Our TV (UE40J6300) has lost it's wireless connection to our home network. When trying to reconnect it I'm getting the following message:
"Invalid MAC Address, call Samsung support"
Have tried the TV reset function but no luck. All our other devices, phones, laptops etc connect without a problem.
Our TV is only just over a year old. I have seen posts on other forums about this problem with Samsung TV's.
Any help / suggestions on how this can be fixed without the need for calling out an engineer would be appreciated.
Solved! Go to Solution.

Hi @abdure99 ,
What's the model code and full software version of your TV? (Menu / Settings > Support > Contact Samsung / About This TV.)
What troubleshooting have you tried? Anything advised in this thread, for example? And do you have any other devices on the same Wi-Fi network?

After months of it not doing it (because i leave it on sleep mode indefinitely and cannot shut the TV else it loses connection) it loses connection again. Been screwing around with it for a long time. This stupid TV is a constant battle and i will never ever buy a Samsung product again.

Solution which has worked for some:
Firstly ensure you have latest firmware, if still issues
Power off (plug out from the outlet ) the TV for 30 seconds and plug back in in
Go to Menu->Support ->Self Diagnosis ->Reset
This will reset TV settings and will need to power on TV at this point
This is new settings and you need to go through setting your language etc.
This will try to reconnect , though possibly may connect to modem but not Internet
If still an issue, reset DNS Network -> status -> IP settings and set DNS to or 220.127.116.11 or 18.104.22.168 or 22.214.171.124
Now hopefully you will be able to connect to Internet
your apps would have been lost though and so need to go to Apps and download favourite ones again.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.

Thought I'd chip in as I've had the same problem on and off for a while. Invalid Mac address and unable to pick up wireless connection. Having read through a few threads I decided to take the back off the TV and get the model number for the WiFi module to replace it. Quite a lot of dust had accumulated so blew as much off as I could, once I'd put the back of the TV on and set it up again it connected straight away and has been fine since . Possibly dust build up around the module is affecting connection? Anyway I've ordered another module online for less than £10 in case it goes again.

I’ve had same issues - MAC, IP settings, DNS settings all come back as 00.00 for everything. Around same time Smart remote stopped working for all functions except on/off and volume. Unable to attach to LAN Wired network or wireless or hotspot iPhone. Factory reset worked for TV then stopped working. Been through process several times. Sometimes doesn’t let me manually input settings. Just won’t let me select that tab. Smart remote never started working properly again. TV nearly 3 years old. For £1.2 K I expected more from Samsung. Customer services pleasant but unhelpful. Said I’d been through all steps he could suggest. I have to arrange repair.
I will keep messing about with. Have reset router etc. When working again in between was perfect except smart remote. I have Eero Mesh network/ Virgin Media Fibre broadband. No issues other devices.
