Hi i Had the same problem creep back up as i did before, virgin media did something on their end and i have Okay not good internet for about a week or 2 and then it goes plop again, i had a senior engineer come out and he said he found the issue, we even had a new cable that leads out of the house. I have spent so much money trying to get a stable connection but nothing working.
i have the hub 3 in modem mode linked to an Asus RT-AX86U router which then has an ethernet cable to my PC (cat 8 cable). There is nothing wrong with my equipment
when entering the network log on the hub 3 i have this constantly every couple of min
