Are Christmas angel lights unequivocally ruining your Wi-Fi?

The UK’s telecoms regulator Ofcom has warned that Christmas lights can delayed down your Wi-Fi, yet is it unequivocally time for those lights to stay in a box?

Are angel lights causing my Wi-Fi to delayed down?

Yes, yet … and it’s a large yet …

But, discordant to what a Christmas naysayers among us competence say, no some-more so than all else. The Wi-Fi vigilance can be disrupted by anything that causes division as it is promote around your house. Fairy lights can means some interference, yet they’re distant from a misfortune offender.

Why do angel lights means interference?

It’s all to do with electromagnetic radiation. Everything from light to x-ray ovens and low space radios use electromagnetic waves possibly to lift information or to explain energy.

Wi-Fi uses electromagnetic waves to send information to and from your broadband router and your mobile device or computer.

But all that has electricity regulating by it also generates an electromagnetic field, and this causes division to a electromagnetic waves attempting to transport by it.

Fairy lights are a mass of wires carrying a stream that creates a little electromagnetic margin and so a small interference.

What else causes interference?

Most things, if placed between your device and your router, can means interference. But some are a lot worse than others. Here’s a discerning (not exhaustive) list:

Terrible

  • Microwave ovens – when it’s off it’s a steel box (which is bad), yet when it is on it uses high-powered microwaves during around 2.4GHz in (the same magnitude as Wi-Fi) formulating a black hole around it for Wi-Fi signals

Really bad

  • Radiators, fridges, freezers, toasters, kettles, soaking machines, decrease driers, dishwashers, ovens, AGAs (one for a posher readers there), steel baths – and computers themselves – are all steel objects and mostly have liquid-containing pipes in them
  • Water pipes – H2O loves radio waves, a H2O absorbs a appetite from them
  • Cordless telephones – DECT phones use a same frequencies as Wi-Fi and are mostly unfortunately placed subsequent to a router
  • Other people’s Wi-Fi networks – depending on your router’s chain in propinquity to other people’s routers, this can be a really large problem (more on that later)

Bad

  • Humans – people are good during interesting Wi-Fi
  • Insulation – a same unenlightened things that keeps feverishness in a walls and ceilings also causes issues for Wi-Fi
  • TV – routinely not a large emanate unless we place your router behind it
  • Speakers – fundamentally electromagnets so can means interference
  • Fairy lights – can emanate diseased electromagnetic fields

Good

  • Christmas tree – a tree is not unenlightened adequate to means a genuine issue
  • Light upholstery – many sofas, beds and other seat is not really unenlightened and causes small emanate for Wi-Fi
  • Pets – unless we possess a bear, they’re substantially not large adequate to means issues unless they lay directly on a router

Why do so many things means problems?

The electromagnetic spectrum, from radio waves to gamma rays and all inbetween.
electromagnetic spectrum

That so many things means division between routers and your mobile inclination is in partial interjection to a spectrum Wi-Fi uses being partial of a unlawful ISM band. That means many other non-Wi-Fi inclination also use frequencies identical to 2.4GHz and 5GHz , so causing interference.

A digital cordless telephone, for example, typically uses frequencies between 1.8GHz and 1.9GHz, that is utterly tighten to a 2.4GHz rope used by Wi-Fi.

But it isn’t usually inclination regulating some arrange of radio communications that means issues for Wi-Fi. The vigilance can usually dig so distant by plain objects before it loses appetite and is no longer useful, that is since carrying some-more walls between we and your router means we get a weaker signal.

Does it matter what they’re done of?

Some materials catch or inhibit Wi-Fi improved than others. A steel fridge, for instance, is really formidable for radio waves to penetrate. Water is also a fanciful Wi-Fi sponge, definition H2O pipes make glorious Wi-Fi vigilance blockers, quite when placed corresponding with other H2O pipes as is routinely a box in walls and floors.

What can we do about it?

Reducing division typically means possibly stealing a intent or relocating it out of a trail of your Wi-Fi signal, yet there are alternatives.

If we consider of your Wi-Fi router as a mill thrown into a pond, examination a ripples generate from a indicate of impact with a H2O we get a good thought of how your router works.

On a really simple spin it broadcasts your Wi-Fi vigilance in all directions during once. Like another stone in a pool that blocks those propagating ripples from going any further, anything that gets in a approach will means reduced Wi-Fi vigilance strength behind it.

