Stock router most likely has CWMP or TR-069 that basically sends info back to isp and also allows remote changing settings or upgrading firmware

If 3rd party router, and you don't set it up (why would you?) then the ISP has no control over it

With the said the modem probably also has it too.

Don't bother getting the mesh wifi through them
Just buy your own mesh router (DECO M4 or M5 is good) and set it up by yourself.

Depending on your needs you probably only need 30 to 100Mbps

Also, if you do get your own mesh router, DO NOT follow TM's instructions of plugging the mesh router into your stock router, then setting up with dynamic ip. This creates a double NAT and conflicting wifi's, terrible instructions.

Instead, ask customer support for your PPPoE credentials, then set up one of the mesh nodes in PPPoE mode.

Note, if you do use the unifi TV Box there might need to be more settings set

But you can find many tutorials online telling you how to, such as https://youtu.be/TOFEVnjbBDc

Depending on which ONT you have, you might be able to plug an ethernet cable in and login to the modem's webpage and read the reading, it should be less than 28 at maximum, ideally less than 25 or more for a stable signal

If it's high that means TM used a bunch of splitters to get more ports of out of 1 box

Just tested, blocked on U Mobile too, changing dns works (using DoH)

Maybe cause U Mobile peers with TM?

Edit: just did some tests with traceroute

With U Mobile DNS
It goes from 1.9.247.157 ™ to 175.139.142.25 ™ and just ends there being blocked.

Where as with any public dns resolver
It goes from 1.9.247.157 ™ to 104.16.110.36 (Cloudflare) and the site works.

Either IPv6 DNS was left unchanged so it's leaking there
Or
Their system remotely pushed settings which reset your dns settings.

They could have done a cheap tatic of using a splitter which gives them more ports but could have degraded the signal to the point of being too weak for you 2

If you get a contractor in your house, ask them to show the dBm reading of the fibre line, should be around 18 to 23 or so, 25 being kinda weak and 28 and up being unacceptable

I'm unsure if there's a preset VLAN profile but in case you need to set manually Unifi uses VLAN ID 500 for internet and VLAN ID 600 for HyppTV (ircc)

I would suggest removing the stock router and using only the deco as the router + mesh.

I don't know why but Unifi's default instructions for mesh is to connect it to the stock router and broadcast yet another wifi that will compete with your stock router (they literally tell you to forget the stock router wifi, doesn't even tell you to disable it) while also creating a double NAT

The better way is to just remove the stock router, and make one of the Deco nodes a router. More control, less back doors.

Maybe the other contact is the one having network issues?
Try another video calling app

From what I've seen on this thread older installations seem to get a tplink or a dlink, new ones are a very generic branded white box router (Aztech)

Just use your own router, it will be better

Well just note that whatever name you set as your wifi name you'll end up promoting for them
their stock firmware always adds @unifi to the end of your wifi name

Does IPv6 really make that big of a diffrence?
I disabled it because I use Maxis because the older Archer c5v stock router you can't change IPv6 DNS which causes a DNS leak for Pi Hole

Did they like try to block some site, did just a bit of probing, got some IPs, didn't even check who's it is and just blocked Cloudflare in the process instead of the actual site?

Ah I see, I use Maxis and use a public dns provider so I never see these problems lol.

Also, I did a look up on that IP, and I can see why TM tried to block it, but they didn't realize other stuff is hosted on the same IP too

I think it's the signal strength or something of the fibre cable
It should be no more than - 28dBm

to add on to this, it's the PPPoE username and password

otherwise nanti maybe they give router login details lol

Most ISP's cut cost and just give the cheapest thing that works okay-ish
Like, if you signed up for 800Mbps, I doubt you'll ever see that on the stock router.

TP-Link Tether app

Im on Maxis Fibre, what do you want to test?
