i am on maxis fiber broadband, i was given the TM branded HG8240H GPON, i can login to the web interface if i disconnected my fiber cable, if i connect the fiber cable, i can't access to 192.168.1.1 web interface at all. This makes me very difficult to change the VOIP setting because i can't check the connection status real time

i tried to do a hard reset of that GPON but it is still the same, anyone face the same issue and how to fix it?

I read some people claim the HG8240W has 100Mbps max and somewhere on yourtube someone commented that TM officially said 800/200Mbps with this modem is not possible.

I find that hard to believe.

This modem according to Huawei can easily do 1Gbps both up and downstream.
Unless of course Huawei is a untrustworthy company that is lying on their specifications.

But since all the world considers Huawei the only trustworthy company in the world, at least it seems
that's the case because all the world wants Huawei, we have to assume the specifications by Huawei are
correct and thus 1Gbps is easily doable.
