XR500 robbing modem of 12Mbps ?

[Toxic Smoggie]

I've a similar problem myself with the HG612, where it lost at least 10 mbps download and 6 mbps upload.

 

I had this connected for a few weeks and was getting speeds of 43/13 (download\upload) when doing a speed test and also what was reporting on the XR500 when checking the internet speed from the set up, from the HG612 stats program it was reporting:

 

Sync (kbps)    56513 20000

Attainable rate (kbps)    61348 21870

 

Now the cabinet I'm on is an ECI cabinet, but today my speeds decreased from 43/13 to 29/12, not much lost in upload speeds but lost a further 14 mbps download speed, after disconnecting the HG612 and connecting the Home Hub 6 even though the Downstream and Upstream sync speed reports as 59.99/20 in the BT Smart Hub Manager stats, I'm now managing to get 54/18 when doing a speed test and also the XR500 picked up on as well.
