So I got my new Sky Hub

[joe pineapples]

I used to Get this (for over 2 years stable)...



Then a few months back it dropped to this

ADSL Link Down Up
Connection Speed 8377 kbps 838 kbps
Line Attenuation 40.5 db 21.6 db
Noise Margin 7.0 db 6.5 db

So I decided to replace my old Sagem 2504 with the new Sky Hub (hoping I might claw back my original speed at least, with a possible lower snr target margin after line training again). When I first plugged it in, it sync'd more or less the same as above, but overtime (same day) dropped the snr down to around this this...



I haven't touched it since first switching it on and it has kept the same pattern every day....around 4.5 during the day and dropping to around 3 in the evenings (about the same drop difference as the Sagem), with no re-syncs/disconnections. Just not sure what is going on. Frustrated that the snr has gone down but the sync speed has stayed the same. Also a bit worried that if I reboot it, the system will see the lower snr and drop the sync even lower.

Note that I haven't asked Sky to retrain my line yet and the 'mysky' website message above has remained the same.

Have you checked this with the router plugged into the test socket using the filter and cable supplied with the hub? The difference in noise margin between day and evening isn't that great but if it persists with the router plugged into the test socket you might like to check that all other phone sockets in the house are dead and do quiet line checks from the test socket using a corded telephone to hear if there is any discernible increase in line noise during the evening.

Can you plug your Sagem in again and see what result you get? Different routers perform differently on different lines. My SR101/2, DG834GT and Sagem 2504 all sync at about 11200kbps, but my DG934G only syncs at 10100 kbps. All with a 6+db margin.

There is no test socket as such, as its an older BT master socket. It is plugged directly into that socket though using the same XF-1e filter and round RJ11 cable I used with the Sagem. No extensions and tried a quiet line test a while back with a corded phone. Only change between Sagem and New hub is location slightly different by about a foot.



Sagem used to be flat under the unit (left in picture). I'd also previously (with the Sagem) swapped the XF-1e with a generic one and no difference (stayed at 7db at that time). I probably will test the SKy Hub with the cable it came with but tbh the round (molded ends) one I bought specially ought to be better quality, unless something has happened to it, but was fine with the Sagem

Can do a bit later.

Won't be able to try anything while tomorrow now, but just wondering if there's a set number of forced disconnections in a certain time period which will trigger line training?. I intend swapping out routers, cables etc a fair bit tomorrrow, but I don't want line training being invoked until I'm happier for it to do so.

thanks
