It’s Time We Had A Chat About Router Channels

Granted, router settings aren’t the sexiest of topics. But when you consider the merriment that a router in good working order can bring to your life, you soon discover that spending a few minutes reading something turgid on the subject is probably worthwhile.

Channels are signal bands that different devices use to connect to your router to tell it that they are there. Your laptop might link to your router on one channel, while dear old Amazon Alexa might on another.

Most routers have three independent, non-overlapping channels that don’t interfere with each other, 1, 6, and 11. Devices transmitting on these channels will, therefore, carry on communicating to your router, oblivious to the fact that other devices are also sending information too. That’s what you want.

Channel Setting Problems

The problem comes when the automatic settings on your router lead several devices to connect to it using the same bandwidth. Two or three is usually okay, but the more devices you add to a particular channel, the less stable your connection. In the worst case scenario, some devices won’t connect at all while others are in use on the same channel.

Rather than spending hours fiddling around with internet settings and getting nowhere, it usually pays to go into your router settings and look at which devices are connecting on which channels. If you find that you have a bunch of devices all running through channel 6, then consider moving some of them to 1 and some to 11. Doing that will help to spread the load, reduce interference and, hopefully, restore reliable internet connectivity.

Neighbouring Networks

Okay, here’s where things get a little trickier. Even though the data being sent by neighbouring networks is encrypted, and even though you can’t use their router to send and receive data to the internet without a key, their signals can still interfere with yours.

People who live in flats, for instance, often find that their internet connections are unstable. Blaming the overall internet speed probably isn’t correct, but blaming your neighbours might be. Signals from your neighbour’s devices interfere with your own, causing your channels to become thick with interference, leading to dropped internet connections.

So what can you do about it?

You’ve generally got two options: you can either spend hours manually conducting experiments to see which channels work and which don’t, or you can use special programmes that automatically scan current channel usage in your vicinity and then tell you the optimal one to pick.

When boffins came up with the modern router, they didn’t envision just how many different signals would have to cram into such as small space on the electromagnetic spectrum (used for WiFi). But as the proliferation of devices continued, and more people used high-bandwidth broadband, people are going to have to learn much more about channels, including how to troubleshoot problems.

Knowing about channels can save you potentially hours wasted looking for a solution in the bowels of Windows 10 network settings and simple deal with the problem on the router itself.

Gadget Man Episode 128 – The World Wide Web turns 30!!

It only seems like yesterday when I was talking about the World Wide Web turning 25 years old and now before we know it, it’s now 30 years since the first HTML web page was authored and published by Sir Tim Berners-Lee.

The Web is, without doubt, the greatest invention of all time. It has made our planet smaller, brought together people from all walks of life and from every corner of the globe. It has made the world a much more accessible place, we can reach out to our idols and they can communicate back to us. We can transverse the globe and watch sunrises on opposite sides of the planet as they happen.

It truly is a modern wonder of the world. Cheers, Sir Tim!!

To find out how CERN is celebrating, visit the World Wide Web at 30.

With the wonders of the web brings ‘Smart Assistants’, they are on our phones, computers and now independently as ‘Smart Speakers’, another true wonder borne from the internet, serving our every need and answering the answerable. These ubiquitous electronic pucks offer a gateway to enormous artificial intelligence-driven knowledgebases that are themselves learning as well learn from us, Machine Learning is driven by millions of users.

Of course, every now and then our assistants flicker or make strange noises, we might wonder if these are simply glitches or the first sparks of self-awareness?

I spoke to Mark Murphy at BBC Radio Suffolk about both Smart Speakers and the 30th Anniversary of the Web. Listen in above and don’t forget to LIKE, SHARE and SUBSCRIBE. See you next time!!

Gadget Man – Episode 125 – What to do if you are involved in a car chase

Some 30 years ago, I was inexplicably drawn into a high-speed car chase across my home town of Hitchin.

When I left The Bird in Hand in Gosmore on that rainy night in 1987, I had no idea that the following 10 or so minutes would stay with me until now.

In my case, I managed to ‘lose my tail’, but it has always troubled me how the Police would have viewed my plight at the time. Back then, we didn’t have mobile phones in order to call the authorities, so I took it upon myself to try and outrun my potential assailant. If the same had happened now, I would have driven to the nearest Police Station whilst calling them on the way.

Now, thirty-two years later, I have my answer (sort of), in the form of a Police Inspector from Suffolk.