Wi-Fi, of course, travels by objects, yet during a cost of appetite that means reduce vigilance a other side.

Some newer routers can map out division spots and boost vigilance strength in that instruction to try to overcome a passed zone.

Where should we place my router?

The best place to put your router for a best probable Wi-Fi coverage is in a center of your home. If we have some-more than one floor, ascent it as tighten to or on a roof will also assistance cover both downstairs and upstairs.

Placing it in a ideal mark isn’t always practical, quite given that a ADSL or wire typically comes in during a front or behind of your residence or flat, and routing cables to a improved place for a router can be a nightmare.

You should equivocate putting your router within tighten vicinity to other electrical products such as on tip of a games console or behind a TV or stereo for instance.

Any disproportion between dial-up, ADSL and cable?

The speed of your line entrance in creates small disproportion to your Wi-Fi speed, other than capping a limit internet speed we can receive. If your broadband line is usually 5Mbps, a limit speed from a internet we will ever get, no matter how good your Wi-Fi setup is, will be 5Mbps. It will not impact transfers between computers on a same Wi-Fi network, for instance.

It’s value observant that a length and peculiarity of a cables entrance into your skill from your broadband provider can make a large disproportion on your broadband speed.

The shorter and aloft peculiarity a wiring into your residence a faster a probable speed. It isn’t routinely an emanate unless we have old, bad peculiarity phone line wiring within your house.

It is improved to run ethernet wire from your modem to a apart router than run prolonged phone cables.

Does it matter what router we have?

Yes. Routers are little computers that increasingly hoop a lot of information and high speed. Like any other electrical product we get what we compensate for.

Spending hundreds of pounds isn’t necessary, yet not all routers are innate equally. More modernized routers ancillary newer Wi-Fi technologies can offer poignant vigilance and speed boosts.

Is there some-more than one Wi-Fi technology?

Wi-Fi is a code name for a wireless networking custom 802.11. It comes in several versions, any one an alleviation on an comparison system.

The initial chronicle of 802.11 was expelled in 1997 and reached a limit speed of 2Mbps regulating a 2.4GHz band. In 1999, 802.11b increased speeds to 11Mbps on 2.4GHz, while 802.11a charity 54Mbps regulating a aloft magnitude of 5GHz. 802.11g was expelled in 2003 brining speeds adult to a limit of 54Mbps on a 2.4GHz band.

The conditions was simplified in 2009 with 802.11n, that lonesome both 2.4 and 5GHz magnitude bands, charity larger insurgency to division and speeds of adult to 600Mbps per connection.

The latest widely accessible customary is 802.11ac, mostly created as Wi-Fiac, that is a many strong complement to date and offers mixed connectors between a router and a singular device, reaching limit speeds of 1Gbps – one thousand times faster than a initial chronicle of Wi-Fi.

It’s value observant a limit speeds are frequency ever reached, even when your broadband tie to a outward universe is not a tying factor.

Does it matter if you’re super tighten to others?

Yes, one of a biggest problems for complicated Wi-Fi homes is a overlapping of other Wi-Fi networks from surrounding homes. The conditions is done worse since as division increases from other networks your router ups a promote energy stretching serve into others’ homes, causing their router to try harder and in spin formulating some-more division for your router.

Is there anything we can do?

The best probable unfolding would be to spin your home into a hulk Faraday cage, that would retard signals from entrance in and your Wi-Fi from leaking out. But it would also retard other signals such as FM radio, your mobile phone, indoor TV accepting etc.

Your router can be adjusted, and competence do it automatically for you, to assistance stop interference. Wi-Fi is typically promote opposite 13 opposite channels, nonetheless it isn’t a same in each country.

By changing a channel that is used by your home Wi-Fi network we can assistance lessen division from other surrounding Wi-Fi networks. Any dual channels apart by 5 or some-more do not overlap.

In a UK and US that means that channels 1, 6 and 11 are a usually organisation of 3 non-overlapping channels. Switching to one of them competence assistance your Wi-Fi network, yet many complicated routers regulating a latest Wi-Fi standards have programmed systems to switch between channels to equivocate interference.

And finally, what about devices?

It’s also value observant that Wi-Fi is a two-way street. The device you’re joining to your router is only as important. Older smartphones, tablets and computers competence not support newer versions of Wi-Fi, for instance.

Some Wi-Fi connected inclination such as radios or games consoles also do not support 5GHz Wi-Fi networks, that are mostly used to equivocate interference.
