D-Link Covr 2202 Mesh WIFI initial Review

How often does your device lose connection to the internet when you enter a spot in your home despite you having bought and setup a powerful WIFI router somewhere in the middle?

It’s frustrating, right?

Now, that’s just the reality of WIFI technology as radio signals do have a hard time penetrating walls or other objects. It’s just physics.

And this is a problem that mesh network technology is here to solve. Mesh network technology is basically the use of multiple connected network devices to provide consistent WIFI coverage for a large area and eliminate blindspots. And when the connected device move from one area of the house to the next, the mesh network knows how to pass the connection to the router that provide the best connection.

In this review, we will be looking at D-Link’s latest WIFI mesh network product for home users, the Covr-2202.

The Covr-2202 is a tri-band WIFI mesh networking product that uses two units to cover 550 sqm of space with WIFI signal. Unlike the dual-band implementation found in other WIFI mesh solution, the Covr-2202 uses a third 5Ghz WIFI band for communication and data exchange between the two units. This frees up the 2.4Ghz and 5Ghz bands for devices to use to connect to the network. This means the connected devices can still stream 4K content, handle large downloads and browse the web without any drop in performance.

The marketing material and the specifications made it to be the WIFI solution to go for. But those weren’t the reasons that I got it.

For me, I got the device because it was an alternative purchase. Initially, I was looking for the Asus Blue Cave WIFI router to replace my previous Asus RT-AC68U WIFI router. I wanted something nicely designed that will complement my new desk, perform well and take up less space. The three antennas of the RT-AC68U were just ugly.

And if Apple didn’t discontinue their networking products and make new ones, I would have gone with their AirPort-series of networking devices.

Sadly, according to the salesperson, Asus Blue Cave was discontinued. He suggested that I go for Covr-2202 because it costs about the same, won awards and performs better. During the conversation, I asked about the Covr-1203 because it looked interesting and fulfilled my requirement for a small router. It turns out the performance wasn’t as good and was an older generation, which kind of defeat the purpose of buying a new WIFI router.

Before I made the purchase, I asked to see the physical product. Lucky for me, there was a display set on hand and the salesperson showed me what it looked like. I find myself liking it and made the decision to buy.

Unboxing

This is the box after removing the plastic. I got to admit it definitely look enticing and cool when compared to other networking products sold by other companies. Most networking companies don’t really bother with making nice packages.

Once you open it, you are greeted to the following sight.

Now that definitely remind me of the packagings used by certain brand of cosmetic products. And after you remove the cover, the two Covr-2202 units greet you. They are welcoming you to take them out of the box.

The white overall and the bronze-like band at the bottom definitely complement my desk that features light wood colour with white metal struts.

And the small size definitely help freed up more space on my desk that I can use for other purpose. Overall, my desk just look less cluttered.

Installation and set up

Router installation and setup is really easy and simple.

Within the box, D-link provided a small card containing instruction on where to download the their official WIFI mobile app. When you launched the app, it comes with instructions that you can follow step-by-step to install and power on the device.

At a specific stage of the setup process, the app will ask for the network name and passwords. You can do it manually or scan the QR code located on the small card. However, it is advisable to set a different network name and password after the setup process is completed.

Although I encountered some issue during the setup process due to my lack of understanding how mesh networking works, I was able to recover from the mistakes and redo the whole setup again within minutes. This is definitely helpful for those who are mostly clueless about networking and simply needed their WIFI up and running in no time.

Performance

My home subscribes to 1Gbps fibre broadband. Therefore, it’s important that we can maximise our use of the bandwidth if not it would be a waste of money. Compared to the old Asus router, the WIFI performance of this new router is so much better. On WIFI alone, I’m able to achieve download speeds that’s more than 500mbps and upload speed of slightly more than 300mbps. And that’s taking into account the overall residential broadband bandwidth tend to be lower since many people are home and using the internet.

With speeds at 500mbps, I can watch YouTube video or Netflix with relative ease and no lag. And I do have at least 5 other devices connected to the same mesh network. So the performance is definitely there.

So for the price I paid, I would say it’s worth it.

Working on new things

It’s been nearly a month since there’s any new content posted and I feel obligated to provide an update of sort.

I have recently got myself into a new habit of waking up at 5.15am in the morning to go for a 30 minutes run around my neighbourhood. It has been going on for the past three weeks now and there are multiple reasons. One, I promised myself that I need to be healthy and reduce my stress level. And since I do enjoy running, it’s the best kind of exercise for me. Second, my working hours, especially that of the evening, is unpredictable given my recent change to a new project. And usually by then, I will be too exhausted to exercise. So, a morning run is the best.

