A picture of Xiaomi WiFi router

About a year ago I was in a tricky situation. I had just moved to a new flat that had a modern fiber-optic connection meaning that instead of connecting my router to a phone socket, there was an ethernet port on the wall. This meant, of course, that I had to go shopping for a new router after I was told by my internet provider that they don’t sell such routers, because “you can connect your computer to the ethernet port directly”…  🤦‍♂️ Like I would only have one device I wanted to connect to the internet. 🤣 (more…)

Load testing a Django based application with jMeter is a tricky thing to do since Django requires a CSRF (Cross-Site Request Forgery) token to be present on every POST request (unless you have disabled it, of course).  This tutorial helps you to hit the ground running with your Django tests, as I have prepared a ready made test file for you. 🤓 (more…)

Ethernet cables of different colors

📡 Wi-Fi or cable seems to be connected properly, but you just can't get online. Or maybe Windows even recognizes the issue and shows an exclamation mark ⚠️ close to the Wi-Fi icon but troubleshooting doesn’t do the trick. The first time I ran into this issue was a decade ago on Windows XP. Lately I have experienced the same problem multiple times on Windows 10. And I am not the only one. Even my dad called me the other day with the same issue. Luckily, the solution is simple. 😊

Manual solution

1) Press Win+R buttons simultaneously on your keyboard. This will open Windows' run dialog.

2) Type cmd and hit enter. This will show you a terminal window. Don't be scared of the black window, though.

3) In the terminal type ipconfig /release and hit enter. This will release IP addresses on all network interfaces. Some of them might fail, but don't be alarmed.

4) Now, write ipconfig /renew and hit enter. This will renew your local IP. Once the command is finished, you'll be connected to the internet.

Automatic solution

Sometimes, when this problem starts to occur, you might run into it every time you boot your computer. That's why I made a nice automatic script to solve the problem that you can download and place on your desktop. Double-clicking on it will do automatically the very same procedure described above. The only thing you have to do is to sit back and enjoy the show. 😎

 

Hopefully this fixed your network issues. ☺️
