Just got a lg sk6y sound bar with wireless sub. Installed it then all of a sudden Wi-Fi in lounge area is crap. On slingshot gigibit with there router. Then I turn off sound bar and wifi back to normal. Any suggestions or recommendations?

Change the channel you're on. I get lots of warnings from my unifi gear about interference on channel 11 when I use my LG soundbar. Put them onto ch 1 and the warnings stopped. Its just the 2.4Ghz wifi and everything still works with it on, just slower, since its 2.4GHz I dont really care since the stuff that matters is all using 5GHz.

The sound bar is not connected to any wifi tho. For example start a Speedtest turn off sound bar then speed goes right up. I thought connection between sub and sound bar might be interfering with it. Everything I use in my house uses 5ghz

Can i ask a dumb question if everything in your house uses 5Ghz, can you turn off the 2.4Ghz on your router assuming its dual band? would that make a difference, i mean logically it shouldn't as the sub isn't attached to the router, but stranger things have happened

There's a host of things that could be at play -

1: Chromecast can spam the network when it's not connected, try connecting it to your local network.

I've seen it cause havoc... but a very easy fix.

2: The wireless sub may be connecting over WiFi and not bluetooth, which may be causing issues, the same can be said for the 'wireless rear speaker' capability. Try turning both of these options off and see if that fixes your issue.

3: It's an LG product with Google Home built in, it's probably busy stealing your information and taking up all your bandwidth to do so... just saying... ;-)

That's interesting, I have had some 5Ghz performance issues of late, and I have an LG SJ-5 with wireless sub located quite close to the mesh point. Interesting, I used to have the sub on the other side of the room, might move it back there to test and see what happens. You're right, the sub and Wi-Fi technically shouldn't interfere with each other on 5Ghz, but who knows what's happening.

The sub might be using the same bands as your WiFi for its wireless interface, but using a protocol that is completely different to WiFi. Therefore causing lots of interference.

Try changing your WiFi channel as suggested above. Otherwise get a wired sub.

The frequency bands used by WiFi are general use bands. Meaning that they are also used by lots of non WiFi devices.

@fprfalcon Well there you go. I'll move it back behind the couch and see how we go. Is this mentioned in your manual too?

1m is the point where it will start to be desensitized by the other transmissions overloading it, not it starting to be a problem for other things. 5m is still plenty of range to have other things be affected if its on an overlapping or adjacent channel.

Spec sheet lists 2.4 and 5Ghz channels are used. Doesn't say much more than that.
I would say it is the sub causing the interference. It only needs to be in the same broadcasting range and area as one other device to interfere.

Many wireless subwoofer senders don't comply with the 802.11 standard... instead they broadcast across all channels in order to 'get their signal through'.

Good for them, terrible for anything else in the room / house that works on WiFi.

Bluetooth subwoofer connectivity lacks in range, but causes far less havoc than many other products. UNLESS the brand is open and obvious re: how they connect, then diagnosing network issues caused by wireless rears / subs is a giant pain the buttox.

As an example, Sonos allows you to set the SonosNet to a specific channel (1,6 or 11 etc) - and their wireless rears and sub only connect on /n and not a/b or g in the 2.4ghz spectrum.
