10 reasons why your Wi Fi is so slow and how to fix it

10 reasons why your Wi Fi is so slow and how to fix it


wifi

Wi-Fi is the way of the world now. It is the invisible friend who comforts us, allows us to rock on Netflix in bed, and equips us to work from anywhere at any time. Wi-Fi is pretty much a necessity these days. Sometimes, however, the relationship becomes sour - especially when Wi-Fi slows down at a pace. When you depend on Wi-Fi, speed problems can be harmful. Unfortunately, speed issues are not always easy to diagnose due to Wi-Fi operation. An unknown variable could potentially reduce your Wi-Fi speed in half, so its important to know what to look for when something goes wrong not. Knowing this, we can now explore some of the lesser-known reasons why your Wi-Fi is so slow - and the best ways to solve these problems.


Router_positioning_High_low
1. Router positioning: High vs low

Most people underestimate the importance of choosing a good place for a Wi-Fi router. Even a small change in positioning could end up being the difference between day and night.

If you are like most people, you probably unpacked your new router, located at the exit of the reasonable location, plugged in, and simply left on everything that was nearby: a shelf, desk, or even floor. As it stands, the routers height makes a difference.

This means that your router leaving on the ground or other objects behind usually results in significantly worse performance. Instead, put the router as high as possible to extend the range of broadcast waves. This also makes it possible to remove the router from possible interferences.

2. Router positioning: Concrete & metals

Materials such as concrete and metal tend to be the worst for blocking Wi-Fi waves, but even objects from other materials can hinder the high wireless performance. Make sure that your router is not blocked by other objects, especially electronic devices.

Also, avoid placing your router in your basement as this area is usually surrounded by a lot of concrete, which can be almost impossible for Wi-Fi signals to penetrate.

3. Router positioning: Distance to router

The further away you are from your router, the lower the Wi-Fi signal. Therefore, the best option is to place your router as close to your devices as possible, but this is only convenient if you have a main area where you tend to use your devices.

Otherwise, you should place your router near the center of your house. After all, Wi-Fi broadcasts 360 degrees, so it does not make sense to put it at one end of the house.

However, if your router is particularly weak or your home is particularly large, you may need to increase the range of these Wi-Fi waves by using Wi-Fi extensions or repeaters. These are auxiliary devices that connect to the Wi-Fi network. Router and "repeat" the signal so that it covers more surface.

If you want to get really scientific on your router site, take a look at this project from a doctoral student and download the application to try it out for yourself.

4. Wireless interference & noise

You probably have never noticed, but there are wireless signals everywhere you go and they go through you all the time. From where? Electronic devices, Wi-Fi routers, satellites, cellular towers, etc.

Information designer Richard Vijgen has created "The Architecture of Radio" - available on iOS and Android - that uses public information on satellites and cell towers, as well as Wi-Fi information, to create a map of All the invisible signals around you. I tried this out and you can see the results of my essay in the screenshot above.

Although Wi-Fi is assumed to be on a different frequency than most of these devices, the amount of radio noise may still cause interference.

5. Microwaves can cause interference

Did you know that microwave ovens can cause interference with your Wi-Fi network? Especially with older routers. This is because microwave ovens operate at a frequency of 2.45 GHz, which is incredibly close to the 2.4 GHz Wi-Fi band.

Specifically, the 2.4 GHz Wi-Fi band actually broadcasts between 2.412 GHz and 2.472 GHz, there are times when the frequency of microwaves can overlap with the Wi-Fi frequency - and when this occurs, Transferred data is disrupted.

Most microwaves are properly protected so that no waves should be detected outside the oven, but when there is a faulty or bad shield, this is where interference may occur.


6. Wireless interference: Bluetooth devices

It turns out that another preferred type of wireless connection - Bluetooth - also happens to operate at 2.4 GHz. In theory, a properly designed device must be shielded in a manner that prevents interference.

