High packet loss can be caused by a number of factors, including:
Network congestion: When a network is overwhelmed by too much traffic, it can cause delays or packet loss.
Faulty hardware: Damaged or outdated hardware, such as routers, switches, or cables, can cause packet loss.
Software bugs: Bugs in network software, firmware, or operating systems can cause packets to be dropped or delayed.
Latency issues: Long distances between network devices or multiple network hops can increase packet loss.
Environmental issues: Electromagnetic interference (EMI) or other environmental factors can disrupt network signals and lead to packet loss.
Overloaded devices: When a system is running at a higher capacity than it was designed to handle, it can cause packet loss.
Inadequate signal strength: If the signal strength at the destination is not adequate, it can cause packet loss.
Excessive system noise: Excessive system noise can cause packet loss.
Software corruption: Software corruption can cause packet loss.
Overburdened network nodes: Overburdened network nodes can cause packet loss.
Restarting your modem, router, and computer can help you narrow down the cause of your packet loss.

That's the first thing that you should do, call their Maxis SC to complain in fact for anything the related to the internet issue. Yes I'm on Maxis Fiber, migrated from Unifi 800mbps. It's probably due of your Firewalla setting. If you still have the original, try to use it without Firewalla first. Also turn off any VPN is you have one. Don't have any issue with Maxis Fiber, it's pretty stable compare to Unifi that usually lag at night probably due to high congestion.

I think its RM10 per month for the Public IP. Maxis Fiber use Private IP for its customer for security.
