Thank you for the information. The M5 has the browser login, but the M9 does not yet.

In any case, we will look into this for you to see what we could find.

@rookie7799 

When the phones start to have the error mentioned, do they have and IP address?

Please also install iNetTools, select "DNS Lookup", put www.google.com and grab a screenshot of the result.

In the same app select trace router, put www.google.com, and rab a screenshot of the results.

You can direct message the screenshots or send an email to: ussupportteam@tp-link.com let me know which was done.

@Tony inettools is not available for Android.

@rookie7799 

Grab "Network Analyzer" https://play.google.com/store/apps/details?id=net.techet.netanalyzerlite.an&hl=en_US

DNS and Route is what would be used.

@Tony 

None of those work at all when I get those connection issues, see screenshots.

Please check your direct messages.

@rookie7799 Did u ever find a fix to your occasional no internet?

My brand new samsung s10 keeps getting "no internet available". Shutting wifi on and off resolves the issue but that is not what I expect from two brand new items (deco and s10).

 

Both 5g and 2g are on.

Latest firmware.

Deco m9 plus + deco m5

 

Any suggestions?

Did u ever find a fix for this?

Only just saw this, after posting a similar problem.

I need to try playing around with 5G wifi as well to see if it impacts the issue.  Weill post back with results in a few days time.

I have the same issue with TP Link X20 and S10. Seems that when the phone picks up signal from 2 APs at the same time, it has periodic trouble and takes up to 10 seconds to figure it out. Other devices don't have this problem