In addition, in order to avoid the frequency clash, Bluetooth manufacturers use frequency hops, which is where the signal rotates randomly between 70 different channels, changing up to 1,600 times per second. Newer Bluetooth devices may also have the ability to identify "bad" or currently in use channels and avoid those.

But interference can still occur, so try to move the router away from Bluetooth devices (or at least turn them off) to see if this is the cause of your problems - especially if they are older Bluetooth devices without management channels.

Wireless_interference_Christmas_lights

7. Wireless interference: Christmas lights

Fairly funny, Christmas lights (or fairy lights) can be a misguided guilty by slowing down your Wi-Fi because these lights can emit an electromagnetic field that interacts with your Wi-Fi band. This is especially bad when you Use lights with the ability to blink.

You are not even safe with modern LED lights because some of them have flashing chips built into each lamp, and these create an interfering electromagnetic field.

In reality, all other types of lights can cause interference by emitting electromagnetic fields like this, but the effect is almost negligible in most cases. However, you must keep your router away from electric lights just in case.

Check_Channel_interference


8. Check for Channel interference

A modern world truth is that every household has its own Wi-Fi network, which can cause problems with channel overlap. This can be somewhat problematic in a townhouse but is particularly problematic in residential complexes and apartments where there may be a lot of routers nearby.

Channel overlap is mostly a problem for routers that can only broadcast at 2.4 GHz, or if you have devices that can not receive a 2.4 GHz wireless signal. Why? Because there are only 14 channels to broadcast on. Two routers broadcasting on the same channel at the same frequency will interfere.

This is why it is important that you choose a good channel in your router settings. Modern routers can automatically choose channels for you, but it is sometimes best to explore and find the best channel yourself.

In addition, people can try to get on your network without your knowledge, and this can also slow down your Wi-Fi. The most important thing you can do about this is to make sure your router does not A password easy to break. Also, keep your router up to date and perform regular checks on suspicious devices on your network.

Prioritize_network_traffic


9. Prioritize network traffic

Have you ever left a massive download running on your PC? Well, in this case, you are probably the cause of your own slow Wi-Fi. Downloading large files can take a long time on your Wi-Fi performance. Sometimes this can not be avoided - updates Of the operating system can be huge, for example - but if you are performing tasks that are not urgent, try to stop them.

More likely, however, is that people on your network - like friends, roommates or family members - participate in the bandwidth of heavy activities like Netflix games and streaming. Fortunately, if this is the case, you can prioritize your own network traffic by enabling quality of service in your router settings.

Water_can_slow_down_radio_waves


10. Bonus fact: Water can slow down radio waves

Humans are 60% water ... and water can slow down the radio waves. Although I do not suggest that you remove all people from your home, make sure your router is kept out of the main areas where people are gathering. The impact will not be terrible, but it could be noticeable.

7 reasons why THIS is the best time to be a Shah Rukh Khan fan

7 reasons why THIS is the best time to be a Shah Rukh Khan fan



Dear Zindagi continues to mesmerise viewers all over as the movie enters its second week. And for those who were ready to write Shah Rukh Khan after the disappointing performance of Dilwale and FAN, well, they will be eating their words now. Agreed that Dear Zindagi is no Sultan-like blockbuster, but it was never promoted in that way. For such a mass entertainer-like performance, wait for Raees that comes in January. Dear Zindagi can be SRK’s smallest film in years when it comes to the movie’s budget, and therefore the business it is making is enough for the movie to be called a success.


Well, if you thought as a SRK fan, you can be satisfied with how his latest film has met with such a glowing reception, you would be surprised to see Salman Khan unveil the first look of Shah Rukh Khan‘s untitled movie with Anushka Sharma on Twitter. As expected, both the promotional move as well as the poster got an overwhelming response. And just when we are yet to recover from the euphoria of seeing that poster, SRK pulls another trick card from his sleeve, as he released a special video announcement for the trailer of Raees, that’s coming out on December 7. The announcement video itself had some unseen scenes from Raees, that left us asking for more. Oh, why does December 7 feel so far away?


