My house is a single-storey long rectangle - about 10m x 35m. At the eastern end is the main bedroom, at the western end is the garage and storeroom.

In my study/office (about 7m from the eastern end) is a Netgear R6400v2 which serves as my main router. It runs two wireless networks - 2.4gHz ("Wifi 1") and 5gHz ("Wifi 2") - and I use both for devices throughout the house. The fibre termination point is next to the R6400.

There is a Cat 5 cable running through the ceiling from the R6400 to a Netgear DGN2200 in the bar, which sits about 10m from the western end. The DGN2200 runs only a 2.4gHz frequency on its own network ("Wifi Bar"). It is configured to act purely as an additional network in case devices on the western end of the house can't see the signal from the R6400. However, devices on "Wifi Bar" get far slower throughput than those on "Wifi 1" and "Wifi 2". The signal strength on "Wifi Bar" has gradually become poorer, too.

In the lounge is my home entertainment setup. About six devices (TV, consoles, AVR, etc) all connecting to either "Wifi 1" or "Wifi 2" because the throughput on "Wifi Bar" is too slow.

I'm putting in an Wifi-enabled inverter (it does not have a hardwired capability) in the storeroom (about 25m from the R6400) but neither my phone nor my missus's phone can pick up "Wifi 1", "Wifi 2" or "Wifi Bar" in the storeroom. I don't have much hope for the inverter being able to pick up "Wifi Bar" despite the short-ish distance. Even then, the throughput won't be quick enough for me to effectively control the inverter.

I'm now thinking about putting in a true mesh network so that the inverter gets proper signal and speed and possibly a switch near the home entertainment centre in the lounge so I can hardwire most of the devices there. I would repurpose the Cat 5 cable in the ceiling to go to the switch.

Any suggestions about which mesh network to buy? Having had good experience with Netgear, I looked at Orbi. My eyes watered when I saw the $$$. I'm really not keen on the cheap Chinese backdoor-enabled shit; even TPLink raises my eyebrow.
 
Mikrotik :)

Could you upload a rough diagram of your place, incl where each netgear device is + where the inverter will go.

Cheapest solution will be a Mikrotik HAP AC2 setup as a wireless repeater, to sort out the storeroom wifi. Next step would be a full Mikrotik mesh setup.

"The signal strength on "Wifi Bar" has gradually become poorer, too."

Check the Wifi channels are set to auto, then turn off your router + other wifi points for 5min, then start them backup. This *should* let each device adjust it's Wifi channel to the least used channel, which translates to less interferance, better coverage and better throughput.

Those Netgear devices are old AFAIR, so please check that they are running the latest firmware.

with that kind of distances etc cat5e is still good enough, ive been pushing 2.5gb over my 10m cable for well over 1 yr now. Mesh is by far the best way to go, Cannot go wrong with Mikrotik as suggested above. Personally ive been using Ubiquiti for my APs though but they are expensive. At the moment im testing Reyee and have been pleasantly surprised by the Value but I understand its not everyones cup of tea. Good Luck!

You don’t want a mesh network.

They don’t work amazingly.

You need to optimise your current setup before you try anything else.

There’s probably something messing with the network or one of the APs isn’t in the right location.

TV inbetween you access point and the pc? That’ll drop your connection.

Same with a microwave or anything large and metal.

do a channel scan to see what WiFi channels are active in the area and make use of any channels available - eg use channel 6 if other wifi points use 1 or 11.

Here's a diagram:

Red dot on the left is the R6400 (and broadcaster of "Wifi 1" and "Wifi 2"). Red dot on the right is the DGN2200 (broadcaster of "Wifi Bar"). Blue dot is the inverter. The line between the right-hand red dot and the blue dot is a firewall (goes all the way up to the roof tiles). No devices receive signal from the DGN2200 in the room where the blue dot is.

I'll check the channels ASAP. Already noticed that the R6400 has a set channel instead of being set to auto. I'll check the DGN2200 shortly.

As far as I know, both routers' firmware versions are the latest.

Thanks - I've been looking at the Mikro Audience as a decent option. Deploying a second Audience or ordinary Mikrotik AP to create a mesh is one of my options.

Shot. I'll start with a channel scan and hard assignment but I recall that was one of the things I tried during my last attempt to optimise the setup.
 
AFAIR both of those routers are quite old, check their firmware and update it if your comfy doing that.

This might help a bit with overall Wi-Fi throughput / coverage asthey *may* optimise the Transmit/Receive voltage or allow you to manually tune it.

Off the top of my head the Rxxxx/R6xxx models are for SMB/enthusiast and the DGN2xxx was more home / soho. Taking that into account you can try the following:

Turn off DGN2xxx ; Plug R6xxx here. Check signal by the inverter with Wifiman. Put things back to normal. post screenshot here please. :)

You might be getting no signal after the building-firewall, because the DGN2xxx is "weaker" or both need to be tuned properly like @JollyJamma mentioned earlier. A quick switch should confirm this. If it still doesn't then some look at what can be tuned, you might have 10x neighbour Wi-Fi all on the same channel as Wifi1/2/bar.
 
You need to use proper wifi access points, not the entry level ones you currently own.

I’ll post a link to an AP that well known to work well.

Normal routers and stuff that you can buy at incredible deception are weak and poor value.

Put a couple of those up and you should get much better coverage.

Just saw the above.

I setup a Cudy mesh system for my mate and it was so simple and easy for full performance around the house now, not sure what jolly is on about but the Mesh worked with zero issues.

Only one ap had to be hardwired for an ethernet backhaul as it was going through 3 concrete walls to see the other one.

At home i have the Google Nest Wifi points that also were easy to use and perform well.
 
Maybe it can help a little bit, but i've deployed the following setup:
- unmanaged switch (maybe tp link or some cheap 8x1GE switch)
- Gateway (Opnsense VM)
- 3x RE605X wifi extenders (AP mode), these were on sale and cheap over here

On each RE605X i've disabled DHCP and the GE interface is connected to the switch, switch is connected to the mini server (running the VM as LAN gateway), uplink of server is connected to fibre ONT directly (could sniff the correct VLAN's to use here). Each RE605X uplink discovers a DHCP interface for management, all rest wifi users are independent DHCP clients registered on Opnsense FW.

On each RE605X I have configured SSID1 (2.4GHz, all same 2.4GHz password) and SSID2 (5GHz, all same 5GHz password). SSID1 on AP1 = channel6, AP2 = channel1, AP3 = channel11. SSID2 on AP1 = channel58, AP2 = channel106, AP3 = channel138. I think i set the power at medium for AP2 (middle of house), allowing the wifi terminals to easier switch between better wifi signal channels (of same SSID) as we move around the home.

Here is a brief snip of channels and overlap (use the DFS for 5GHz): https://d2cpnw0u24fjm4.cloudfront.n...nel-Allocations-5GHz-and-2.4GHz-WLAN-Pros.pdf

The above is working like a charm for us. Hope you can get something useful out of this that could help you without upgrading to complete mesh setup. Mesh setups are abit spicy here atm, so got away with the above as a cheap alternative.

"Smart roaming": like a cell network where it offloads you (all nodes aware of each other)?
 
The link that I provided appears to be marketing for a mesh system or what?
Answered my own question by scrolling down. I was referring to this one previously.

I read like my ass when I bought the ones I have now. They do not support mesh.

Ok cool. I’ve never really found mesh networking to work all that well.

I’m more of a fan of using better quality access points and tweaking the settings with one wifi username and password.

Access points are often dumb regardless of the tech - I’m hoping wifi 7 will make them less dumb.
