Thanks for the article link. However my Tablo is hardwire to my main AT&T router so the Tablo quad is not on Wifi.
To be more specific, I can access Tablo via my AT&T wifi on any of the devices using the Tablo app. I can not get any video to play on any device connected to my network extender either 2Ghz or 5Ghz signal. I get a playback error message when trying Live TV or a recording.
As stated in my first post all other streaming services both video and audio works with my current network extender.
My first suspicion is that the devices connected to your extender are receiving IP addresses in a different subnet than those connected directly to your AT&T wifi.
The fact that all your devices can reach streaming services is not a good indicator of whats going on - it is expected that all subnets can reach the internet, but what’s needed is that one subnet can reach the other subnet.
Make sure you are using the extender mode, not the access point mode. If access point mode it could be creating a new network? Tablo won’t work if it is connecting to a different network, like a guest network. I have a Dlink extender and Tablo is working fine on it.
that is strange. the next step i’d propose is to take a packet capture from a device connected on the extender network to grab what’s happening specifically on the network and see what the problem is. Install Wireshark, select the wifi interface, start the capture, attempt a connection to your tablo, let it fail, stop and save the capture and then we can look at it.
If you are willing to spend the money, upgrade your entire network to a mesh system. Eliminates all those problems and inconsistencies.
Personally, I have a 3 device Google Wi-fi system covering the house, a large shed and almost acres (I’m in the country, so no real obstacles but my own walls). No Tablo or any other problems anywhere. And you get the seamless handoff between access points, unlike some extenders.
