SEC_LinkShare SSID is from your Samsung TV: SWL (Samsung Wireless Link)

Posted by Jeroen Pluimers on 2011/07/04

While playing around to improve the WiFi network reception of my Samsung LED TV, I enabled SWL.

It didn’t do much on the WiFi reception, but I found out that after enabling SWL, other devices could hardly find my regular access point any more.

Somehow, a very strong access point appeared pushing away all access points. The new access point had an SSID like SEC_LinkShare_######.

Though this wasn’t mentioned in the PDF  manual of my TV, a quick search on SEC_LinkShare+SSID indicated in the direction of Samsung devices.

So, when you enable SWL on your TV:

  1. your TV will become a local secured access point
  2. the SWL access point will be called SEC_LinkShare_###### (with 6 digits at the end)
  3. you cannot influence the WiFi channel used by the SWL access point
  4. there is no information on the password to connect to the SWL access point
  5. the SWL access point will potentially have a higher signal than access points further away (effectively blocking them)
Conclusion: Unless you have other Samsung devices that need the SWL, don’t activate it on your TV.

    Thanks. Very helpful advise.
    Did you find out where the password can be located to access the SWL?
    I am having problems linking my Samsung D8000 to the router. It simply cannot detect the router. Any tips on how to make it work are very welcome.

    Thanks, very helpful! Another problem is that the SEC_LinkShare-WLAN that is created by the TV always broadcasts on the same wireless channel than your router. If you change your router WLAN channel to 5 -> The SEC_Linkshare-WLAN will also change to 5. It always overlays your primary wireless internet connection and causes a channel conflict partially affecting stability and performance.

    Aftre switching off SWL (thanks to this thread) I could slightly improve my wireless connection to the TV.
    Tested on Samsung UE60D8090 connected via wireless, Belkin PlayMax router connected via 32MBIT cable model connection.

    Regards, Sebastian

    Excellent post. Was very puzzled by this LinkShare entry.

    Dead right about it selecting the same WiFi channel as the router. I also tried changing the router channel and the TV followed it!

    After contacting Samsung, I have been advised that this SEC ShareLink is to connect other Samsung devices (DVD, Blu Ray, Hi Fi.. etc…) wirelessly, to your Samsung TV, would have the passcode embedded in the device.
    Best thing to do is to turn the SWL off.

    I was able to break it and get the wpa2 key.. Now i am able to connect devices to my tv…. it took 10 secs for me.. A little bit of hacking but it easy..

      What did you use to get the WPA2 key? I’m anxious, as my TV is now wired and I want to use it as a wireless access point.
