has been known to drop S/N down a few db. Also what about the eithernet cable? Router should filter out any interference this lead may pick up but if the router is not doing its job for some reason then this too may cause the drop.

Seems to be 8.5 most of the time... gose to 9.5 now and then.. but ive cleaned up all the wires.. they were a bit of a mess lol but its made no diffrence at all.. theres no eathernet cabled pluged in to the router.. access is via wireless

Sorry Sean, had to have a lie down for a while.
Are you sure nothing has changed between your router and the phone socket? Are you using the standard master socket faceplate, any extensions at all that have had something plugged in or turned on when they weren't prior to this occurring? Does you main cable come direct from a pole to the master or a junction box before it hits the main socket? You've probably looked at most or even all these things by now so forgive me if I'm going over old ground. Is any of your cabling under the floorboards at all and might have got trapped somewhere through doing a bit of shifting things round or having a floorboard up?

Anything you can think of that you may have done since noticing this drop that may be the cause? If none of the above and you've not had any storms of any sort then unless it improves over the next couple of days it might be down to checking with BT to see if its at the exchange end. Have you given Zen tec a call to see if any test they can run might help pin it down?

The ONLY thing thats cahnged/been done is my mum used her laptop to connect to her work network thro dialup and thats it but the wires/connections are all back the way there was. all the rest of the cabling is fine to..

BT Pole > House > Master Socket > BT Extention > 2nd Socket > Filter > Phone & Router

And the extention is only 5 meters long

It's best to put the router at the master socket with a filtered face plate... then Cat5 to the PC's

not possible...

If i put the router at the master then the wireless wont get to my pc and i cant use cat5 cables... thats why i got a WIRELESS router...

why complain then? it could be something trivial such as interleaving being switched off but if its working its probably not worth making a fuss about
