Just updated my router form a VR2800 to the VX1800v and almost all is good so far, no issues with wifi but for some reason the Ethernet (internet) speed is roughly half that of the wifi.

 Wifi is coming in at around 64mbps - which is acceptable for the current VDSL connection, however Ethernet is half of this at 32, previously with the VR2800 the Ethernet connection was slightly faster than wifi

The VX1800v is connected exactly the same way as the VR2800 was using the same cables, the only difference is the router
