5Ghz WiFi has the bad habit to not go well through walls and objects in between. Hence it is usually suitable when you have a free line of sight between the AP and the user device.
2.4Ghz is way better at going around corners and through thick walls (even though it has some limitation. The 50cm walls in my Summer Mansion will let only very light 2.4Ghz go through, and no 5Ghz at all).
I tend to link all my fixed media devices using 1Gbps ethernet. All āmobileā devices can then āfightā for the available bandwidth.
Oh, and one last thing regarding the WiFi in general. A switch is capable of separating traffic going through specific ports so they donāt disturb each others traffic flow. An old HUB repeated all data to all ports. So does WiFi. Wifi is to be considered a Broadcast domain. Means all actively talking devices will share the common slowest wifi speed to communicate. In other words, if you have 5 active devices on your Wifi, you can divide the total bandwidth available to each device by 4. So if you have a kid in a āfarā away bedroom watching a Youtube video (continuous data flow), all communication will drop to the speed of his connection (More or less. Depending on the number of antennas your AP has etc. it may optimize it all, but I assume here we have one antenna only for simplicity). It may change speeds if your kids device stops requesting data for the others, but the speed changes take place in about 76microseconds. So if there are very many speed changes, it can be counter productive.
PS: I have 4 kidsā¦ Took me a while to figure out that the very old 2Ghz devices of the kids were slowing down the entire WiFi experience of the house
Yeah I try to keep everything on wired, but where this TV is ive no real way to get a ethernet cable to it other than have it on show and go over doors as its solid concrete floor, the 2.4g AP is about 5meters away on this SSID through 1 wooden floor
@sam_nazarko It did same again logs show it couldnt connect to TVHeadend for ages.
Would tunring on debug mode, show why the wifi is disconnecting or becoming unusable?
Its quite sparadic, some times days before it happens, yesterday was in 2 hours
other than buying some ethernet over powerline, dont know how else to diagnose
Have you tried using a couple of Powerline adapters that have ethernet ports ? the latest generations are fast and reliable. I have one next to my router and one behind the TV, gives me 3 ethernet ports and 2g/5g wifi, keeps a Roku, Switch, RPi, a couple of phones/tablets and a Samsung tv and going no problem.
