Question Wireless connected no internet please read

[bobbart]

Hello,
I know that I could find so many posts all over the internet about this subject however non fit my issue.

I am having interment-ed issues with connected but no internet on my wireless devices. (phones, tablets, fire sticks, smart tvs and other smart devices)
I do not have issues with WIRED devices!!
I have done the following to trouble shoot.

1. Reboot, Factory Reset, Changed Channels ect on my Default Cable Modem with WIFI.
2. Purchased a top of the line WIFI router, turning off the Cable Modem WIFI
3. I setup a WIFI extender
4. I setup an AP

All with the same results. What am I doing wrong? I did not have this issue for years then suddenly POOF
The only thing I can think of is I have some kind of interference that has moved into the area.
NOTE: I am in a very rural area

Make and model of your wireless router? Often times it's an indication of a wireless router failing or on it's way out. On other circumstances it can be possible that your neighbor or other appliances in your house are conflicting.

Have you checked to see if a firmware update is pending for your router?

Its a new cable modem router, it cant be a failing wifi router since I did try 2 others

Whats the note on my post about a Tone?

The strange thing is that my s9 may work just fine atm, BUT my Samsung Tablet is getting no internet on the same WIFI connection. Then my S9 may show no internet but the Tablet is just fine. This happens across many devices in the house.
Its not that I have too many devices, its not that I have no IPs available in the DHCP

You still havent told us about your setup. Make and model of it all would be nice.

There's a cable entering your home, copper or fiber, which goes into a modem. Are you using that as a router?
