Hi  @bmwridr 

 

Welcome to the community!

 

What brand/model thermostat are you using?

 

Have you tried changing the router's DNS settings to see if the issue is DNS-related? Steps on how to change DNS can be found in this FAQ: How to change DNS Servers on TP-Link Routers

Some devices require that bluetooth be turned on to make the initial connection. May need to power cycle both the device and the phone/tablet/pc

ive tried all that a week ago. tried every trouble shooting option on sensi website.

 

if router connect without internet it has to be something simple. im to the point that i just buy a new thermostat but the interface and app have been awesome with zero service issues the 3 yrs ive had it until now trying to connect to this new router

When a device has been connected to another router and will not connect to the new router, even if the ssid and password is the same, you need to delete (forget) the network on the device then reestablish it. It is somewhat common. 
 

If no option for delete  network on the device, factory reset the device. 
 

The other issue may be the router wifi security settings are different (set higher than the older router) as some older devices do not support higher security. Also many iot devices need to be on the 2.4 GHz band.
