Hi @flavius75,

I recommend you try restarting the TV when you encounter the problem. You can find instructions on how to properly power cycle your TV (soft reset) on this article.

~~Also note that generally it is better to leave the 5.0 GHz Channel setting on the TV to Auto, unless you are having difficulties. Then of course set a predefined manual channel number.~~

Cheers,

Dutchice

Edited: The option for setting a manual channel for the 2.4GHz and 5.0GHz band is only provided for Wi-Fi Direct connections to the TV.

Hi @flavius75,

~~Both your TV and router must be set manually to the same 5.0 GHz channel.~~ Most often routers are set by default to auto select channels. This causes them to hop from channel to channel. Which is in theory desirable when encountering interference from other routers in the neighbourhood, but in situations like yours, might cause problems.

I recommend you invest in a pair of basic Powerline adapters. Any option with at least 200 mbps of data speed should be enough for your TV.

Cheers,

If with a new Router and Provider the connection is maintained for at least 2 days you could try to change the Wi-Fi Channel by choosing a less crowded one...

Hi @flavius75,

The option for setting a manual channel for the 5.0GHz band is only provided for Wi-Fi Direct connections to the TV. Wi-Fi Direct connections are used for content sharing or screen mirroring purposes only. So my apologies for suggesting you could set that manually for your TV wireless connection. I have corrected my previous post already.

If using the wireless connection of your TV is proving not to be reliable, there is only one silver bullet remedy for it; and that is as I suggested earlier to invest in a pair of basic Powerline adapters. Any option with at least 200 mbps of data speed should be enough for your TV.

Cheers,

@flavius75: I forgot to mention that if you still decide to give the wireless connection one last try before giving it all up, you could read this article which explains a number of areas to look at regarding poor wireless connections.

I had already tried all the solutions in the recommended article. Already becomes a bit frustrating, as long as absolutely any other device connects to 5g, including a smart tv samsung, regardless of the distance to the router. At one point, the sound completely disappeared, but it resolved with power reset.

A power line system is not efficient in my case, due to quite somewhat branched electric paths. A test led to a significant loss of speed.

The only solution is to mount a switch from which to connect sony tv and nvidia shield (there is only one internet cable pulled in the area).

The Android system on TV Sony seems to be a disaster at the moment (it does not compare to the Android on the nvidia shield).
