I recently purchased a TP-link Archer VR900 xdsl modem/router to replace my BT hh5 eci modem combo as it is an all in one solution with better wifi and I can also see my line stats.
Unfortunately after installing it I had a drop in my sync speed of around 7 to 8 mbs!
Now my line has never been great as I am some 6 to 7 hundred meters away from my fetch enabled cab.
My speed prior to the swap was around 40mbps and after the swap around 32mbps.
So I put the eci modem back on and am using the vr900 as a router only and my speeds have gone back up.
I know the vr900 uses Broadcom chips so my question is why the large disparity?
