iiiiii'm back. So some updates.
I ended up grabbing:
1. 2x NWA210AX's
https://www.amazon.de/dp/B08GY1WQ9M/
2. 1x NICGIGA 8 2.5Gb switch (with a 10Gb SFP+)
https://www.amazon.de/dp/B0BXSDS32C/ for connecting the various rooms to each other/the router
3. 1x VIMIN 6-Port 2.5G PoE Switch - Has 4x 2.5Gb POE+ ports and 2x 10Gb SFP+ ports
https://www.amazon.de/dp/B0C5D5PSS7/ for the APs
4. other assorted things (patch panel, keystones, RJ45 jacks for the AP's etc)
Currently I have my 1Gb DOCSIS connection (moved in btw). Have not bothered changing the router. I plan to probably add my ASUS router back into the mix next week (i'm really missing diversion) at least until the 2Gb FTTP is available.
At that point I will probably grab something like the normal version of this that has 2x 10Gb SFP ports instead of 2x25Gb SFP ports
( I don't need 25Gb, also I have no clue whether the SFP ports on my switches will play nicely with 25Gb because i read something about auto negotiation issues). Or one of the low power fanless ones that STH has reviewed.
I've not decided yet whether I will use both connections or condemn the 1Gb one (but i'm leaning towards condemning the slower one just because it's simpler)
For now the layout is: router - Ethernet - NICGIGA, connected to rooms currently being used - SFP - VIMIN connected to 2x APs.
Currently have 1AP on floor 2, 1AP on floor 1. And everything else is on the ground floor.
WiFi on the ground floor in the man cave is not great at all ( 50Mb compared to 700 -1000 on other floors) unless I connect directly to the router. But I suppose this is expected because of the concrete between floors. I’m not sure whether it’s worth getting another Zyxel AP to cover this floor, feels a bit overkill but in the end I will end up with a wired router so I have to plan for this. Is there another similar zyxel AP to the NWA210AX but just for smaller spaces? And probably wall mounted because I didn’t ask for a wire in the ceiling on the ground floor, though I suppose I could just run one directly from the router or one of the switches in the garage.
On the topic of wifi, is advice like the first reply here
https://community.zyxel.com/en/discussion/12829/nwa210ax-slow-performance the best advice to get a good connection and encourage devices to switch to the access point with the strongest connection to them? My phone does this but my oven for example is still connected to the 2nd floor AP for some reason (likely because that’s the one it was originally connected to).
Summary of the current plan is that as time goes on:
1. “Upgrade” router to an x86 box (isp router in bridge mode). Current plan is to pick something that makes sense that’s probably been reviewed / recommended by STH ( mainly looking for some 2.5Gb Ethernet ports and at least 2 SFP+ 10 Gb ports)
2. Find an appropriate AP solution for the ground floor man cave, realistically this and the garage are the only rooms that needs a strong connection on this floor, and they are next to each other. Would prefer to get something smaller than another NWA210AX but in the name of compatibility/uniformity I am willing to get another one.
3. Will add another NICGIGA switch as needed. Though realistically even though there are 14 or so ports through the house, I only really foresee 1-4 being in use simultaneously outside of the APs which have their own switch anyway.
Does this all sound reasonable? Is there some obvious thing i'm missing? Also……erm…..sorry for the wall of text lol.