Gadget Man – Episode 124 – Keyless Car Theft Explained and How to Stop it

How many of us own and drive a vehicle with a keyless entry system? Well, it appears that many thousands of us that do have woken up this morning to a very worrying report from the General German Automobile Club (ADAC),

In order to unlock your keyless entry vehicle, you simply need to carry your key-fob. As you approach the vehicle, it recognises the encrypted signal transmitted from the fob. This, in turn, instructs the vehicles central-locking system to unlock the doors when you either touch the door handle or press the button on the door-handle. There is no requirement to insert the key into the ignition as the car is fitted with a start/stop button. If you own a car with both keyless entry and start/stop system, you aren’t alone, they are now widely used in hundreds of models or cars and in some cases motorbikes.

Now for the bad news. A recent study by the General German Automobile Club (ADAC) has discovered that the technology is far from secure in all but THREE cases and in fact the method of stealing a keyless vehicle is extremely simple.

In order to steal a keyless vehicle, a thief simply employs a rudimentary transceiver which takes the relatively weak signal transmitted and received from the fob to the car and amplifies it, it is then possible for the signal to reach from the fob to the car and hey presto, the car is unlocked and can (in most cases) be started.

[videopress VxMJuooi]

Once the car is running, the need for a key is obsoleted and the car can now be driven until it is depleted of fuel. In most cases, the cars are taken abroad and the retrofitted with standard locking and start systems. As long as the car does not stall, it will run for as long as the fuel tank will take it.

NO AMOUNT of hacking or decryption is needed, it is reliant solely on the amplification of the already transmitted signal!

Arnulf Thiemel, car-technician at the ADAC, said “The ADAC demands that vehicles be protected against any kind of manipulation and illegal access. For the affected vehicles, there must be solutions put in place to improve the security.  All new  vehicles should also be equipped with a methodologically that ensures secure safety solutions which also withstands neutral side checks”

Which cars and manufacturers were affected?

Unfortunately, it would appear that EVERY manufacturer tested has at least one model which could be stolen using the method above.

Alfa Romeo, Audi, BMW, Chevrolet, Citroen, DS Automobiles, Fiat, Ford, Honda, Hyundai, Infiniti, Jaguar, Jeep, KIA, Land Rover, Lexus, Mazda, Mercedes, MINI, Mitsubishi, Nissan, Opel, Peugeot, Renault, Seat, Skoda, SsangYong, Suzuki, Subaru, Tesla, Toyota, Volvo, Volkswagen and motorcycles from BMW, Ducati and KTM. 

The following vehicles could NOT be opened using this method but if already open it was STILL POSSIBLE to start and drive the cars.

BMW i3 (2014)
Infiniti Q30 (2016)
Mazda 2 Skyactive 90 Kizohu (2018)
Volvo XC60 T5 (2017)

The following vehicles could NOT be opened or started using this method.

Jaguar i-Pace (2018)
Land Rover Discovery (2018)
Land Rover Range Rover (2018)

The vehicles above are currently immune from this method of attack. This is because they employ a variation of the keyless system by broadcasting using ultra-wideband frequencies. Basically, the equipment used to amplify the signal is ‘currently’ unable transmit or receive at the radio frequencies used in these models of cars.

Jaguar-Land Rover filed the patent for this method of keyless access in 2017. We can now only hope that they freely license these patents to other car makers or a comparable technology can be developed.

What Now?

All too often our deep-rooted human needs to be ‘waited upon’ result in solutions which in the first instance appear to solve a problem that really didn’t exist, but in real-world use turn out to have a sting in the tail. In the case of the study by ADAC, it would appear that there are very urgent questions to answer and drivers should be aware of the security issues surrounding their vehicles.

Faraday Cases?

Prior to speaking to BBC Radio Suffolk, many listeners talked about using Faraday Cases or Bags to house their keys. The theory behind this was to block the signal completely whilst the car isn’t in use (ie. whilst the keys were stored in the home or place of work).

Faraday Bag for Keyless Fobs from Amazon

I personally believe that keeping the keys away from the car or placing them in a container which COMPLETELY blocks radio signals is the only way to avoid the potential theft of vehicles using this method. However, radio signals can travel through types of metal, so be ABSOLUTELY confident that anything you purchase to secure your fobs, does indeed work as described.

Immediate Steps to Take

If you are concerned about the security of your keyless car fob, contact your car’s manufacturer as soon as possible and ask them what steps they have taken to secure your car? Ask them if there are software updates to improve security? Ask them if these systems can be deactivated until such time as they can be completely secure?

Gadget Man – Episode 123 – The Demise of the Yellow Pages

Earlier in the week, I spoke to Mark Murphy on BBC Radio Suffolk about the demise of the Yellow Pages directory.

The Yellow Pages was always sat alongside the equally large Phone Book, but had gradually declined over the years since the introduction of the Internet and increasing dominance of search engines such as Google which has made searching for and finding businesses much easier and informative.

