Hello sifu, I have some questions/issues facing for TM UNIFI 300 mbps (free upgrade from the 100 mbps).

1. Currently I am still using the default TM wifi router for like 3 years now. It is starting to be unstable i.e., occasional disconnection for a few seconds especially during the night time when my housemates are home and using the wifi. Is this because of the router starting to be faulty and unable to handle the big data stream?

2. I have a Fiberhome SR120-A that I brought from my home. I tried to set it up by myself, however I am not able to connect to the internet using it. Based on my searching online, I need to go into the Advanced Setup in the backend, but my Advanced Setup only has the Quality of Service (QOS) option. Those online guides and videos have the set up internet options in their Advanced Setup. Anyone used Fiberhome SR120-A before and know how to make the options appear?

Thanks in advance.
