TechBytes 09: Fix your slow WiFi connection

WiFi is a wireless networking technology using 2.4GHz ultra high frequency and 5GHz super high frequency radio bands. This technology is excessively used by smart devices and computers. So when in a particular area a lot of WiFi signal is generated it creates a channel overlapping. WiFi has 13 usable channels in 2.4GHz frequency range with 3 of them operating as main channels. These are channel 1, 6 & 11. Channel overlapping is not a big problem with 5GHz WiFi routers due to having 165 channels, of them 25 operating as main channels. So for today, we are going to discuss how to solve this problem of channel overlapping.

WiFi 2.4Ghz Channels

Now the methodology will be to find a comparatively non-congested channel and set your WiFi router to use that channel. Let's find and analyze WiFi channels first.

Download following apps according to your operating system. Android - Windows

Now start the app and observe which channel is not that much congested.

Wifi Analyzer

Now let's see how to change the WiFi frequency channel settings on a WiFi router. I'm using a TP-Link WR841N router for demonstration purpose.

Open your web browser and go to http://192.168.0.1 or http://tplinkwifi.net/; type in your username and password. (Default- admin, admin)

Then navigate to the following section and select the un-congested channel you figured out from WiFi channel analyzer software.

WiFi Channel Settings

Click save and restart your router. Hope you'll have a more stable WiFi connection with low ping and interference with other WiFi access points now. Cheers!

TechBytes 03: Dueling Neural Networks

What does these pictures look like to you? Pictures of a person from 2014-2017, right? No. Actually these pictures are fake. A new technology called Dueling Neuron Network, an advancement in Artificial Intelligence helped creating this. Dueling neural network is a system where two neuron networks contesting with each other like in a digital cat and mouse game. It is used to generate audible and visual data. The neural network has produced many pictures like the above ones. They look like real but they aren’t. GAN (Generative Adversarial Network) created these fake pictures. This particular network system replicates real data to produce fake data. Between two pictures above, left one is generator network which has the task to create training data and to get as realistic as it can. On the other hand, the right one is discriminator network which has the task to identify which one is real and which one is fake. GAN is created through pairing these two ...