Having rebranded as Yell.com many years back and diversifying it’s business interests as an ‘Internet’ brand, the directory has had a long and some might say “painful” death. In the way the Phone Book died in part due to privacy concerns, the Yellow Pages has died due to lack of interest. In our fast-moving world, there is no longer a place for archaic, expensive and out of touch printed directories. The internet now provides so much more. We will just need to find something else to keep the kitchen table from rocking!

Gadget Man – Episode 122 – Are We Influenced By Movies And Media?

Last week, I spoke with James Hazell on BBC Radio Suffolk about the new film classifications and how they can be applied to online video streaming sites.

I also discussed YouTube’s ban on videos that contain or encourage dangerous pranks that endanger people or could cause harm to people copying them.

BBFC Ratings
BBFC has revised it’s classifications

Following a public consultancy of more than 10,000 people, the BBFC (British Board of Film Classification) has now revised its classifications to make it more consistent across platforms, including online services.

David Austin, Chief Executive Officer at the BBFC, said: “Over the last five years the way we consume film and video has changed beyond all recognition. That’s why it’s so important that there is consistency between what people watch on and offline.  The research shows that parents and teenagers want us to give them the information and guidance that they need to view what’s right for them.

We’re here to listen to what people want, which is why they trust our age ratings.  So it’s encouraging to know that we’ve been classifying content in line with what people want and expect when it comes to difficult themes around credible real life scenarios. We also know that people are more comfortable with issues such as action violence, if it’s in a way that they are expecting – such as a Bond or Bourne film. We are updating our standards around depictions of sexual violence and very strong sex references to reflect changes in public attitudes.”

In discussing YouTube enforcing rules banning videos which either put people in danger or promoted acts which might lead people copying those acts to either suffer harm or place others in danger, we discussed recent movies such as the Netflix production; Birdbox which led some people to challenge others to go about day-to-day activities whilst blindfolded and may have led a driver in the US to become involved in a motor vehicle accident.

Gadget Man – Episode 121 – Too Much Smartphone Part III

As we enter the final year of the second decade of the 21st century, the smartphone will surely be considered the most revolutionary gadget of the last 10 years.

Our phones are now firmly ingrained in our lives, joining us at home, at work, at play, at the dinner table, in bed, they come with us everywhere! Our lives are documented in detail, where we go, what we do, what we think and what we eat. We’ve now become news gatherers, critics and voyeurs all without realising it was happening in front of us.

Too Much Smartphone III
Too Much Smartphone III

The use of mobile phones stretches to every age group, from the elderly to the very young and with this comes concern as to the use of these devices. Should young people be allowed to use their phones at any time of the day OR night? Does it reduce conversation? Are we become LESS social?

I have now covered this subject twice in the past, you can read a listen in here and here, however now reports are informing us that phones DON’T cause our children harm, listen in to the podcast, where I talk to Mark Murphy on BBC Radio Suffolk about this latest contentious report.

The Gadget Man – Episode 120 – The Resurgence of the Cassette

As the new year dawns, we again look back, but this time it’s more than 30 years to yet another audio format resurgence. Now that Vinyl has once again become freely available to the masses after being all but condemned by CD’s, MP3’s and then streaming music, another format becomes the trend of choice. Yes, we are now being encouraged to revisit the Cassette Tape! Another Hipster trend or is there more to it?


HEAD’S UP!! You can listen in to me talking on BBC Radio Suffolk with Mark Murphy about my memories of cassette tapes, don’t forget to Like, Share, Subscribe or Listen directly.


For me, it’s difficult to understand how revisiting this format has any real appeal. The audio quality was mediocre, to say the least. Unless of course, you could afford $2,500  ($5000 in today’s money) for a Nakamichi Dragon Cassette Deck which in 1991 was widely considered to provide the best audio reproduction available.

For those of us unfortunate enough to be devoid of 5000 bucks, we instead looked at more portable alternatives, either in the shape of your unfriendly neighbourhood ‘Ghetto Blaster’ or the even smaller ‘Sony Walkman’. Whilst our aspirations for these two devices may have been the popular ‘break dancing’ movies of the era, we would have to face up to lesser versions of both.

Ghetto-Blaster or Boom-Box

The giant Ghetto-Blasters we dreamed of with 20 D-Size batteries, would, in fact, end up with less bulky and much less ‘blasting’ boom-boxes.

The incredibly sleek Sony Walkman’s would also be too expensive and thus instead we ‘made-do’ with cheaper and much poorer alternatives featuring tinny headphones and literally all DSP (digital signal processing) technology removed to either keep down costs or avoid licensing fees being paid by the manufacturers.

