Business Upload Speed - Superhub to Draytek Router Configuration

[Rob]

Our office upgraded to the VM Business Broadband Premium. This is supposed to provide 50Mbit/s download and I believe 5Mbit/s upload. http://www.virginmediabusiness.co.uk...dband_1211.pdf

The download speed tests are coming in quite close, something like 48Mbit/s. Allowing for even our own office network routing as other stuff I'd say that is quite good.

The upload speed tests are way off the 5Mbit/s, averaging 0.8-0.85Mbit/s.

The superhub config suggests:
Downstream(0)
SFID 56723
Max Traffic Rate 54600000 bps
Max Traffic Burst 10000 bytes
Mix Traffic Rate 0 bps

Upstream(0)
SFID 23109
Max Traffic Rate 5700000 bps
Max Traffic Burst 8160 bytes
Mix Traffic Rate 0 bps
Max Concatenated Burst 8160 bytes

Which I think is OK?

So should I actually be seeing closer to 5Mbit/s upload or is that a "coming soon" somewhere in the VM network?

If it was "coming soon" - and it is in some areas - you wouldn't see it set up in your modem config as 5.7mbps.

Which tests are you using?

hmm, I think this might be a problem with my office network setup, rather than the VM connection. The speedtests I was running was through my office network which has a Draytek Vigor 2920 router connected to the Superhub. I've just rewired the network, a temporary solution only, and saw the upload speed ramp up considerably towards the 4Mbit/s.

So now the issue is to track down where the superhub and the Draytek are not speaking nicely to each other.

I think I'm getting somewhere:

DHCP on the Superhub tuned off and the WAN port on the Draytek Vigor 2920 set to a static IP in the range of the Superhub i.e. 192.168.0.xxx

Firewall in the Superhub turned off. Don't really need it anyway since the Draytek is doing that.

Draytek router's bandwidth management / quality of service settings all turned off. WAN set to autobalance loads based on Draytek's autoweight policy.

Finally the WAN port for the VM Superhub connection, in the Draytek is set with an MTU of 1460.

Now I'm seeing around 5mbit/s upload
