So for the past month I get this briefly when I try to go online on my note 20 U. It's brief like so brief I had a hard time getting a screen shot of it. It's basically always saying no wifi, but then it connects. It's just this brief message everytime. My wifi is great. Many other devices in the house and no issues with any of them. I've tried repeatedly to reset my modem etc and a few other things but really it seems that my phone is the only device having this issue. Is there like an antenna in this phone? Could it be going bad? Any suggestions? See attached this is what I get. After getting this it does connect without problems. Thanks in advance for any help.
