ASUS RT-BE88U

With our house from the sixties, a wired backbone is not an option. That is why I opted for a strong router in the middle of the house. With Wi-Fi 7 I can use the latest technology. Most routers with 6GHz are not as strong as this one on 5GHz. Because it will take a while before 6GHz is the standard, I opted for a lot of speed on the 5GHz band and to leave out 6GHz. This is not only fast, but also has 8 LAN ports. The software is very extensive, but still simple. All in all a great product.

Gets my full 4 GB/sec via PPPoE, something I had not encountered before except with the standard box. I think it wants to be even faster, 1 specific speed site owned by the well-known red streaming service does not seem to be really pinched and sometimes gets 6-8 gbit.
With 10 gbit you actually want to use fiber optic where possible, just because of the power consumption of 10 GbE.
The XGS-PON ONT is connected to the WAN port and the switch is connected to the router via a glass module. Seems quite efficient compared to what I had (mini PC as router).
Both the WAN port and the SFP+ port can therefore be used simultaneously.

Furthermore, you have to set the following at the large green provider of, among other things, fiber optic internet: at 802.1Q VLAN ID 6 and then IPv6 on Native and Interface PPP, Stateless and everything else there on Enable.
For TV, you have a button IPTV with an ISP Profile at LAN. There is a message here "Due to hardware limitation, IGMP proxy cannot co-exist with IPTV function." I don't watch TV.
