Line Sync and Download Speeds

GunJack

Ey up gang I've not been round much recently, as what little spare time I've had I've been working on improving my bb speeds....and had some success :j

Internal wiring and the like has netted me an extra Mb on line sync speeds (now up to 4128 kb/s from 3095), with all main speedtesters showing 3.3-3.4Mb/s bandwidth....so far so good...

However, tiscali are unwiling to drop my target SNR margin to a 9dB profile (looks like I'm on 12dB at present, with a stable 10.7-12.5dB being achieved). A drop to 9dB should take my sync to closer to the 4.7Mb that they recon is my line's max (downstream stats are 49dB and 11.5dB power o/p)...

Sooo.....any ideas for the next step

bump....anyone got any input ??

I would have thought 6db would be a better target.
Is there any reason why it is currently 12db? Have you a history of an unstable line?

quick edit - many routers can have their snr 'tweaked' using wither custom firmware (I use dgteam's on a netgear 834gt) or via dmt tool - so you could (if you have a suitable modem) drop the target yourself.

hanx dbe...unfortunately the DMT tool doesn't work with my D-Link router or I would have used the bl00dy thing :mad: - the peeps over on DSLZone swear by it if you have a compatable router.

I have a very stable connection, it's only ever dropped sync when the exchange was down. Was asking for a 9dB profile as didn't want to try and push it too low too quick - tiscali's DSLAMs don't auto-adjust, so each time it has to be changed, it's a call to India...but so far they're refusing to even try to lower it, claiming that I've got a crap line (okay, it's not the best and around 1700m from the exchange) and that what I'm achieving is perfectly fine so No, we won't alter your profile

I'm wondering if it's more to do with the low downstream power that they can't/won't increase..if so, I'm probably burgered :mad:

I used to have a d-link...years ago...I'm pretty sure I had custom firmware for it, though I can't remember if target snr was tweakable.
plan b (or A) just buy another router...the 834gt that I use is only about a tenner on ebay (sky branded)

I have a spare (tiscali-branded siemens Gigabyte), but that always syncs lower than my D-Link....may have to investigate if it's tweakable.......
