IPv6 Enabled But Doesn't Work?

[alap4m]

Firstly, MANY Thanks for this Forum.

Following multiple tutorials, I have enabled IPv6 in the Syrotech Combo device. Its interface confirms IPv6:
BSNL Fiber FTTH IPv6

The OpenWrt router connected to this Syrotech Combo Device gets IPv6 too:
OpenWrt v23.05

However, none of the devices connected wirelessly to the OpenWrt Router have IPv6 addresses or IPv6 Connectivity:
Windows 10 v22H2 (Wi-Fi 5Ghz)

Please advise how to activate IPv6 Connectivity.

[Update 01]
IPv6 has been configured correctly on Windows PC and it works, BUT ONLY for Mobile Hotspot:

This means IPv6 is configured correctly and works with Cellular Data.

However, while using BSNL Fiber FTTH, it shows IPv6 "No Network Access."
Hence, IPv6 is showing only till OpenWrt Router. It is not being passed downwards to connected devices.
What could be the issue?

@alap4m It looks like you are facing same issue as i've been facing while connecting through Wi-Fi to get IPv6

Just do this modification in your settings and it will start working.

Press on Properties -> Internet Protocol Version 6 -> Enable it -> done.

This will fix your issue. By-Default, it got disabled by Windows

Did it fix your issue @alap4m ?

Mine's enabled in Windows and I do get the v6 address but it shows No internet access over IPv6.

Pinging to any IPv6 site fails.

In my case, BSNL does not provide IPv6 in Maharashtra. Are you sure your location has IPv6 enabled ?

@!!..PD..!! You can see clearly from his SS that he's receiving the IPv6 address.

This is my IPv6 enabled just like him so it should be working for him too.

@Protector His screenshots are not visible to me. It shows Image not found or removed.

Also, I get the IPv6 address and DNS on my ONT and Router but No internet over IPv6 and IPv6 test fails (Laptop as well as Smartphone) Wired/Wireless does not matter.

 

[Protector]

Do you only got DNS or DNS with IP Address? Either way, Screenshot will look like mine and if it is like that, Try to connect yor Laptop with Ethernet and see if IPv6 is enabled or not in Ethernet & Internet connectivity Properties.

 

[!!..PD..!!]

Its enabled.

Also, I get the same as you in ONT (Including a blank dns2) when I tried it through the ONT.

Now ONT is in bridge and I've configured IPv6 through router and its the same. I get address but Internet doesn't work over V6

Sorry for the late response.
IPv6 is Enabled in Adapter Settings and it works But ONLY for Mobile Hotspot:

Hence, IPv6 is only showing Until OpenWrt Router, but it is not being passed downwards to connected devices.

@alap4m , Can you ping ipv6.google.com from your router ?

If not then configuration issue. If configured correctly then issue like mine. I get address but no internet.

@alap4m I can't see the screenshot because they are removed. Is ONT in bridge mode and Openwrt runs PPPoE? On PC nothing needs to be done as IPv6 is enabled by default.

@!!..PD..!! Which device do you use, ONT or a separate router?
