Wi-Fi & connectivity
Connectivity faults are the most over-diagnosed problem in television repair. A great many are network, firmware or settings issues that cost nothing in parts — and we check all of those before we suggest a Wi-Fi module.
It is worth stating plainly: when a smart TV will not connect, the television is frequently working exactly as designed. The router is at the other end of the house behind two brick walls. The 5GHz band does not reach. The DNS settings are wrong. The router has too many devices on it. The firmware is out of date and can no longer negotiate with a modern network.
None of that is a hardware fault, and none of it should cost you a Wi-Fi module. We test the network as seriously as we test the television, because sending a technician to replace a perfectly good component is not a service, it is a waste of your money.
That said, Wi-Fi modules and their antennas genuinely do fail — Highveld dust and heat both take a toll on them over the years. When that is the fault, we can replace them. We simply prove it first.
The detail
Software, network, or hardware — in that order of likelihood.
If the television sees no networks whatsoever, that is a stronger indicator of a hardware fault — a failed Wi-Fi module or a disconnected antenna. If it sees other networks but not yours, the problem is very likely the router or the band.
Usually signal strength, channel congestion, or a router aggressively dropping idle devices. Sometimes a firmware bug. Rarely a hardware fault, though a degraded antenna will do it.
This is not a connectivity fault at all — it is a DNS, certificate or firmware problem. Older smart TVs eventually lose the ability to negotiate modern security certificates, and streaming apps simply stop working.
Typically insufficient memory, a corrupted app cache or an out-of-date firmware image. A cache clear and a firmware update resolve a good proportion of these.
Frustratingly common. App providers drop support for older platforms. Sometimes a firmware update restores it; sometimes the honest answer is that a streaming stick is a far cheaper solution than a new television.
That is a strong indication of a Wi-Fi module or antenna fault, and it is one of the clearest diagnostic signals we get. It is repairable.
What you get
Free fixes first. Always.
01
Signal strength, band, channel and router behaviour.
02
Often the entire fix, and it costs nothing in parts.
03
The invisible cause of ‘connected but nothing loads’.
04
Cheap, quick and frequently effective.
05
When it genuinely is hardware, we replace it.
06
Sometimes a R700 streaming stick beats a R3 000 repair. We will say so.
Included
The television and the network it lives on.
Wi-Fi signal strength at the TVMeasured where the set actually is, not at the router
Band and channel analysis2.4GHz versus 5GHz, and congestion checks
Router and DHCP behaviourBecause the router is very often the culprit
Firmware version and updateBrought current where the manufacturer still supports it
App platform testingNetflix, YouTube, Showmax, DStv Stream and Prime
Wi-Fi module hardware testWhere the software route is exhausted
Our process
01
Does it see the network? Connect and drop? Connect but not load?
02
Because the television is frequently innocent.
03
Firmware, DNS, cache, re-pairing — all free of parts cost.
04
And we will show you why before we do it.
FAQ
The things people actually ask us on the phone, answered straight.
WhatsApp us the make, the screen size and a short video of what the TV is doing. We can usually narrow the fault down before a technician is even dispatched.
WhatsApp 063 866 0971Possibly, but it is not where we would start. If the television can see other networks but not yours, the issue is almost certainly your router, the band or signal strength — not the TV. If the television cannot see any networks at all, then a hardware fault becomes much more likely.
That is a DNS or security-certificate problem, not a connectivity problem. Older smart TVs eventually lose the ability to negotiate modern encryption standards, and apps stop loading even though the network connection is perfectly fine. A firmware update sometimes fixes it.
Sometimes. If the app provider has dropped support for your television’s platform — and they do, on older sets — then no amount of repair will bring it back. In that case a streaming stick costs a fraction of a new television and gives you a fully current app platform. We will tell you honestly which situation you are in.
Almost always, yes, if you can run the cable. Ethernet is more stable, faster and immune to the interference and congestion that plague Wi-Fi. If your television is close enough to the router, it is worth doing.
The module itself is generally replaced rather than repaired, and it is not usually expensive. Antenna connections, which fail more often than the module, can frequently be repaired — and a loose antenna connection is a far more common cause than a dead module.
Almost certainly not. A streaming device gives an older television a fully modern smart platform for a small fraction of the cost of replacing the set. If the panel and the picture are still good, replacing the whole television because of an app is poor value.
