Is this as good as it is going to get?


[link to this post]
 
Moved to 21CN on 19/03/2013
Upgraded to Zen Active "upto 20Mbps" on 22/03/2013

From the Stats, in the link in signature, is this as good as it gets?

Downstream SNR has dropped from 9dB on ADSL to 3dB on ADSL2+, after a couple of resyncs in the first few days.
Upstream SNR has dropped from 30dB on ADSL to 5dB on ADSL2+, since the upgrade.

Are the Errors anything to worry about. Are they slowing is down?

Telephone lines comes from pole to master socket (nothing plugged in here), one extension with twisted pair CAT5 Cable to socket, surge protector and filter to one dect phone, ADSL side has 5m of Shielded CAT5 Cable to router.

Thanks for any advice.

Would expect about 22 Meg @ 3 dB NM.

Unable to assess error rates w/out "Total AS" cut off bottom of display or Time Connected.

Thanks XRaySpex for the reply.

That is the last line "Total UAS" and it is 0 (zero)

Time connected when screenshot was taken was Approx 112hrs.

Though BT normally use Broadcom gear at the exchange MSAN, they have been known to use Infineon/other chipsets. Since the Billion 7700N uses a broadcom chipset, it won't be getting the optimum sync assuming your exchange has a non-broadcom chipset. Try alternative routers such as Netgear DGN1000, DG834G (some versions) and you may find your sync speeds increase by a few meg.

For 16.5dB attenuation the sync is in the expected range, and you might squeeze a bit more, but is it worth the bother to shave a few seconds off the odd large download

I think Andrew has a point.

As someone who has tried numerous Netgears and other routers to get a stable line (which is long anyway) and a good bit of speed I've found the Billion I have now to be the most stable bit of kit I've had so I'd really leave things be if I were you.

That's not quite true, I'm afraid, BT hardly EVER use Broadcom MSANs. They usually use Infineon or Fujitsu, or sometimes Huawei (a VERY, VERY poor choice).