Tape Cassettes did launch the car and personal stereo experiences,  which went on to launch the digital experience that we all enjoy today. So just for this alone, we should be thankful. It does not, however, mean that cassette tapes sound any better than anything else that is currently available. We now don’t need to arduously fast-forward or rewind to our favourite tracks and we most certainly do not have to spend hours fiddling around with pencils to re-tension cassettes, it’s now so much easier. So maybe they should stay consigned to charity shops and eBay.

The Gadget Man – Episode 119 – Technology to look out for in 2019

Another year passes and as we move into 2019 we can look forward to another year of unstoppable advances in technology.

If I was able to predict upcoming tech, I’m happy to suggest that my number one for 2019 will be the folding mobile phone with potential devices from LG and Samsung already breaking cover in various forms.

[videopress WcnyB1iG hd=”true” autoplay=”true”]

Both companies have already demonstrated their flexible display technologies and with the Mobile World Congress in February coming up soon, we should expect demonstrations of foldable, rollable or bendable screen tech from these companies.

Artificial intelligence is sure to continue its unstoppable march towards self-awareness (I jest!!), but all the same, we should be seeing multi AI ‘bots’ training directly with each other very soon! Who could forget the Facebook AI bots which invented their own communication language shortly after being switched on! More of this in inevitable, hopefully with the necessary safeguards in place.

The big 3 tech companies continue to advance home-based smart technology with integration into every part of our lives, add to this more AI and who knows what we should expect from the likes of Amazon, Google and Apple.

Holograms are a little way off, but augmented reality is making leaps and bounds with more advanced filters on spectacles providing with illusionary-holographic images a reality soon.

Phone batteries continue to provide us with more and more screen time and further advances in battery and charge technology will give us even more excuse to distract ourselves on a daily basis.

[videopress eFz5BDAp]

This year we look forward to the beginnings of the 5G roll-outs, giving us impossibly fast download speeds, but also extending decent internet speeds to rural areas of the UK.

Ultimately, we are not about to be overrun by killer robots and 2019 will be bringing some pretty astounding new technology, strap yourselves in and enjoy the ride.

I talked on air with James Hazell from BBC Radio Suffolk about my predictions for the coming year. Have a listen and don’t forget to  Like, Subscribe, Share and Comment and I will see you very soon.

Staying on Top of Tech: Is The Newest Really Worth it?

Those of us who love new tech gadgets will, undoubtedly, feel a bit gutted when we see the price of the latest releases. Sure, someone will always be able to afford it and can flaunt their newest gadgets around while the rest of us watch in envy – but is it really any point in always buying the latest?

Image by: Pexels

Here is a quick guide to those who would love to pre-order every new smartphone each year but who, sadly, will need to wait for the price to drop a bit. It just makes it a bit easier to stay on top of the latest tech even if you can’t afford it – and it may even take those expensive gadgets off your mind for a bit.

It won’t make you rich overnight, that’s for sure, but at least you’ll be able to enjoy the tech you already have and perhaps even afford the newest ones if you know where to look.

First: You’ll often get what you pay for

When it comes to technology, the newest does tend to be better than the gadgets we were playing with a year or two ago. The world is constantly evolving, after all, and we will be able to enjoy more powerful software and slicker-looking hardware; the difference may not always be that huge but it should be an improvement with each passing year unless we’ve started to go backwards again.

This doesn’t mean that an upgrade to the absolute latest is always worth the money, though. If you have been using an iPhone X, for example, and can’t stop thinking about the iPhone XS, you might want to hold on for a while before buying it as the difference isn’t really that big – going from an iPhone 7 to an iPhone XS, on the other hand, will definitely be noticeable.

Consider the technology you already have and whether or not it’s actually as outdated as you think it is before you head out to buy something that’s still slightly overpriced.

Next: Look for better deals

Those who enjoy saving money and would like to have a bit more of it to spend on other tech gadgets know that good deals can be hard to come by. Some of them may even just be incorporated in your phone deal and you can’t really take advantage of it unless you already have it – while others are hidden around the web instead.

Start by having a look at this, to begin with, and consider if a later version of a refurbished phone is right for you rather than paying half a paycheck on a brand new smartphone. This might not be for everyone but it can definitely help you to get the latest tech if you really want it.

Finally, it’s also a good idea to keep in mind that some technology can be bought a bit cheaper without compromising its quality. While smartphones are not one of them, you may be able to get a high-quality Bluetooth speaker without pawning your most valuable belongings first.

When it comes to excellent tech gadgets, waiting for the price to drop is definitely the best way to go if you’d like to save money. Prioritise what you need to have right away and what you can wait for, in other words, and you might be able to avoid the temptation of every new deal out there.
