Hello @JIMAS,

thanks for your time to help me on this.

Yes, in a way you are right, a "simple" internet connection suffices to receive Netflix. That is what I have now, and I can play the movies/videos from Netflix and Amazon.

But I do not get the videos/films played in surround sound, (5.1). The previous router that I had before this, also had 4 LAN ports, but one of them was hard-wired as IPTV, the others were Internet ports. So, no fiddling with settings at all. That  router about 3 months ago was killed by a lightning strike that hit my house. By then, I had a good surround sound effects, obviously when playing videos/films encoded in 5.1 sound. Ever since I installed this TP-Link router I no longer have surround sound. Then I noticed that the LAN ports on this new router are "soft ports" i.e. you can configure anyone or all of them as INTERNET or IPTV ports. Hence, my belief that the lack of surround sound now is due to the fact that the signal is output by the router as an Internet/data signal, without the surround sound facility. This in a way contradicts your comment  Netflix and Amazon TV don't need any ports. If that was the case, TP-Link wouldn't create the facility to set the LAN ports either Internet or IPTV.

Any comments by you or anyone will be greatly appreciated.

Yes, I know about that set up. And those parameters are what I am after

I need to know if IGMP VERSION is 2 or 3.

Then in MODE what do I select:

Is it BRIDGE,

or SINGAPORE,

or MALASIA-UNIFI or MAXIS 1 or MAXIS 2,

or VIETNAM,

or PORTUGAL-MEO, or PORTUGAL-VODAFONE

or AUSTRALIA

or NEW ZEALAND

or RUSSIA.

After all those option you still have another one "CUSTOM" which on itself it has 8 sub-options to select, each option with multiple choices; this option alone is a nightmare if you want to try your luck and select one by one.

Those parameters are for sure to be supplied by my ISP (Home-Connect in Johannesburg), but they are such a bunch of uninformed and lazy bunch. They just told me to request that data from TP-Link. In a way if TP-Link were a bit more professionals here, they would interfere, contact the ISP and give me some help. But it looks to me that they are as bad as my ISP; TP-Link told me to search this forum for help. Can you believe how unprofessional they are? They just sold the router and tough luck if it doesn't work. This teaches me a lesson: NEVER BUY AGAIN OR RECOMMEND TP-LINK.

Any ideas?