I have also signed up for a short Udemy course on Creative Writing and is currently undergoing the lessons.

Next, I also decided to do commercial writing. And no, no money involved just yet. What I meant is that I write for companies, using my technical skills and experience. It’s also a good place for me to start if I need to do writing as a career.

Finally, I’m still working on my novel; still trying to work out the kinks of the first chapter. And I’ll be honest. I’m having a writers block of sort because I recently find myself not feeling passionate about this particular storyline set in the Intertwined Fate universe. Initially I started the project because I felt like I need to do a slightly bigger fiction project before I go to the next level. I’ve tried writing space opera a few years ago and my skills then didn’t allow me to do a good job. That’s why I would be stupid for me to attempt it again.

The sci-fi LGBT-themed short story I wrote previously for the Intertwined Fate universe was a good starting point. You can read the first chapter here. That story was small enough and manageable for me. Furthermore, I felt the passion for it and enjoyed writing it. Now, it’s just really hard for me to find that passion back.

Image Downsizer

Let’s say you have images that you wish to load into your application. However, instead of having the user downscale or downsize those images first, your application could do it for them.

Below is a piece of code I wrote in C# that will do just that by brute forcing. Admittedly, it’s not the best solution. An AI probably could do it better but in many cases, the following works pretty well.

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;

namespace ImageTuner
{
    class Program
    {
        static void Main(string[] args)
        {
            string originalImageFile = "<image image file&gt;.jpg";
            string scaledImageFile = "<downsized image file&gt;.jpg";
            bool imageMatchCriterion = false;
            bool imageStillTooBig = false;

            float resolutionScaleFactor = 0.95f;
            long jpegQualityLevel = 100L;

            using (var originalImage = new Bitmap(originalImageFile))
            {
                while (!imageMatchCriterion)
                {
                    Console.WriteLine("Image doesn't match size criterion. Resizing.");
                    int scaledHeight = (int)(originalImage.Height * resolutionScaleFactor);
                    int scaledWidth = (int)(originalImage.Width * resolutionScaleFactor);

                    using (var toCompress = new Bitmap(originalImage, new Size(height: scaledHeight, width: scaledWidth)))
                    {
                        var jpgEncoder = GetEncoder(ImageFormat.Jpeg);
                        var myEncoder = Encoder.Quality;
                        var myEncoderParameters = new EncoderParameters(1);

                        var myEncoderParameter = new EncoderParameter(myEncoder, jpegQualityLevel);
                        myEncoderParameters.Param[0] = myEncoderParameter;

                        using (var tempStream = new MemoryStream())
                        {
                            //Save the image byte to memory first.
                            toCompress.Save(tempStream, jpgEncoder, myEncoderParameters);
                            byte[] imageSize = tempStream.ToArray();
                            //Check the image size in memory. If it's too big, continue to loop.
                            if (imageSize.Length <= 512000)
                            {
                                imageMatchCriterion = true;
                                using (var saveStream = new FileStream(scaledImageFile, FileMode.Create))
                                {
                                    toCompress.Save(saveStream, jpgEncoder, myEncoderParameters);
                                }
                            }

                                    //Reduce the resolution of the image by 10 percent each time.
                                    resolutionScaleFactor -= 0.10f;
                                }
                                else
                                {
                                    //When the resolution scaling already reach 60%, time to look at reducing the quality level by 5 each time.
                                    if (jpegQualityLevel &gt; 50)
                                    {

                                        break;

Writing longhand with pen and paper

How many of you write your content using pen and paper before actually getting it onto other platforms for publishing?

If you do write using pen and paper, it’s great and would love to hear your thoughts about it.

For most of us, we’d probably write on computers. I write predominantly on computers too. It’s just a much more powerful tool, more convenient, and probably could write much faster.

However, due to the nature of my work, technology burnout is inevitable. For several days during this week, I couldn’t bring myself to use a computer or even my phone to write anything. Yet, there’s a book that need writing.

This was how the decision to reintroduce pen and paper into my writing life came about. I got a lecture pad and a black ballpoint pen. Then I got down to writing.

The experience was definitely painful at first because it’s been a while since I wrote longhand using pen and paper. After finding my handwriting in a total mess and my hand aching badly, I decided to use the pen correctly and even went to google for the right way to hold the pen or pencil for that matter. Then it was time to put it into practice.

I would say there were definitely some good and bad that came out of this process.

For me, it has been therapeutic. The chance to get away from technology is just great for my mental health.