So with three things happening back to back with regards to King Khan and his movies, here’s why we feel it is the best time to be a Shah Rukh Khan fan. Statutory Warning: No Salman Khan fan was hurt while writing this piece.


At 51, SRK  is looking hotter than ever


1451981525-srk3


They say age is just a number. After watching SRK charm the audience with his bearded appearance, mesmerising twinkling eyes, and that dimpled smile playing Dr Jehangir Khan in DZ, we finally agree to that adage. Mr Khan does know how to age gracefully. Or is he even aging at all?


A movie, a first look and a trailer all together…what more do we want?


200 (1)


While we have to wait for days for our superstars to give us a proper update about their upcoming movies, Shah Rukh Khan has just unveiled the first look of his upcoming movie, while prepping us for the trailer of his other future project. This is when his movie has just released and is running successfully at the theatres. I mean, as a Shah Rukh Khan fan, what more do you want?


Dear Zindagi worked, didn’t it?


OCyOKYkMjldGo


As an SRK fan myself, I was terribly disappointed with how Dilwale and FAN, two very exciting movies for me, finally turned out to be. So it was expected that these two movie will underperform at the box office, and there were loud whispers that SRK is no longer the force majeure that he was before. However Dear Zindagi worked surprisingly, despite it being an Alia Bhatt movie and SRK being in a supporting role. Even though I am not completely impressed by the movie, DZ’s positive reception is enough to get us more excited about Raees. Speaking of which…


Finally we have something in Raees to give takkar to Sultan


daring_071715103909


Sultan is the biggest hit of 2016 (unless Dangal manages a coup), and it made nearly every Salman Khan fan happy with its masala elements. As for Shah Rukh Khan, FAN may have flopped, but Dear Zindagi is running successfully. But it is neither a mass entertainer nor has the potential to be competition to Sultan in any way. For that we have to wait for Raees. Going by the first teaser that came more than a year ago and its recent announcement video, Shah Rukh Khan has a potential blockbuster in hand that could take on Sultan’s BO business heads on. We are so excited for its release!


No longer Rahul, he is Jug, Miyanbhai and a dwarf


tumblr_nrl9yussFB1s88ak5o4_500


Shah Rukh Khan has often been accused of sticking to Rahul and Raj kinda roles by his detractors. Well, from 2016, you can never accuse him of doing so anymore. Even though FAN was a flop, it had SRK being a part of a movie where he does everything except romance. Dear Zindagi put him and Alia Bhatt in a frame, made us saw how good they look together but refrained from showing them as a romantic pair, which could be a first for an SRK movie. In Raees, he is a ganglord, Miyaanbhai, a man with grey shades, and you know SRK rocks in such characters. Even though his movie with Anushka Sharma is romantic in nature, it’s an Imtiaz Ali movie, so the romance will be very underrated here. And he is playing a freaking dwarf in Aanand L Rai’s next!


Imtiaz Ali and Aanand L Rai = 


ezgif.com-0f208fe61b


After pleasing his friends Farah Khan and Rohit Shetty by working in Happy New Year and Dilwale, SRk is now ready to work with new and exciting directors. While his attempt with Maneesh Sharma (FAN) may have gone awry, Gauri Shinde proved lucky for him. Now his upcoming movies are all directed by acclaimed directors – Raees with Rahul Dholakia (Parzania) and those untitled movies with Imtiaz Ali (Jab We Met, Rockstar, Highway) and Aanand L Rai (Tanu Weds Manu, Raanjhanaa).


Shah Rukh -Salman = Bhai Bhai


salman-srk1-7591


Both Salman and Shah Rukh have let go off their petty egos and have become good friends. Shah Rukh Khan rescheduled the release of Raees to avoid clash with Sultan. Both went cycling together, they promote each other’s movie, and now Salman has even unveiled the first look of SRK’s untitled movie with Imtiaz Ali. Now there are reports that they will host the next Star Screen Awards. So if these two stars can get along as good friends, why not their warring fans? Let the Bhaichara spread to the fan clubs as well. Or should we wait for Rakesh Roshan to announce Karan Arjun Phir Se?


