The WiFi keeps disconnecting.
I recently got a Samsung DU8000 & a Roku Streaming Stick 4K.
The 1st time that I tried to install the Roku software, it kept stalling. I tried several times to restart it. Each time that I restarted the install, it got a little further.
I don't have any problem accessing the internet with my new TV. My printer connects wirelessly to my computer with no problem.
According to the directions that came with the box, the TV needs to be set on the HDMI port into which the Roku is plugged. I didn't do that the 1st time. I turned on the TV & set it to the Roku port. I did a factory reset. Unlike the 1st attempt, I was able to install the software. I had minor problems. When the install was complete, Roku stated the some software wasn't downloaded so it redownloaded Netflix. I didn't have any problems navigating the Roku app. But when I tried to open an app, Roku stated that the app couldn't be downloaded because there was no internet connection. I don't understand why there was no problem with the internet while the software was downloading, but when I tried to open an app, the internet was disconnected. I reset the player. Roku scanned for wireless routers. I successfully entered the SSID & password several times. It started to connect but failed. It's almost as if the Roku doesn't like me & is being mean to me but I know that isn't the case.
The TV is mounted to the wall so it's hard to access the stick. I specifically ordered the stick with the amplifier because of the distance from the stick to the router. I even had the router unplugged & rebooted. It didn't help at all. The cable is also bunched up behind the TV. The instructions recommend not bunching up the cable. I wonder if replacing the ("amplifier"?) would help. I have a USB-A to USB-C cable. I can switch out the amplifier cable with the USB-A to USB-C cable & see if that helps.The router is 30 feet or more from the stick. The router is a few years old. The distance & the age of the router may be what's causing the problem.
I can't think of anything else to try. Can you?
