 Hi, thanks, 
  
 
My Internet Service Provider is Movistar Chile.
 
 
 - I have a 940 Mbps symmetrical fiber-optic plan.
  
 - The fiber-optic cable is connected to the Movistar WIFI 6 PLUS HGU RTF8225VW ASKEY AIROHA router (ASKEY COMPUTER CORP).
  
 - I have disabled the WIFI on the router to manage the wireless network through my Deco mesh system.
  
 
Connections to the Movistar router:
 
 
 - Deco Mesh (main unit): connected to one of the Ethernet ports on the router. 
  
 
   - It uses the Ethernet cable that came with the Deco Mesh X50 package.
  
  
   
 - Movistar IPTV: connected to another Ethernet port on the router. This service seems to use different ports or specific technology for IPTV.
  
 
Deco Mesh configuration:
 
 
 - The main Deco unit has two additional Ethernet ports in use: 
  
 
   - One connected to an Ethernet cable running to the first floor, where another Deco unit is located. 
    
 
     - This connection uses a Cat 5E Ethernet cable previously installed by Movistar when they set up a repeater included with the plan. However, the repeater was very poor, providing only ~200 Mbps (though symmetrical).
  
    
   
   - The other directly connected to my PS5.
  
  
   
 
 
 
I share a draw of my current network
 
 
 

 
 
 last test performed next to the main deco (with wifi macbook)
 
 
 
 
 
It seems that being closer improves the upload speed.
 
I should buy a better ethernet cable to connect the router to the main deco and not use the one that came in the package?
 
I also know that it is much better to have a router in bridge or "passthrough" mode (the Movistar router has a switch to activate it faster), but I think I would have problems with the IPTV connected by cable and the IPTV connected by wifi.
 
Or maybe I should have a better router? that is compatible with my Deco mesh x50?
