I have two s9 phones both over last few days since a samsung update on 8th April are coming up an exclamation mark when connecting to my wifi saying internet not available. This happens when it switches between my 2g and 5g ssids. The phones are indeed connected to my wifi as when turning off mobile data and connected to wifi I still get web pages. Although with this error can't download from Google play or connect to anything on my lan.
The issue goes away if I turn off 5g ssid on my router not ideal!! Router has latest firmware and all other devices connect fine as well as an old htc m8 phone no issues only on two s9 phones do I get this anyone any ideas.same issue here although on s8 https://www.google.com/url?sa=t&source=web&rct=j&url=https://forum.xda-developers.com/galaxy-s8/help...
Thanks you so much. My mom used the wifi on an interstate bus, wich had wifi connection. That changed rhe private DNS to a fixed value. By changing it back to auto did the trick.
I've noticed when using the wifi analyzer app that when I turn off my wifi, it can detect 5ghz networks. However all 5ghz disappears as soon as I turn on the wifi on my phone. Anyone else notice this?
This is extremely annoying. My iPhone 6s gets 145mbps down and 150mbps up but my S9+ gets 50 down and 50 up.
