The typical Morningside smart-home callout looks the same every time: the router is new, the broadband is fibre, the Wi-Fi analyser on the phone shows a strong signal in every room — and yet the video doorbell is offline, the thermostat says "connecting", the porch camera has stopped recording, and two of the four smart plugs need a re-pair before they'll come back. Nothing on the network looks broken. Everything on the network is broken.
This is one of the most common jobs we see in the older Morningside villas and tenements now, and it almost never gets diagnosed correctly by whoever fitted the router. The problem isn't signal strength. It's that modern Wi-Fi is now optimised for phones and laptops, and smart-home devices — the ones you actually want to be reliable — are the last thing on the router's mind.
What's Actually Happening on the Network
Wi-Fi runs on two main bands: 2.4 GHz (slower, longer range, better through walls) and 5 GHz (much faster, much shorter range, dies through brick). Almost every smart-home device made — doorbells, thermostats, most plugs and bulbs, older cameras, garden sensors — is a 2.4 GHz-only device. It has no 5 GHz radio at all. That's a deliberate design choice by the manufacturers: 2.4 GHz travels further through Victorian walls and uses less battery.
Modern routers, especially the ones ISPs ship as standard now, run both bands under a single Wi-Fi name and use a feature called band steering to shove clients onto whichever band the router thinks is best at that moment. It works fine for phones and laptops that have both radios. It's a disaster for a 2.4 GHz-only smart plug that can hear both bands during setup and gets nudged towards a 5 GHz signal it physically cannot use. The device pairs, works for a day or two, then quietly disconnects the moment the router decides to re-steer it.
Why Morningside Homes Make It Worse
The building stock here stacks the problem up. The Victorian and Edwardian villas along the Braid Road end and off Cluny Gardens have thick stone external walls, lath-and-plaster internal walls, and — this is the one that surprises people — steel lath under a lot of the older plasterwork in ceilings and hall dados. Steel lath is essentially a very effective 2.4 GHz shield: signal reaches your kitchen and dies in the hallway before it gets to the porch doorbell.
Tenements around Morningside Road, Comiston Road and Bruntsfield Place have the added issue of neighbours: every flat above, below and either side is broadcasting its own 2.4 GHz Wi-Fi on the same three usable channels, and by six in the evening the airtime is genuinely full. Larger detached properties towards the Hermitage of Braid have the opposite problem — the doorbell is thirty metres and one stone bay window away from the router in the study, and there's simply no signal at the front door at all.
A Bench Example: Six Devices, One Fix
A recent Morningside job on a bay-fronted villa: a Nest Hello doorbell that had stopped ringing indoors, two Ring outdoor cameras dropping every hour, four Hive smart plugs that would stay online for a day and then vanish, and a Hive thermostat that refused to reconnect after a router reboot. The homeowner had been through two ISP engineers and bought a mesh system. Nothing had worked.
The fix was on the router settings, not the hardware. The mesh had one merged Wi-Fi name for both bands and band steering was on by default. We split the 2.4 GHz radio off onto a separate Wi-Fi name — call it HomeName-IoT — turned band steering off, locked the 2.4 GHz radio to channel 1 (an audit with a Wi-Fi analyser showed channels 6 and 11 were saturated by the neighbours), and re-paired every smart device onto the new IoT name. All six devices came back and stayed back. Total on-site time was about ninety minutes, most of it spent walking round holding a phone next to smart plugs.
Fixes That Actually Work
Split the SSIDs. The single biggest fix on almost every callout. Give the 2.4 GHz radio its own Wi-Fi name, dedicated to smart-home devices, and leave the 5 GHz on the main name for phones and laptops. Every consumer router made in the last five years supports this in the admin panel; most just hide it behind an "advanced" tab.
Turn off band steering. Sometimes called "smart connect", "band select" or "seamless roaming". It exists to make phones happy and it makes smart devices miserable. Off is the right setting.
Pick a fixed 2.4 GHz channel. Auto-channel switches during the day and every switch drops smart devices for a few seconds. Set the 2.4 GHz radio manually to channel 1, 6 or 11 — whichever a quick Wi-Fi analyser scan shows is quietest in your part of the building.
Move the smart hub, not the router. If you have a Hive, Philips Hue or SmartThings hub, run it on Ethernet to the router and put the router itself somewhere central. Wi-Fi extenders for smart hubs cause more problems than they solve — they double the number of hops each smart command has to make.
Re-pair after any router change. Smart devices bake the router's MAC address and Wi-Fi settings into their config at pairing time. Change the router, the Wi-Fi name, the password or the security type, and half your devices will need a factory reset before they'll rejoin. There's no way around it — this is a device-firmware limitation, not a Wi-Fi one. Related reading: how to diagnose Wi-Fi dead spots at home.
Fixes That Don't Work
Buying a faster router. Wi-Fi 6 and Wi-Fi 7 gear is genuinely faster for phones and laptops, and makes zero difference to a 2.4 GHz thermostat. If the current router isn't older than about 2019, upgrading is rarely the fix.
Wi-Fi extenders as smart-hub bridges. Extenders halve throughput and double latency, and most re-broadcast on a different channel that smart devices then have to roam between. A cable from the smart hub to the router beats any extender you can buy. On the same principle, our powerline vs mesh comparison is worth reading before adding more wireless kit.
Turning WPA3 on. Many smart devices — particularly anything two or three years old — can't authenticate to WPA3. Keep the 2.4 GHz IoT network on WPA2 (or the WPA2/WPA3 mixed mode if you must) and only enable pure WPA3 on the 5 GHz main network.
When to Call for Help
If you've split the SSIDs, turned band steering off, picked a fixed channel and the devices still drop, the problem is either environmental (a steel-lath wall between the router and the porch doorbell) or a bad hub. A signal survey with a proper Wi-Fi analyser will show which — it's the same first step we run on any Wi-Fi callout, and it takes about twenty minutes to walk a typical Morningside villa. From there it's usually one of three fixes: a wired access point at the front of the house, a dedicated Ethernet run to the smart hub, or a device-firmware update that the app hasn't offered yet. For homes where the smart kit is part of a hybrid-working setup, our home and office callouts can cover the whole network in one visit; when it's the smart app itself that's misbehaving, software troubleshooting often sorts it remotely.
Neighbourhood Notes
The pattern here — 2.4 GHz smart devices vs modern band-steering routers — is the same in Bruntsfield, Marchmont and Newington as it is in Morningside; the older stone-and-lath building stock just makes it more visible in this part of the city. If the same devices dropped in your last flat in Leith or Stockbridge, it's almost certainly the same underlying config issue rather than anything about the individual property. Livingston new-builds and Corstorphine bungalows tend to have less signal-blocking material in the walls, so the same devices often muddle along there — right up until the router is replaced.
The Short Version
If your smart doorbell, thermostat, cameras or plugs keep dropping off Wi-Fi in a Morningside home, don't buy a new router and don't buy new devices. Log into the router, split the 2.4 GHz radio onto its own dedicated Wi-Fi name for smart devices, turn band steering off, and pick a fixed low-traffic channel. Re-pair the devices onto the new IoT network. Nine times out of ten that fixes every one of them at once.
