Hi @Tee thanks for the additional info, can you check that DHCP is enabled on the router, it will be in network/Lan settings or similar, the Samsung looks like it's reporting it's not being assigned an IP address, also make sure in the Samsung's settings it's set to be assigned an ip address automatically.
Hi @Tee can you check which firmware version your Samsung TV is running by going to support in the menu, the latest version is 1152.8 if you're not on this version you should upgrade to it, as you can't connect to the internet with it you'll need to download the firmware file and extract it to a USB stick and select the upgrade via USB in the menu. Here's the download link https://www.samsung.com/au/support/model/UA55NU7100WXXY/#downloads
Connecting via your hotspot was my next suggestion but you’ve done that already! No need to USB update if it’s saying no update available, it would be interesting to see how an Ethernet connection will go but I’m guessing that’s not convenient to do?
Hi @Tee Yes if you can find an Ethernet cable for testing only it will help eliminate certain chipsets in the Samsung, the TV will have a WiFi module in it separate from the LAN chipset, what happens sometimes is that as new devices and hence new generation chipsets appear on the market, vendors need to update their hardware compatibility lists in their device firmware. There's a good chance either the Samsung is not on the Netcomm's list and vice versa.
I would be checking these things.
>Firmware is the latest version on the Netcomm router, you've already confirmed the Samsung is current.
>Confirm that the Netcomm is broadcasting in mixed mode 802.11 b/g/n. the F12 is a 2.4Ghz only model
>Check that the Samsung hasn't got a setting enabled that is only looking for a 5Ghz network.
>Temporarily disable encryption on the router by switching from WPA2 or WPA to NONE see if you can connect then.
>Try a factory reset on both the Samsung and the Netcomm but make sure you have your TPG login details available to enter into the Netcomm again.
Samsung support was incorrect saying it was a TPG issue, it's either a Samsung or Netcomm problem (or a combination of both) as the router runs Netcomm firmware not customised by the ISP
please report back how you go.
