What do you mean "video picture tends to be glitch on 2160P"?
You mean, you see pixelation only when you're watching Astro UHD channel 780, am I right?

Now you try go to channel 780, then press home>Settings>Satellite Settings>Diagnostics
Then, now press right arrow button on your remote control, which it'll scrolls right to Tuner 2.
Here, take a photo of it and show the signal reading page here.

Hmmm...
Try Restore Factory Settings on your Ultra Box, and try use other HDMI cable if you have.
If issue persists, then the technician might have to come over and check to find out what happen...

Contact Astro Customer service for further assistance.

Have you done speed test when this happened?

The speed is not the problem.

Wait. The low speed will not pixelate the picture but stuttering it 

Whether pixelation is common or not has nothing to do with satellite or IPTV. Service providers operate on available bandwidth they paid for. They will try to maximize the available bandwidth. In order to put more channel they have to reduce aux (just term I created for necessary but not absolute must) bandwidth. Each data frame consisted of error correction code (ECC). The receiving device will made correction to corrupt data based on ECC. Transmission implement FEC (Forward Error Correction) where data is encoded to create data redundancy.

In order to get more bandwidth, the ECC is reduced, thus the transmitted data will be more prone to error. So, corrupted data in transmission due to noise in transmission will less likely be able to be corrected. So, picture pixelated.

I think Astro is squeezing as much as possible from bandwidth right now since they need to introduce more HD channels. 

oops are u sure 300mbps u get 250-300? Unifi hardly passes 200mbps man!

Used to be using Astro IPTV (PVR box),, pixelation issue did happen since few months ago(while I was using Astro IPTV)... even Microsoft Teams video call is pixelated for some reason... downgraded back to DTH and switched to another ISP,, problem disappears(and adds a new feature: the rain detector service)

Astro IPTV uses a dedicated bandwidth(for live TV), not the same as your internet speed

Sounds like an issue with astro side,, didn't bother calling astro IPTV CS when I had this issue since was planing to switch ISP at that time already

You can also try speed test at https://fast.com/

chuah_phYeah, since you sent the email to wecare, give them about few days time to let the technicians do the checking, especially in the network part.
But no matter what, you have to follow up with them ya. Don't just leave it "unattended".

If worse to worse, if they don't take your matter seriously, just threaten them politely to terminate their service (either via call or email, or whatsoever).
Yes, there is 24 months contract, but the thing is, they are providing you an unsatisfactory service and they seems like they don't want to solve it as soon as possible.
Or, ask for some sort of compensation, such as prorated bill rebate during the number of days/weeks that you face the same issue.

Or, you may exercise your rights as a consumer by filing a complaint to MCMC here: https://aduan.skmm.gov.my/

Sometimes, a company would only take customer's complaints seriously when the customer threaten to terminate its service, cuz matters like this, will alert their customer retention team.

Do that only when things turn ugly la... As simple as that. 

I personally believe it is not on your hardware side. Technician came during day time but pixelation is at night, right? 

Probably network congestion in your area at night. 

Yes, public network I meant. Too many people creating too much traffic in your area hub probably

I just tried briefly the 780 and it looks fine. Tried the 4k movie collection in Movie and I can forward and rewind smoothly last night ..

Pretty much any routers (doesn't matter from TP-Link, D-Link, Asus....) that supports VLAN Tagging will be able to support IPTV function for Astro IPTV or even TM's Unifi TV.
You might need to configure the router settings (especially VLAN Tagging settings) by yourself for it to work.

That one I'm not sure. Any Astro IPTV users here can share further?

And yes, the VLAN ID:
Maxis IPTV is 823,
Maxis Internet is 621

If your WiFi router is placed on your house's ground floor, try put it somewhere higher from ground, like on top of a cupboard or shelf or something.
Otherwise, consider 3rd party router as AP, or use mesh WiFi.

For maxis infra

Internet :11
IPTV :17

Do keep in mind that VOD will not work with 3rd party router since it’s somehow maxis merge both of the vlan on maxis router(not standard with 3rd party consumer router at least), this also mean that the Ultra box will operate as a “HD Decoder” on Astro IPTV with 3rd party router( assuming they didn’t change anything from astro PVR box)

Unifi doesn’t merge both internet and IPTV vlan on their router,, their IPTV setup is the same as 3rd party router(dedicated lan port for IPTV)
Yup,, only maxis router as far as I know can do both at the same time

Recent ditched Astro IPTV few months ago since their service isn’t reliable at all during mco
