Hi guys, recently I just bought dual Deco M5 for my home use. For the first two weeks, the Deco M5 was running fine in PPPoE mode. However, there is no internet line today. I try to reset the M5 and reconnect all the cables but still no internet. Then, I reconnect with the previous Maxis Archer c5v router and the internet works fine. However, some features such as QoS can't use so currently running in access point mode

I already switch with another unit of M5 to set as the main router but still no internet access before setting up. Anyone solution? Should I buy those higher grades of cat6 cable in Shopee to try?

I can't even enter the setup process because there is no internet access when connected directly to the modem...
