Fibre speed drop


[link to this post]
 
I have had fibre for several years at around 42-43 meg stable.

I had a jump upto 50meg around 3-4 weeks ago for a week or so and since then it has dropped back down to 42ish and doesn't seem to imrpove.

I am using an openreach modem and an edgerouter x.

I've tried another router and it gives the same results. Will changing the modem help at all?

I just tried several modems on my line and by far the best performer was the ZyXEL VMG1312-B10A. Others I tried were the BT Openreach modem, TP-Link TD-W9970, Billion 8800NL R2. The TP-Link is not a bad performer but let down by wireless performance.

I would suggest looking on eBay for a ZyXEL and giving it a try as I have gained about 5 meg sync since plugging it in after a very quick setup. Note the B10D its replacement has a cheaper broadcom chipset in it and is the same chipset as the TP-Link and Billion.

My sync speeds at 5dB
TP-Link - 64/17
Billion - 62/17
Openreach - 62/17
ZyXEL - 71/17

Good luck.

The OP doesn't need a modem router. He already has an Ubiquiti Edgerouter which is up there with PFSense on features. The Zyxel, and all the others you list, are [consumer] junk compared to it.

OP - your sync rate was obviously just increased by the DSLAM deciding to lower the target SNR. My target SNR recently fell from 7 to 3/4 resulting in a gain of 3-5Mbps. Same as you. This has nothing to do with your equipment and everything to do with BTO's DSLAM.

They all get higher sync than any stand alone modem does on his line, and can be run in bridge mode as a modem only, with the Ubiquiti Edgerouter handling PPP, NAT, etc.

Probably a crostalker on holiday for a week; they switched off their router.

May do; only trial and error and monitoring stats will tell.

Best for the OP to use them in bridged mode.... not as a router

Surely what the OP is reporting is DLM attempting a lower SNR, but errors forcing it to back up to 6 again ?

That's exactly what is happening. This fixation from others concerning replacing hardware to improve line speeds is grossly misplaced.

Not always.

Some routers are much better and dealing with errors and are able to attain and maintain higher connection rates.

DLM attempting a lower SNR

That is another cause; I hadn't thought about that; but without stats we will not know 100%
