I've noticed that after I updated my galaxy S10+ to the new One Ui 2.5 my WIFI connection doesn't work as smooth as before.
Although it shows full signal the internet it's slow, youtube loads slowly, and even whatsapp and other messaging app,I sent a message but the message didn't sent quickly, though the wireless connection was on and with full signal. Same thing working properly with Mobile Data.
My internet connection is 150Mbytes/s so it's not the network. With other phones my wireless connection works smoothly, but with samsung S10+ after this update it looks like it keeps disconnecting. I've tried wipe cache but it didn't help.
it may not be your phone. maybe the fiber connection is weak. have you tried contacting your LCO? connect your pc to the wired internet and check the ping, upspeed, downspeed there. I am on OneUI 2.5 as well. internet is working perfectly fine for me. reset your router if you can.
@schoolboy26 Yes I checked all those thing and restart router as well. And I also checked with another my android mobile and it's working properly over there with same internet and router