So do you agree that now is the best time for being a Shah Rukh Khan fan?

3 big reasons why President Barack Obama will be remembered as ahead of his time

3 big reasons why President Barack Obama will be remembered as ahead of his time


Trump may roll back much of Obamas agenda, but he cant change that the president was right when he was wrong

It remains to be seen how much of President Barack Obama’s legacy will remain in place during and after President Donald Trump’s administration. That said, the question of whether Obama’s policies will withstand Trump’s orange vengeance is very different from the question of how they will be
judged by history.
When it comes to the latter, there are at least three issues in which Obama will likely be judged as analogous to Woodrow Wilson when he pushed for entry into the League of Nations or Dwight Eisenhower when he urged caution about the military-industrial complex — that is, as being far ahead of his time.
1. Fighting global warming
You would think that, if the overwhelming majority of the scientific community agreed that an apocalypse-level event was impending, humanity would rush to avert it. Unfortunately, both the president before Obama (George W. Bush) and the one after him (Donald Trump) have ignored the threat posed by man-made global warming. Obama, on the other hand, has taken unprecedented steps to try to curb global warming’s impact, most notably signing the Paris Agreement in December. In addition to a number of executive actions, Obama has made commendable efforts to curb the burning of fossil fuels both in this country and throughout the world. When future movies are made about our era, Obama will be remembered as the president who saw the impending calamity and took the first necessary steps toward averting it — and Trump will be remembered as the blundering fool who refused to heed the warning signs.
2. Providing health insurance to all Americans
Video10 Days That Define the Obama Presidency
There is no greater sign of economic privilege than acting like health insurance should not be guaranteed to all Americans — if you have taken that stance, you are too economically secure to empathize with those less fortunate than yourself and/or too comfortable in your ideological dogma to allow human suffering to influence your opinions. Nevertheless, harsh reality is going to intrude if Republicans repeal the Affordable Care Act without an adequate replacement, and 22 million Americans lose their insurance.

68 of workers do this and we wonder why we have security problems!

68 of workers do this and we wonder why we have security problems!


Ive always believed that information security is a people problem that goes deep into the psychology of how we think. Heres a great example...starting at 0:24:

http://johnmaxwellteam.com/industrious/

This is the basis for why our so-called leaders rise to power, why theres a gap between the haves and have-nots, and why so many "ailments" afflict society. Many people simply dont believe in themselves and have no desire or motivation to get any better.

Are you going to let this drive your information security program!?

Is this as good as youre going to get or are you going to get any better?

As Og Mandino said, Use wisely your power of choice

4 Reasons Why YOU Dont want to Touch Social Learning with a Barge Pole

4 Reasons Why YOU Dont want to Touch Social Learning with a Barge Pole


So, you recently read Jane Bozarths Social Learning for Trainers and followed it up with a read of Enterprise 2.0 by McAfee and The New Social Learning by Conner and Bingham. Youre excited by the promise of social software for learning. Youre already a Facebook and Twitter junkie and life couldnt be better with vendors announcing "Facebook for the enterprise". Wow! Youre going to be a hot-shot social learning pro, arent you? Errrm... think again. Life as a social learning consultant isnt a bed of roses and while the glamour of the Scobels, Hinchliffes, Ghoshes, Schrecks and others is inviting, youre likely to have a rough road ahead. Behind the glitz and glamour is a tough, painstaking albeit eventually fulfilling job, which you absolutely need to know about. So, before you get charmed into this shiny new world read my little disclaimer - it aint easy!

Its Not Really Facebook for the Enterprise
Ok, ok I know you love Facebook and I know Jane says you could potentially use established tools like Facebook and Twitter for learning. Jane is right, I must say and I personally believe that the most mature social business implementations need to have porous walls. With that said, I have to also note that were just not there yet! And frankly, theres perhaps a middle ground we need whichll just take some time. In the mean time, while you revel in the glory of Facebook, your employers need single sign on, integration with other systems, security, governance, uptime guarantees, content ownership assurances, and what not. Ah! That doesnt seem as cool anymore, does it? If youre heading the social learning route, remember that showing off the success of #lrnchat or the Learning and Skills Group is just the first step.

