Unable to block internet access to a client: RT-AC1900U / RT-AC68U

[webbie]

Hello!

I have just bought an asus AC1900U to substitute my provider router (Moivistar, triple VLAN config).
I'm very happy with it. Amazing wifi reach and speed, and I love the UI. And configured very easily.

I only have one problem that I can't understand.

From clients (either in 192.168.1.1 web access or Asus app), I try to block internet access to one client (a cellphone or a smart tv for example).

I slide the control (Block internet access), click apply, but nothing happens. It appears an earth globe with a red nope sign across, but all devices can merrily access internet as nothing happens (I test it with wifi).

I have tried hundreds of times with no success. Even after a reboot.

Am I missing something? I've read across internet and it seems that this enough to block a client. No other setting needed. But maybe there is an extra setting to get it.

Now, some information about versions.

My asus router asked for update and get the 3.0.0.4.384_45713 version.
After the update I performed a hard reset and full reconfiguration (wps button on, power on some seconds)

I realize that there are newer versions: https://www.asus.com/Networking/RT-AC1900U/HelpDesk_BIOS/

But reading all changelogs between this version and mine, there is nothing related to this issue. So I am sceptical that it can fix it.

My approach to updates is that I only upgrade if there it sure to fix something I need. If everything is ok I don't update. I have suffered a lot bad updates in a lot of devices (not Asus but in general). Fix one thing, break two and also bigger. And then you wish you never did.

A last thing. I realize that AC1900U is exactly the same as a Rt68U:
https://www.snbforums.com/threads/rt-ac68u-rt-ac68p-rt-ac1900-rt-ac1900p.35759/

And also all FW files in asus web are exactly the same MD5 for both Ac1900U and Ac68U.

I point out this just in case a RT68U can share its experience since RT1900u seems to be less popular and extended...

Thanks a lot!

Ops.

There was some extra info in the asus firmware section.
And a later version has:

- Fixed block internet access problem when clients connected to AiMesh node

I am not using aimesh but probably this is the issue...

I'll try then...

Thanks!

They are the same, only different naming. Even an RT-AC66U_B1 ist same hardware in 66U housing.
Updates are for security reasons too, not only for fixing bugs.
You should try Merlin firmware! It may solve your issues.

I can confirm it is a fw issue. It is fixed with the update.
Thanks!
