HP AX2 wireless and Samsung TV

RouterOS Wireless Networking
1

Hello, I recently bought a new Mikrotik AX2 router, I configured, but and I tried almost all the variation I could think on WIFI but it is not connecting to my Samsung TV 2024 model.
I can connect from my laptop, from my iPhone but not from TV. My TV see both wireless networks but after I add the passkey it says: media disconnected, or something like this. For now I connected to TV to the internet by using a cable. Is there anything I can do to connect it via WIFI ? Is there a way to downgrade to WIFI 5?

Let me know please if you need more details. Thank you very much.

Regards,
Bogdan Claudiu

What security settings are you using ?
Quite a bit of IoT devices (and that includes quite a bit of SMART TVs) only accept WPA2 and nothing else.

Hello, I use WPA2 and WPA3 now, but I tried each one individualy WPA, WPA2 and WPA3 only checked.

I’ve had a similar problem with a generic Android TV box. My main Wi-Fi is normally configured with WPA2 PSK and WPA3 PSK. Even though this TV box can use WPA2 PSK, it will not connect. So at the moment, I’ve got a secondary virtual network with just WPA PSK and that works fine. I’ve got a reminder to revisit this because I’d sure even if I set the main network to WPA PSK and WPA2 PSK, it still didn’t work, i,e, in the networks below, it won’t connect to Shire either.

The Android TV Box is relatively new, running Android 13 so I’m a bit surprised it can’t connect when WPA2 PSK and WPA3 PSK is defined on the interface. Hence the reminder to revisit.

And no encryption cyphers selected ?

Can you export wifi part of config ? (leave out passwd etc).
It will show there.

I have just bought my hAP ax2 less than a month. I updated the RouterOS 7 firmware to 7.16.2 (the latest release) and I’ve been also facing the same situation with a brand new 85" Samsung SmartTV QA85Q65DAKXXT. This Samsung could connect to my Iphone Personal Wifi Hotspot without any issue. It can also connect to hAP ax2 via WPS. But it would not connect by default factory “AP” mode Wifi on this hAP ax2 at all. For those who successullfy connect your Samsung TV to your Router OS wifi. Could you please share your Wifi Authrntication settings? So that I can follow.

Was this directed at me?

There was nothing in between your post and mine, so that would make it directed to you, yes.

I operate a WISP and have been supplying hAP ax2 to my customers as a managed router.
I have encountered issues at multiple households with Samsung TVs and it seems to affect hAP ax3 also.

The TV will see the network but is unable to connect. Logs on the router show no sign of any connection attempt.
Disabling WPA3 or PMKID or 802.11ax doesn’t help. The same TVs will connect fine to a hAP ac2 or a TP-Link WiFi 6 device.
Various RouterOS versions have been tested from ~7.10 through 7.17rc3 with no success.

I have only seen this issue with Samsung TVs, but not all models.

I managed to solve the issue by switching from the default “2G ax” to “2G n”. This SSID has no 5G enabled. I’ll later extract the full WIFI config to show here.

Yes, I tried that as well and it indeed “fixes” it. It’s the presence of the Wi-Fi 6/AX protocol that appear to be the problem. This isn’t restricted to Mikrotik. I’ve read similar problems with other manufacturers. Dim memory that older drivers assumed certain bits/values in the packets. A completely made up example: there was a byte in the header in Wi-Fi 5 where only four bits was used. The rest we’re unused but typically set to zero. Bad code written that assumed these four bits were zero. In Wi-Fi 6, these bits were used and therefore non-zero. The bad code chocked on them.

From memory, I don’t think you can have AX as the master interface and N as the slave? For obvious reasons - the radios use one protocol or the other. You can have 2.4GHz with N and 5GHz with AX as they’re different radios.

Disable WPA3 and Use WPA2-PSK Only: The Samsung 2024 TV might not fully support WPA3, which is enabled by default on the AX2. In the RouterOS interface, go to /interface wifi security, select your security profile, and set authentication-types to wpa2-psk only. Disable wpa3-psk and ft (Fast BSS Transition). Save and reconnect the TV.
Force WiFi 5 (802.11ac): To downgrade to WiFi 5, go to /interface wifi, select the 5GHz interface (e.g., wifi1), and set channel.band=5ghz-ac instead of 5ghz-ax. You can also try setting channel.width=20mhz or 20/40mhz to improve compatibility, as some TVs struggle with wider channels like 80MHz.
Check Firmware: Ensure your AX2 is running a stable RouterOS version. Many users report fewer issues with 7.8 or 7.14.3 compared to newer versions like 7.15 or above. You can downgrade via the RouterOS interface or Winbox by uploading the appropriate firmware package (e.g., routeros-7.8.npk and wifi-qcom-7.8.npk) from Mikrotik’s website, then issuing /system package downgrade. Reboot after downgrading.

If someone helps. Also migrated from ac2 to ax2..
Got work Samsung S90F Smart TV (2025) ( WIFI 5 ).
But it is hard to test settings.
I always did this steps:

  1. Disable/enable routeros wifi interface.
  2. Reset network on TV. (because sometimes it save some old settings.

exported wifi interfaces:

#2026-04-28 23:08:49 by RouterOS 7.22.2
# 
# model = C52iG-5HaxD2HaxD

/interface wifi
set \[ find default-name=wifi1 \] channel.band=5ghz-ax .skip-dfs-channels=
10min-cac .width=20/40/80mhz configuration.mode=ap .ssid=xxxxxxxx-5G

.ft-over-ds=no
set \[ find default-name=wifi2 \] channel.band=2ghz-ax .skip-dfs-channels=
10min-cac .width=20/40mhz configuration.mode=ap .ssid=xxxxxxxx disabled=

From wifi registration: samung tv:

1 A wifi1  xxxxx-5G  80:0D:3F:XX:XX:XX  8m58s  0ms  -61 wpa3-psk 5ghz-ac

From wifi status: current 5 ghz channel 5680/ax/eCee/D. Don't know it matter something or not..
