I thought I will share my stats after my line got fixed last month. At least one decent engingeer could find and fix it properly
imo i wouldnt bother using a asus router they dont work properly with uk fttc dslam's and are not sin 498 approved.
I've had ax82u and the older version and not once in 5 years have they re sync'd ( lowered snr or increased data rate )
i got my line reset about 12 days ago and the smart hub 2 has already lowered my snr to 3 and increased my line speed.
