Hi sifus,
I’m currently facing a very strange connectivity issue with Maxis Home Fibre. My internet suddenly went down, and since then I’ve been unable to reconnect using my own router.
What’s happening
My router log repeatedly shows PPPoE authentication failure, even though the discovery phase completes normally. Below is the relevant part of the log:

What I have triedCalled 123 to get a new PPPoE password → still authentication failed
Tried with my TP-Link BE65 (Maxis VLAN 621 on Unifi infra) → same error
Reconnected the original Maxis router → it can authenticate
BUT when I check the router UI, the PPPoE password field is blank
So I can’t retrieve the actual working password.
What Maxperts didMaxperts came to my house, but unfortunately they could not resolve the issue.
Here’s what happened:They noticed the PPPoE password shown in the Maxis router is blank
They also could not explain why the password is missing
They tried to push a fresh configuration from the Maxis backend
→ still failed
They suggested maybe it’s the router issue
→ but as a software engineer, I strongly believe this is not a hardware issue
To me, this clearly looks like a Maxis backend / PPPoE provisioning problem, not a configuration issue on my side.
My Temporary workaround (but not ideal)Right now, the only way I can get online is:
Use Maxis router just to authenticate PPPoE
Disable WiFi on the Maxis router
Run my own router behind it in DHCP mode
This works, but it’s not optimal because:
I cannot achieve full 1Gbps throughput
(Maxis router LAN port is only 1Gbps, while my GPON and main router are 2.5Gbps)
My setup was running perfectly fine for months
I did not change any settings — it just suddenly stopped working
Current situationOnly Maxis router can authenticate PPPoE (even with blank password)
Any third-party router → fails authentication
New PPPoE password from 123 → also fails
Maxperts → unable to fix
At this point, I’m quite sure this is a backend authentication issue on Maxis’ side.
Has anyone encountered this before or know what might be causing it?
Any advice is appreciated!
If you need more details about my setup, I can share.
