That one is Astro & Broadband.
Astro & Broadband versus Astro Fibre are 2 different things.

Astro & Broadband commonly known for providing you Maxis Internet + Astro TV subscription in one Astro bill.
And you'll be getting Maxis Fibre router, and also using Maxis VLAN ID of 621.
If you do speedtest or check the IP address, you'll see that your ISP is under Maxis.
If you want Public IP, you call Astro customer service, then Astro escalates your request to Maxis.

Astro Fibre however, is Astro's own Internet service, and does not rely on Maxis at all.
You'll be getting Astro branded router, and it uses Astro's own VLAN ID, not Maxis VLAN 621.
If you do speedtest or check the IP address, you'll see that your ISP is under Astro Fibre.
If you ask for Public IP or VoIP, then they can only say sorry to you.

The thing that boggles my mind was, why this is happening right on the dot 8.30PM until about 11:30pm every night.... Its feel like its a schedule throttling, some kind of network shapping by astro fibre to my connection....if there's device or equipment or hardware problem, why other than the time period that i mention above, i dont have these problem, everything works fast and smoothly....

What do you guys think actually happen...?

Thinking going to TM as i got a feeling that astro dont have the capacity to deliver what they promised...

@joshhd

I use your post earlyer to ask for Public IP for RM5.00 per month

But i think,  i got fixed IP instead, not public ip....why i say this because when ever i restart my router my ip was always the same, how even when i check with whatsmyip website, clearly the ip it show is different from my router internet ip, which suggest its not a public ip right....

When i restart my router, yes the ip stay the same. The whatsmyip website also stay the same, although its stay the same but its different from my router IP vs the website IP...

So what do you guys think? Izzit public ip or still private ip with fix ip number

So the question really do Astro Fibre have Public IP option, their agent also seems confuse with the term private Public and Fixed ip..