Youll be a Consultant with No Direct Control Ever heard of organisational politics? Its the bad phrase to describe the tension between innovation, internal systems and organisational structure. Once youve gone ahead and wowed YOUR boss with that demo of #lrnchat or or that matter your own PKM approach powered by social media, you should really have a free rein. Or should you? Well if youre championing the cause of collaborative learning in the enterprise, you cant do it alone. You need to get IT to buy into supporting you. Youll need to get leadership to champion your proposal, and to do that, youll need to champion some of their goals. As it turns out, none of them are your puppets - so getting the organisational machinery to start working in the same direction can mean several emails, presentations, meetings, arguments and consultative discussions. Forget about your role as an instructional designer - youre now only a consultant. You have no direct control. Hell, you cant even control behaviours for your learners. At least in the classroom you could set a few rules for participation. Now you need to model their exisiting collaborative behaviours onto your system. Youll often feel that "Click Next to Continue" in elearning or "Lets move to the next exercise." in the classroom gave you more power. Are you happy to live with that for some time?

Its Not the Kool-Aid Youve been Drinking
So, youre happy to rough it out - after all theres the pot of gold at the end of the rainbow! I guarantee you, there is one, but its far, far away. Before you can get to the wonderful effects that youve only read about it blogs, youll need to do heaps of hard work. As a start, you may need to create dozens of proofs of concepts for the scores of teams in your organisation. Its not just about getting the executives involved, people are at the center of social business. Be prepared to sit at your desk for hours uploading files, setting up wikis, creating discussion areas and helping people wrap their heads around emergent collaboration. Be prepared to get laughed at and to take the feedback, go back, work and come back more resilient. Even when your community starts to thrive, things wont just happen by magic. Theres a lot of unglamourous work involved in community management, Im afraid. Take a look at what Donald Taylor does for the Learning and Skills Group and what Tom, Dave and Jeanette do for the Articulate community. In fact, with all the content curation, one-on-one support, online facilitation and constant manual gardening that Dave Anderson does, I wonder when he sleeps. Its effective, its useful and it comes from a genuine desire to help people. It may end up being glitzy and glamourous, but dont count on it.

Youve Got To Build Comfort with "Good Enough"
As an elearning pro and even as a trainer, you would have fussed hours, days, weeks and months to get things just right. After all, that slide needs to look polished. That activity needs to be instructionally sound. That elusive goal of perfection keeps you going everyday. Social learning has its own levels of perfection, but that perfection doesnt come from the quality of content. A badly formatted, abrupt, but contextualised answer is good enough for a social QnA environment. Its not pretty, nor is it the most awesome content - its just effective and works. It takes great patience to keep looking at gigabytes of user generated content that may not be as good as what you could have created but is so contextualised, that its far more effective. In social business, perfection comes from being an integral part of the way we work. Perfection is when information flows seamlessly across the internet and the intranet, and people can consume byte-sized content when they want to, where they want to. Its perfection all right, but of a different kind.
If youve read this far, you probably see my point - being a social learning pro involves a lot of hard work. Its immensely fulfilling; after a while a lot more than just doing instructional design or training. Be prepared however, to take the long, hard road there. Put your heads down, think big, start small and keep iterating. And when you really start to deliver value, which could be sometime away, the accolades may come too. I guess its just a question of being patient. Thats just my two cents - what do you think?

A core reason why security challenges go unresolved

A core reason why security challenges go unresolved


Constantly dealing with information security issues in your organization? Its really about dealing with management, peers, and subordinates. Heres some motivation:

"The ability to deal with people is as purchasable a commodity as sugar of coffee, and I will pay more for that ability than for any other under the sun." -John D. Rockefeller

If youre in search of other ideas on how to get (and keep) people on board with security, here are some pieces Ive written on the subject.
