I'm having the same problem. Until yesterday it was working fine, but I had to take my tv down to adjust the wall mount and I forgot to put the Ethernet cable in.
Took it down and connected it back up and now it's saying there is no cable inserted , I thought maybe the cable was damaged, but when I changed it to one I've used many times before, nothing changed, still won't recognise it.
tried resetting the network. restarting router. changing chords (as mentioned)
nothings working. This is like the 4th weekend I've wasted trying to fix Samsung bugs, like the above user I had to return the Samsung q90r soundbar as the rear speakers wouldn't connect. I had the same problem once my son unplugged them yesterday and was told by Samsung workers on the live chat that I would need to return it again. And like the commenter above, I was staring to worry that the store I bought it from thought I was scamming them. Thankfully I fixed it on my own, after trying something none of the 8 Samsung workers told me and that was holding the id set button on the soundbar.
anyway I digress, but I just wanted to illustrate all the trouble Samsung has put me through and being an Apple user, I guess I'm just used to better quality products, products that akways work, ALL THE TIME and if they don't Apple will bend over backwards to accomodate. Whereas the Samsung workers don't even seem
to understand the products they're meant to be helping you with, one worker even told me to check that my speaker wire wasn't damaged.....uh the Samsung q90r is a wireless setup????? And there's plenty more I could add, but this is not the place.
ill probably get told by the Samsung workers to return this tv now, which btw is the same as the above person, the nu7100 65 inch. But I just don't understand why Samsung puts out such buggy products and why people swear by them, all the people I know that swear Samsung is better than apple, make me think they've just gotten used to products catching on fire in their pockets and constantly being bug ridden.
im willing to bet money, that Mt problem will not be resolved and I'll likely get told to visit my local registered provider.
well Samsung balls in your court, I hope you prove me wrong, I'm really tired of this substandard service and wasting all my free time adressimg stupid bugs that a 1st rate business would never release in the first place. In saying that though, the q90r has fantastic sound for a soundbar. So credit where it's due.
