Since some devices use Auto-MDX a crossover cable could indeed work on some things but not a TV.
But let's say your network is fine. It's clearly a warranty issue so you take it back for another or get it fixed.
Got a blu ray c6500 player and I have constant network issues
I've got it connected via a wired (Ethernet) cable and it won't connect to the network!
Error comes up with: ip auto setting failed
It has a MAC address, IP address and subnet
No gateway or dns
What's strange is the subnet is set to 255.255.0.0 - it should be 255.255.255.0
Also the IP address is 169.254.116.45 - my network is on 192.168.0.xx
Dhcp is enabled on my router
I've tried the cable in my ps3 and Xbox and they both work fine! So this is not a network or router issue
I have the latest firmware from dec 2012 too
I tried a wireless connection and that does seem to work however it's slow and drops off all the time! So I want to use my wired network
I've also reset the box twice - no luck
I've gone over the setup again - no luck
Why doesn't the wired network work? This is basic stuff Samsung!!
