The new configuration of the router had some quirks.
Thinking I had it all set up, it turned out that for some reason, IPTV didn’t pass: the set-up boxes had no connection to the Internet. Resetting them didn’t help – that’s what made this clear.
Where there is one VLAN for Internet access, this is routed to ports 1, 2 and 3; over LAN1 (connected to WAN1) or LAN2 (connected to WAN2 – the fast port). IPTV is bridged directly to it’s own LAN and port, and that seemed to go wrong. (VOIP works regardless the WAN port used – the lines are both registered at the provider).
This was in the very early hours of today, and there was no tie to figure it out. So I looked for a backup of the configuration, found a number of older ones, and restored the configuration from the latest of that set, reconnected WAN1 to the internet and set up Port WAN2 as backup. Some things still need to be done, but at the moment, everything is now in working order. So I created a backup of this installation.
And just then I found the pretty recent backup I was looking for…
Well, given the time I didn’t restore from that one. There is still some work to be done to swap the two lines. Unless the ISP has another idea to get the connection working at the intended speed of 100Mb – symmetrical.
I got an answer on my question to Draytek about this issue: Is it a router setting that causes this? The answer is: No, it’s ‘built-in’.
AS they put it (in Dutch)
De WAN 1 is een 10/100 Mb poort. Hiervan is WAN<>LAN doorvoersnelheid ongeveer 50~60 Mb/s. De WAN 2 is een 10/100/1000Mb poort en
hiervan is de doorvoersnelheid ongeveer 100~110 Mb/s. Onze advies om de WAN 2 te gebruiken.
Shrt translation : WAN1 is 10/100 Mb, WAN to LAN throughput is about 50-60 Mb/s. WAN2 is a 10/100/1000Mb port where throughput is about 100-110 Mb/s.
We recommend to use WAN2.
So in stead of 100 Mb, that WAN1 port is actually a 50Mb port – so 50%. WAN2 is even worse: the speed (given you can run full speed (1Gb/s)) your port is actually 1/10th!
So if I want to have full advantage, I’ll have to use WAN2. No problem, all is set up to work that way – just have to see if that works for television as well. And the max speed I got when testing it, was only(!) 70 Mb. Faster indeed though not the 90 I would expect, but it might be that router traffic interfered.
However, if I decide to go any faster (500Mb is possible) I’ll ned to replace the router – and heavily check te actual throughput.