Further more, I could focus better on my writing because there’s no internet involved. No Netflix. No music. No internet browser. If you put your technological devices out of reach, you have no choice but focus on the act of writing and the story you want to tell.

The second advantage come in the form of deliberate writing. Because writing on paper meant it’s nearly impossible to change what you wrote. Unless you want to leave behind lines after lines of strikethroughs or whiteouts, every word you want to put down on paper have to be the right word. This slows down your writing and forces you to think. This has the added advantage of allowing you to identify if there’s loopholes or problems with your content. This is especially helpful for me as a pantser because I won’t run astray with my writing and create plot holes.

The third advantage was that it’s just more natural. You can do whatever you want. Scribble along the margin of the page. Skip lines. Doodle. The freedom meant you could explore your ideas and thoughts in a more natural and faster way rather than having to conform to what the computer and software forces you to do.

The fourth advantage is the permanence of the content. Unless your notebook or lecture pad end up getting soak, caught fire or the pieces of paper blown away by the wind, you can always trust that your content won’t go away. That’s unlike when you are using a computer to write. Machine can fail. Storage devices, including cloud storage, can fail or corrupt your data.

But not everything is all so shiny and great.

The biggest disadvantage with using pen and paper is the speed of writing. Your arms and hands don’t move as fast when you have to draw out the arches and lines associated with latin characters whereas with a computer, a key press means a letter. Because of that, I find it much harder to get into the flow.

The second disadvantage is you can’t edit the content like you could on the computer. Every word that you write on paper is permanently set in stone, so to speak. If you want to change something, you have to strike out what you wrote or use whiteouts. And if you are like me who makes quite a lot of mistakes when writing, you will find that your paper may end up becoming a complete mess and hard to comprehend.

As for portability, it doesn’t concern me. I always bring a backpack when I go to work and I could just shove the lecture pad in it. And when it comes to publishing, well, since I’m writing a novel, it would be much later in the writing process that I have to type them all out. With that, I’d probably do my editing concurrently. So I get to kill two birds with one stone.

Now, I won’t say every writer should write longhand using pen and paper. For most people, it would be very tedious and tiring. So if you prefer to write using your computer, then by all means do that. At the end of the day, the most important thing is getting your content out for your audience to consume and encourage them to come back for more. But if you find that your computer is getting in the way of you doing your work, then maybe it’s time to go old-school.

Dealing with burnout

I don’t want to treat this blog as my personal diary. I needed it to be the place where readers will only find useful and good content.

But I feel compelled to share with the world my current situation.

Two weeks ago, I worked a 60 hour-week instead of the usual 44 hour and I went four days surviving only on 6 hours of sleep total, relying on caffeine so that I could code and fix bugs.

And last week, it was a 50 hour-week and I didn’t pay off my sleep debt.

And the kicker was, the company doesn’t give time-off to us for burning our weekends and nights just because they deemed our jobs to be “professional” and doesn’t care how we deliver the results.

I was thinking maybe I should throw in some more physical activities to help contribute to my energy levels and reduce my stress levels. It helped a little.

Then my boss told me I have to quickly take over the product development because the main developer for it was leaving by the end of the month while my current project has multiple deliverables also by the end of the month.

So I suspect this coming week will be another 60 hour-week, possibly even 70 hour-week, depending on how things turn out. I also have a medical appointment for some conditions that I’m suffering from and needed some relief.

With all that, I thought I could write my novel during whatever free time I have. I’m pushing hard to write my novel because I intend to get it out before my next birthday in a few months time. The novel will be at least 70,000 words long, meaning I need to be churning out 23,000 words each month.

And for the month of June, I only managed 10,000 words instead of 23,000 with the month coming to an end. Most of the time, I had to deal with wasted hours of staring at the blank canvas, not sure what to write. Words don’t come out. Even if they did, they felt forced. They lack life.

In addition to that, I have had literal nightmares for several days, continue to suffer from insufficient sleep due to anxiety. The hatred for my day job continues to grow. Even my attempts to see it “working in service of my writing” didn’t do me much good. Mind you, I am already at this stage where I am no longer interested in building software. I really just want to do something else for a living and is just forcing myself to go to work so that I can pay off my credit card debt, my bills and generally live a decent life in this expensive country.

Right now, I’m frustrated and disillusioned. My gastric issue and body pain came back, requiring me to survive on antacid, painkillers and muscle relaxant. And as a writer, I don’t even have the time to read so that I can be inspired and learn new stuff…

I just don’t know how long I can keep this up.
