Soundbar S61B and QN90BA 65 WiFi bandwidth not the same

[Rednaxela1972]

Hi, when setting up the Soundbar, the TV finds it no problem and everything works great.

however, the next time I turn the TV on, it defaults back to just the TV speakers, not symphony. When I try to connect, the tv says “The wireless bandwidth of your tv and wifi speakers is not the same, select auto set to match the bandwidth of the wifi speakers to the Tv”

when I click auto set, it just hangs for half a minute and gives up.
The only way to resolve it is to hard reset the Soundbar every time I want to watch tv. 
my router is a BT with two discs. I believe the tv is using 5Ghz and the speaker is switching to 2.4Ghz.

does anyone know of a way to fix the issue?

best regards Alex.

I had this the only way to sort for me was to connect HDMI to soundbar & tv

I am facing similar issues connecting Samsung Freestyle with Q70R soundbar over wifi. It worked perfectly for few days, I changed the location of both devices going away from Wi-Fi router, and started facing this. Trying to resolve it, will share my experience.

I resolved it by using a different SSID for 5Gh signals of my router. Earlier, my Samsung freestyle projector was randomly picking up the band due to same SSID of 2.4 and 5Gh bands. By changing SSID, I can choose which band my projector connects to. Soundbar has option only to connect to 2.4gh band, that’s why I have to choose same band for the projector too.

Hi everyone! For those of you encountering the error described — “The wireless bandwidth of your TV and WIFI speakers is not the same”, please be informed that this is caused by the fact that the TV and the Soundbar are using different Wireless radios/frequencies/bands — by default the TV is connecting on 5GHz, while the Soundbar only supports and connects to the 2.4GHz radio. This can be fixed either by connecting your TV to the normal WIFI network (the 2.4GHz, not 5GHz) - modern routers have 2 different wireless networks by default , or, in case you have a router that has the same network (SSID - Service Set Identifier) for both frequencies/radios/bands, you can enforce a filtering rule for the TV based on its MAC (you can find the MAC simply by accessing the Main Menu, going to Support section, and then About This TV, and scrolling until the MAC is listed) in your router WIFI configuration.

This works irrespective of TV and Soundbar models.

I hope this makes your life easier, I lost some time on a Saturday evening to solve this, instead of enjoying a beer watching a movie. Cheers!
