my opinion is vectoring is not currently supported as well.
note its an opinion.
is a shame they quickly withdrawn the firmware.
wow check out this response regarding the new broadcom firmware, I wont be recommending the 8800nl anymore.
I don't think we are going to release this new DMT code, as there is issues with our hardware
The firmware also doesn't work in bridge mode,
So even tho its a newer chipset than the hg612, it seems it has less future proofing due to billion.
I also just checked billion's .au site as they make many au firmwares but not much uk, when I used my older billion devices I often used .au firmwares, but seems the 8800nl isnt even sold over there which might explain the lack of post launch support.
