Introduction: Fix Bad Mac Address on ROKU TV

I bout a ROKU TV and about 6 months into it I could no longer connect to the INTERNET with it. Showed a Mac address of All ZEROS. frustrating as it is the fix is pretty simple. After doing some research I found out that all ROKU TV's had something in common all of them have the same WI-FI card made at ROKU. I decided to dig deeper looking at the chip itself and discovered a lack of or not good enough grounding so I decided to try this .....

Step 1: Unscrewing the Back

very strait forward 1st unscrew the area where you put your connections in then undo the screws were the speakers are located. This is where the card is located

Step 2: Identify the Chip

The chips look the same throughout the different devices.
on it will identify ROKU and a Mac address and you should see an antenna

Step 3: Solder a Ground to the Chip Housing

Yes you read correctly. Get a piece of braided wire (make sure you tin the end before soldering to housing). lightly sand the metal to scuff up the chip housing for better connection. then do a quick solder connecting wire and housing being carful not to over heat the chip. (if you damage you can get a new one online @ e-bay for about $10) I also coted connection with a few licks of Fingernail polish to prevent oxidization in the future.
Then on the other end of ground I created a loop and tinned it to create a hole the screw can go through.

Step 4: Put It All Back Together

I put the screw back into the plastic housing and threaded the wire on to the screw.

Then I reattached everything

Step 5: Your Set to Go

you will now be able to find wi-fi connection and be able to log into your account again. YAY

Thank you for looking at my very first instructable hope I can get better and share more with you in the future.

    Soooo I was having this issue with my Insignia Roku TV and saw this posting, so I opened up the TV, and lo and behold, there was already a factory installed grounding wire running from the Roku chip housing to the frame (as if the company had found out this was an issue and did a quick and dirty fix). At that point, I went ahead and installed my own grounding wire, not expecting it to be of any benefit, but whatever....I already had the TV opened up so I gave it a shot....and the thing now works! Of course now I'm kicking myself that I didn't check the original grounding wire to see if it was still grounding the housing or not, before I began my work. I'm wondering whether perhaps applying the soldering iron to the housing helped reflow some bad solder joints of the chips beneath, and that perhaps was my actual problem.
    Regardless, thanks so much for posting this!

    I may have to look into this myself, my Insignia Roku TV has had intermittent connection issues for a long time now and tonight I finally noticed the MAC address went to ea:ea:ea:00:00:00 which I knew was weird. Power off restart fixed it for now but we'll see.

    I do suggest for those inexperienced with soldering electronics look up Electrically Conductive Adhesive as an alternative to soldering as you only need a conductive connection for ground to work. Putting the other end of wire to anything that attaches to metal frame should do the trick, I presume the screw OP chose will do such.

    I have the same problem with my 55p715 TV. But I've noticed an error at source.
    The wifi antenna is soldered to a steel plate that pretends to be an antenna. The problem is that both the mesh and the signal cable are welded to the same plate, causing a short circuit in the coaxial.

    Can anyone confirm that this fix *stays* fixed? My Roku TV with this problem will occasionally go back to normal for a while but the problem always comes back.
    Thanks!

    Thanks for the Instructable AND the follow up. I ended up running a cable through the attic, but may try this anyway. Thanks again!

    Question 1 year ago

    My Insignia Roku TV disconnects from the wifi some time after I turn it off. I lost the Roku remote so now I have to use the Roku remote app. Problem is, I have to disconnect and reconnect the TV in order to have it connect to the wifi again. Otherwise I won't be able to connect with the Roku app and turn it on.

    Would the wifi card grounding trick fix my issue? Just want to make sure before I perform surgery on my TV.

    This should work, sounds like how mine was acting before it went out.

    It could because that sounds like what mine was starting to do before it fully went out. Hope it works for you too

    This worked on a TCL 6 series. One day couldn't find wifi and Mac address was all zeroes Used soldering iron to scrape off some of wifi chip label to expose metal. Grounded with one of the screws that hold the TV mounting brackets.
