Draktek Vigor2850 holding back VDSL speed?


[link to this post]
 
Hi Everyone

I'm having speed issues with my VDSL service (with Plusnet). I am paying for the Unlimited Fibre Extra (up to 66Mbps) but am only able to get around 35Mbps down speed.

BT Openreach came out last week and tested the line from my socket and confirmed that the line can support 55Mbps and can see no reason why I am not able to get that speed myself so they essentially blame my router as the cause.

Can anyone offer me some advice or help here, is there any known issues with Drayteks of this vintage having speed issues or is there some configuration option I'm not aware of that might be affecting it? Or is there something else I should be looking at as a possible issue?

The stats page for the router currently shows:

VDSL Information (VDSL Firmware Version: 1414c3 )

Profile State UP Speed Down Speed SNR Upstream SNR Downstream
17a Showtime 14256 (Kbps) 36754 (Kbps) 79 (0.1dB) 58 (0.1dB)

Server Information (Broadcom v11.00.09)

If this is any help, and the router is running firmware version 3.6.8.6_232201

Advice please!

The Vigor 2850 was very quickly replaced with the 2860 and product support dropped. I'd say there is a good chance it could be the cause yes. I wouldn't waste your time dealing with Draytek support. Upgrade to a 2862 or something. The 2850 is not a good router.

There was a thread relating to this issue some time ago where Martin Pitt from Aquiss described a partial workaround - see https://forums.thinkbroadband.com/fibre/t/4579166-dr...

if i remember correctly the 2850 doesnt support Vectoring/G.INP so will limit the connection speed. You will get a better connection rate if you use something like the HG612 connected to the 2850 using PORT4/WAN. I used to run a 2850 using that configuration.
