New Telus modem/router and wifi killed Smart TV

[TMVYLW]

We recently had Telus upgrade our equipment. We now have an NH20A modem and two B20A WiFi routers. 

Since having the upgrade, our Smart TV (Sony Bravia A80K) has no internet access, despite being connected to our Telus WiFi network with excellent signal strength. All our other devices (PCs, Xbox, iPhones) have Internet, and the Telus Optik TV works fine (we can stream Netflix via Optik TV). 

I have searched and tried different suggested solutions without success. Power-cycling everything. Disabling the 5GHz WiFi bands. Making sure the TV is on automatic time settings (there no option to choose between broadcast and network time).

I am now on the cusp of having Telus send a tech out to help. Are there any other potential solutions I should try?

I'd start with tech support for Sony. If everything else is working, Telus will charge if the issue is not with their equipment / line and they come to your residence.

Call for tech support over the phone. But I caution you to expect various levels of competence. My last call for support was a disaster and lead to a real Telus employee technician at no cost.

Telus tech support won't provide support for non Telus equipment like TVs. Since all the other services are working fine and it's just the one device having issues, in the highly unlikely event that a tech was sent out, they would definitely be charging for the visit.

Thanks for your reply. I really do not think this is a Sony problem. The Telus equipment we had previously worked just fine with the TV. It is the new Telus equipment that has changed things. The Sony TV just happens to be the symptom of whatever problem has been introduced by the new Telus equipment.

It'll be a Sony problem if it's the only device not connecting. Since the techs don't troubleshoot unsupported hardware, they will charge you if they come out and find the connection itself to be in working order and just the one device affected.

You never did say what your old hardware was. Your new hardware has the NH20A router (not modem) and a pair of B20A wireless access points (not routers). They use the same networking standards as the old Telus hardware. Does the Sony have a valid IP address that matches what the NH20A assigned to it? Do you have any custom network settings on the Sony like a static IP? Does it show an error? When you run the onboard diagnostics what does it say?

Have you tried removing the network connection settings on the TV and then reconfiguring them?

@TMVYLW 

Can you put a hardwire an Internet connection over ethernet or coax connection to direct your TV? 

Can you temporarily move your TV to a hardwire connection?

Or as suggested contact Sony. 

I had a similar issue when we had the "correct" routers supplied and my doorbell camera stopped working and would not login to wifi. Contacted the company, changed a bunch of configurations...and no work...even reset it to out of box condition and tried to connect to no avail.  Sent it back and bought a different brand and it all worked.

How did the smart TV get internet before? WIFI or Lan

Lan should connect with an auto IP address but WIFI  will need to be manually set with the user and password. (I may be wrong, it has been a while since original setup)
