Toshiba TV connectivity

grahamhughes · Jul 19, 2014

I have a Toshiba 32W4333 TV. Connected to my old Orange Livebox router, the online services worked fine. However, I now have a netgear MBR1310 router using 3UK for internet connection. TV is connected by wire (as it was before). The router reports it is connected to the TV, and the TV's browser is able to access websites. Other devices connected to the router seem fine (web, email, etc.). However, the other online services on the TV report that they "require a valid internet connection", and none of the apps (like youtube) will launch. I have tried disabling security features in the router, but nothing seems to make any difference.

I'm limited in terms of what I can see the TV doing, but it appears from what the router tells me to be making connections on port 443, to digital.dl.toshiba.com (which appears to relate to firmware updates) , static.admediate.accedo.tv, chart.apis.google.com, app.arqiva.tv and data.arqiva.tv. There does not seem to be any problem connecting to these, other than that some at least seem to have invalid certificates (they seem to be hosted on AWS, and have Amazon's CloudFront certificate). I can't see how this would have been different when connecting by a different route, and presumably Toshiba TVs did not all stop working coincidentally when I changed network provider.

Toshiba don't seem to have much by way of support, and I'm running out of means by which I can diagnose the issue.

Any ideas?

Cheers,
Graham.

Hmm... Have you changed internet providers since than? You could always try port forwarding the TCP port 443 just to ensure that the connections go through smoothly.

Yes, changed from Orange (via BT landline) to Three (via 3G cellular). The connection to 443 is outbound, and nothing is configured in the router to block outbound connections. Other devices can connect to this port just fine. The only port-forwarding options are for in-bound connections, and none were set up on the previous router either (both were set to block all in-bound connections, with UPnP disabled on both).

I have just tried connected my new router to my old router, so I can use the old internet connection (I still have access to both) with the new router between the TV and the internet. It then connects fine, which I think exonerates the router and places the blame with Three. I can now see the TV connected to some additional sites, one of which does not have a working DNS entry in Three's service. I'm not convinced this is the only problem, but I am convinced that the problem lies with Three.
