THE PORCH LIGHT
Hi there!
Anyone else spent a weekend trying to get a R300 plug to talk to a R3,000 router? You are not alone, and you are not bad at this. The plug is fine, and so is the router; it is one setting between them. So this week we’re looking at why smart devices keep falling off your Wi-Fi.
But first, a quick PSA to our home tech business owners and operators: Millennials and Gen Z now dominate most buying, and did you know that they want to clearly see your pricing on your website?
It’s true: if your pricing and packages are not clearly visible and accessible, they might even leave your site (without ever telling you why) and go to a competitor with clear prices instead. The lesson: Even if you have variable and quote-dependent pricing, create general package sets or ballpark “from” prices so you don’t scare customers away.
This week, we also look at:
The fastest uncapped internet if fibre has not reached you
A R264 box that keeps your router alive through an outage
Why your speed test looks great and Netflix still stutters
Four proper deals, including a flagship JBL at half price
And way, way more…
Hit reply and tell us what in your house refuses to stay connected. We are collecting the worst offenders.

Why your smart devices keep falling off your Wi-Fi
Ever bought a smart plug, opened the app, and watched it spin until it gave up? You didn't get a faulty one — your router did that.
Almost every smart plug, bulb, sensor and cheap camera on sale in SA only speaks 2.4GHz. That's deliberate: it reaches further, goes through walls better, and uses cheaper chips. Your phone, meanwhile, is almost certainly sitting on 5GHz.
When you set up a new smart device, the app hands it whatever network your phone is currently on. So oftentimes it gets 5GHz credentials that it physically cannot use, and the setup hangs.
The thing making that decision is band steering, sold to you as "Smart Connect" or "One SSID". One network name, and the router decides who goes where. Often a disaster, because IoT devices cling to whatever band they joined first and then get shoved to one they can't reach.
Three fixes, all free
1. Pair on the right band (free)
Before you set up anything new, get your phone onto the 2.4GHz network. If your router shows one name only, switch Smart Connect off temporarily, note the 2.4GHz name, join it, pair the device, then switch back.
2. Split your bands, but only on Wi-Fi 5 or 6 (free)
Give 2.4GHz and 5GHz separate names and put all your smart gear on 2.4GHz. On Wi-Fi 5 and Wi-Fi 6 routers, this is the most effective fix for chronic drops.
On a Wi-Fi 7 router, do the opposite. Keep the bands merged, because Multi-Link Operation needs them together to ride out interference. Splitting a Wi-Fi 7 network makes things worse.
While you're in there, lock 2.4GHz to channel 1, 6 or 11, and prefer 80MHz over 160MHz on 5GHz.
3. Fix the security setting nobody checks (free)
If your router is on WPA2/WPA3 mixed mode, that's a hidden cause of devices dropping days after they connected fine. The extra WPA3 broadcasting overwhelms older devices, so they reject the connection or quietly fall off later. Set 2.4GHz to WPA2 only and leave WPA3 on the 5GHz side.
One caveat on Eero and Google Nest: neither exposes band control. Your only lever is the guest network, which on many systems defaults to 2.4GHz.
The signal
None of this costs a cent. Get your phone on 2.4GHz before you pair anything, split your bands on Wi-Fi 5 or 6 and merge them on Wi-Fi 7, then drop that 2.4GHz network to WPA2 only. Do those three and most of the dropping stops.
FIVE SIGNALS
Smart insights, short and sweet
COMFORT iRobot wants to send a second robot out with the first one. The Roomba Duo pairs a main vacuum with a smaller unit for the tight spots. It’s still a concept, not a product, for now. Signal: If you're shopping this year, buy on the dock, not the gimmick.
CONNECTIVITY The fastest uncapped internet if fibre doesn't reach you. Rain's top plan measured 652Mbps peak at R1,199, MTN AirFibre hits 300Mbps, and Axxess fixed-5G runs R379 to R999. Entry plans throttle to 2Mbps after 150GB. Signal: Read the fair-use policy before the headline speed. That's where these plans actually live.
SAFE AND SOUND You can renew your ID at Capitec now. Smart ID and passport services are live at 242 branches. No Home Affairs queue. Signal: Worth knowing before your next renewal, whatever you bank with.
AUTOMATION ChatGPT can now study your writing and copy it. It'll read samples you feed it and imitate your voice. Signal: Useful for your admin emails. Less useful for anything anyone should trust came from you.
WORK AND PLAY Instant film is back and it costs R1,750. The Instax Mini 13 has landed locally with a few upgrades. Signal: Budget for film. That's where they get you.
WORTH IT?
Acconet Mini UPS, 48Wh
R264 at GeeWiz
BUY for a router and fibre box. WAIT if you've got a whole rack.
R264 keeps your router and fibre box online through an outage. That's the whole pitch, and at that price it's the cheapest useful thing you’ll see today. 48Wh lithium battery, 30W continuous output, and 5V, 9V and 12V outputs, so it fits basically any router or ONT power brick. Switchover is automatic and instant, so nothing reboots.
Two catches: It sits in line with a 12V 2A or better power supply, so check what your router came with. And 30W covers your router and fibre box, or a small indoor camera, but not all three plus a switch. Bigger stack, and you're looking at a proper power station instead, at ten times the money.
THE FIX
Your speed test is fast but Netflix still buffers
A great speed test number proves one thing: that for a few seconds, under test conditions, your line could move data that fast. But it says nothing about a full house of devices. And buffering isn't actually caused by a lack of peak speed; it's caused by the floor.
01 Plug a laptop into the router with a cable and test again. If wired is fine and Wi-Fi isn't, the problem is inside your house. Stop phoning your ISP.
02 Run a test while the buffering is happening, not afterwards, and watch latency rather than download. Consistently over 100ms is your culprit.
03 Change your DNS to 1.1.1.1 or 8.8.8.8 in the router settings, in both the WAN and the LAN DHCP fields. One DNS change took lookups under 30ms and the buffering stopped.
ONE AUTOMATION
Keep the house online when the fibre dies
WHEN the fibre connection drops
THEN switch to the backup LTE SIM
AND send you a notification
Most decent routers made in the last few years can hold a data SIM as a backup and fail over on their own. Cameras stay up, the alarm keeps reporting, and the person on a work call doesn't lose the meeting.
Set the SIM as a secondary WAN, turn on automatic failover, then pull the fibre cable out to test it. If it doesn't switch inside 30 seconds, your failover isn't configured; it's just sitting there.
Use a cheap data-only SIM and set a monthly cap on it, because a failover you forgot about can quietly chew through a bundle. Ten minutes in the router settings, once.
THE LIST
4 Deals to consider this week
Item | Where | Price |
|---|---|---|
JBL Tour One M3 ANC over-ears | iStore | R2,999 |
Sonoff NSPanel Pro 120 control panel | Takealot | R2,599 |
Maxdorf smart projector, Google certified | HiFi Corp | R6,499 |
Skyworth 65" Mini LED Google TV | House & Home | R9,499 |
Two are worth a closer look: the JBL headphones are half price, and at 70 hours of playback it's a flagship, not a clearance model. And the Sonoff panel is normally R4,809 down to R4002 with 4—6-day delivery, but look carefully: there’s an option where it’s only R2,599 if you pick 5—7-day delivery, so the wait is worth R2,210.
