Fibre broadband speed in Malaysia is up to 1Gbps depending on the package/service provider you subscribe. Main fibre broandband service provider in Malaysia are Unifi and TIME. TIME is cheaper but has limited coverage area. As a reference, monthly subscription fee for 100Mbps is RM100-130 while 500Mbps is RM150-250 (Unifi-TIME). Nowadays the internet connection is very stable vs 3-4 years ago. Hope this answer your question.
