SAMSUNG TV wifi connection

Spajda · Fri Dec 25, 2015 11:50 am

Hi,

I have different situation with my samsung smart tv.
Its brand new one 32", and latest software installed.

I have also mikrotik RB433 with v6.19 os

From 2 months i cannot connect samsung tv and my wifi module (2,4 Ghz).
Previously this setup has working fine, and i have no problems at all.

Something changes (i cannot confirm what it was), and my Samsung TV cannot connect via WiFi to my network.
When i use wired connection, everything is OK, so its not Samsung fault.

Today i use my phone (galaxy S6) to create mobile network, and Samsung TV connect to it and i can browse network perfectly.

So only reasonable answer is my WiFi settings are wrong, and that why i cannot connect my TV to Mikrotik network.

Can you guys help me with setup wifi network to allow my TV to connect ?

1. When i connect tv to wifi there is no response in logs
2. I tryed to change channels from 1 to 11, nothing helps.
3. security profile change to open also not helps
4. Other devices (androids, iphones, ipads, laptops etc working fine).

I`m not a mikrotik pro.

I presume you have tested the same WiFi SSID with other devices and it works OK? And you use WPA2-PSK?
Please use "/interface/wireless/export" in a terminal window and cut/paste the result here.
(DO NOT make screenshots of winbox windows etc)

Hello,
Yes, other devices work fine (PC, 6 different android phones).
Yes, i use default security profile (wpa2-psk).

Ok, I see that you have profiles with authentication-types=wpa2-psk,wpa2-eap (both PSK and EAP in a single profile) and that is usually problematic, but it looks like you are not using those.
The settings look OK to me, almost everything is at default.
You could try to temporarily add a profile with mode "none" (open) and check if it can connect then, to see if it is an authentication issue or something entirely different.

Could it be that RouterOS picks a channel that's not supported by the TV? Might happen if you have an international version of Mikrotik and other devices but some regional restricted TV. Have you tried separate SSID from 2.4 and 5 networks to force Samsung TV on 2.4? Have you tried changing channel width (e.g. to 40Mhz only) on the 5 network?
