Please help optimise my network. Cables everywhere but the WiFi is now excellent.
Hi all.
I've recently upgraded my network and could do with a hand in further optimising it please.
Here's the current set up:
The house is a mid terrace (attached pysically to a another house on the left and right in my diagram). It's alsl over two floors, with 3 bedrooms (or 2 beds and an office in my case). Size wise, it's around 1000 square feet, built in the late 60s of cavity walls (outer brick, inner breeze block, with an insulated gap between them). The windows are double glazed with "energy glass", which blocks WiFi (i lose around 20dB of signal through the glass alone). Internal walls are concrete breeze blocks and these cause the signal to be almost non existent without having all these APs in such a small space..
3x Deco BE65, each one has 4x 2.5 Gb LAN/WAN ports. They are Wi-Fi 7, tri band. Each one is hard wired directly to the main one in the livingroom using solid copper outdoor rated cat 6 cable.. They do not support PoE so are powered off the electrical sockets..
A Deco BE25, outdoor unit. Currently powered from an outdoor electrical socket temporarily. This can take PoE and is dual band WiFi 7.
The layout: Please see diagram for current cable runs.
1. Livingroom Deco BE65, which has the following:
- LAN 1: This acts as WAN from the ONT. No internet supplied routers so no NAT issues.
- LAN 2: Gigabit switch which links to the TV, games console, and a Tapo hub.
- LAN 3: Cable to the Kitchen Deco.
- LAN 4: Cable to the Office Deco.
2. Kitchen Deco BE65.
- LAN 1: Hard wired directly from the livingroom Deco on its own cable.
- LAN 2: Has a cable going to one camera out of the front of the house (bottom of the picture). This is currently powered by a mains electrical socket but ideally I want to free up that socket.
- LAN 3: Another cable goes to a camera about 25 metres away, off the top of the picture, which is currently powered by a PoE injector on top of one of the kitchen units.
- LAN 4: Spare.
3. Office Deco BE65.
- LAN 1: Hard wired directly to the livingroom Deco on its own cable.
- LAN 2: Cable to a streaming box on the TV.
- LAN 3: Cable to the docking station for my work laptop.
- LAN 4: Cable temporarily routed through a cracked window (on vent) to the outdoor BE25.
No Spare LAN port but I do have a spare gigabit switch I could move the TV and work laptop to if needed (they only have gigabit LAN so no big deal).
4. Outdoor Deco BE25 which is attached to the outside wall in my back yard.
- LAN 1: Cable from the office Deco.
- LAN 2: Spare. No other LAN ports.
WiFi:
I have zero concerns about with this setup as internally, a get an almost full signal in every room. I have a few smart plugs and smart speakers around the house and apart from that, I use my mobile and sometimes my work or personal laptop on Wi-Fi.
Externally, the BE25 is enough for me to get signal when sat in my car which is about 12 metres away and behind a tall wooden gate. The BE25 is currently about 8 feet up a wall but I could move this higher if it may help.
What do we think is the best way of simplifying this lot?
Ideally I want the two outdoor cameras to be powered by PoE to avoid running power cables and also avoid taking up valuable electrical sockets in my kitchen. I was thinking of using a LAN port on the kitchen Deco to feed into a gigabit PoE switch and having both cameras running off that, as it would give me room to expand the number of cameras in future.
I want the outdoor BE25 to be powered by PoE so I was thinking of just taking the 2.5 Gb PoE injector upstairs and using that between the office BE65 and the outdoor BE25.
I think some say it would be better to add a switch between the 4 Deco units but my main concern is the indoor units. The outdoor BE25 while used a lot, isn't something I would worry ahout being connected to the office Deco BE65 as they all support and can automatically switch to wireless backhaul if one of them was to go down.
I'd love your input.
Thanks!
