You mentioned that you're having the same issue even if it's connected hardwired.
Yes, mate. Ethernet light is still on. TV says it can't find the modem. I don't understand it all, but I've looked into 5Ghz vs 2.4 etc etc. It just seems as though the TV can't recognise the modem without some sort of manual intervention each time it's turned on.
To be clear, I am very grateful for replies here as I totally get it's not a TPG issue. TPG have been great and our connection uptime and speeds are good, but I'm just trying to rule out the modem as being the cause!
Thanks for the ongoing assistance here.
Hi @Tee It's disappointing that you're still experiencing this issue, I've just checked the Samsung support site and can now see a later version of firmware for your NU7100 since last it was suggested on page 1 of this thread, it's the next logical step, here's the link to Ver 1202.3 https://www.samsung.com/au/support/model/UA55NU7100WXXY/#downloads
We can only provide a basic troubleshooting with a limited information about Smart TV, If the issue on your Smart TV is still persist, we recommend to contact the manufacturer to provide a proper troubleshooting.
Hi just an update.
As per my original post my mystery problem still persists with no found solution yet. Samsung still says it’s an internet providers issue and vice versa. I’ve tried troubleshooting all that’s been suggested (including changing to a high end router, installing power line Ethernet adapters) except I haven’t tried changing internet provider or getting Samsung to change the tv’s wifi module. - @Tee
@Tee You say that you've tried a high end router and could still not solve your connection issue to your Samsung TV, this also shows that it's not a TPG issue as Samsung suggests, you really need to try the newer firmware update.
Common sense shows that it's either a router manufacturer and/or TV manufacturer issue, 2 different model routers with the same symptoms then points the likely offender to be the common denominator, the Samsung TV.
