Asus AC87U firmware enigma.


I use my Router as VPN client for my Samsung Smart TV. The purpose is to be able to access region-restricted websites, such as Netflix.

The Asus AC87U worked very well for this purpose, but after updating to a new firmware videos are not loading anymore, if connected to VPN.


The same applies to YouTube. The main page loads fine but no video can be played. The message appears that a problem has occurred and I should try at a later moment.


The last firmware that works is Version 3.0.0.4.378.5134

The next release Version 3.0.0.4.378.9177 doesn't work.

The change log is:

Any suggestions on what causes this problem?
 
At least for Netflix, it's probably not the router but Netflix. Netflix has started blocking all access through VPNs to prevent what you are doing. If you do a google search you can find a lot of references.
 
Thanks for thinking with me! No, it is not the geo blocking of Netflix. The problem occurs only with firmware version 3.0.0.4.378.9177 and later. Via cable and Wi-Fi. Older versions work fine. Also the problem is related to the combination of the AC87U and my Samsung Smart TV. I can connect to the web site. See all the available videos with picture and text, but if I click them I first see "Loading" and after 20 seconds the message "Some problem occurred, try again later." Must be some feature in the Asus firmware that the Samsung doesn't like. I just have no idea what it could be.
 
Samsung Smart TVs are broken. They try to use "localhost" as their hostname which is not valid. Try configuring a static IP on your TV to work around the issue.
 
No, that doesn't help. The problem is not that I cannot connect to the TV or that the TV doesn't connect to youtube. Everything works fine, I see all thumb nails on the screen, but when I click them, the video doesn't load. With firmware 3.0.0.4.378.5134 no problem. Same with AsusWRT- Merlin. Version RT-AC87U_3.0.0.4_378.50_0 works fine, later don't work. Strange!
 
If you enabled any of the AiProtection security features, try disabling them. Something the TV does might be triggering it, blocking part of their functionality.
 
Thanks for thinking with me!

AiProtection is disabled, QoS disabled, everything disabled that can create problems. I have two other routers, an Asus DSL-N55U working in E-Wan mode and a LinkSys WRT-150N with DD-WRT and working with OpenVPN. Both don't have this problem! I just don't understand where the problem is.
 
Have flashed the router with Asuswrt-Merlin version: 380.59 Beta 2. Have configured OpenVPN to connect only the VPN to the Samsung. So far working great.
