In today's time, Wi-Fi is a common occurrence, each household has it, on town squares, there are free Wi-Fi hotspots, etc. But sometimes when relaxing at home WI-Fi can fail on us and stop working. If this happens to you do not lose your mind because we have several troubleshooting help tips and ways to get it back quickly so you can continue with your browsing and using your internet.

Restart the Router and Computer

Yes, we will start with this typical cliche in IT and tech in general. Surprisingly this method still proves over and over again to be true and effective. Over time some electric components simply start working a little bit differently, electrostatic electricity can accumulate on some parts and they can cause issues. By turning off the device and leaving it for some time you are discharging accumulated electrostatics and placing it again into normal working mode.

Unplug your router and leave it for at least 30s like that, a full 1 min is recommended, and then plug it back. Turn it on and restart your computer in order to reboot addresses.

Reset DHCP

If simple have you tried unplugging it and plugging it back in did not work let us reset DHCP. Click on the start button and type in PowerShell, then click on Run as administrator. Once inside the PowerShell type in the following command followed by ENTER: ipconfig /release and after the command finishes, type in: ipconfig /renew also followed by ENTER key. Try the connection again.

Reset TCP/IP stack

The next thing that we will try if the previous one failed is to reset the TCP/IP stack to eliminate corruption of settings files. Like in the previous step, press Start and type in PowerShell and click on run as administrator. inside type in: netsh int IP reset and press ENTER key. Wait for the process to finish and reboot your PC.

Reset WinSock

WinSock is yet another part of Windows OS that is responsible for network communication and resetting it could solve the issue. Again go to PowerShell as described in previous steps and type in this time: winsock reset and press ENTER. Wait for the process to finish and restart your computer.

Other things you can try

Change TCP IP setting back to automatic if you have set manual Ip address on your computer.

Update your network driver via the manufacturer's website of your network adapter. There is a chance that somewhat updates are available to address some issues discovered.

Factory reset your router on the back by locating the reset button on it and pressing and holding it for around 10s.

Turn off your firewall and antivirus protection in order to eliminate it from blocking your internet access.

There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:

• Your PC’s motherboard should support both Legacy and UEFI.
• Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.

Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

• When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
• Make sure to run Command Prompt as admin and then execute this command: exe /convert
• After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
• As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
• Now save the changes made and exit as your computer will restart.

Windows 11 has come a long way from its infant stage. Today it is incredibly good and stable operating system that also looks good and modern. Unfortunately, fancy animations and good graphics come with a price, in this case, slower performance on some little older and weaker computers.

Animations itself which include also fading effects can sometimes feel slugging and laggy and have a general overall feeling of delay. For a more old-school instant experience, you can turn off animations.

In order to turn animations inside Windows 11 follow this simple guide:

First thing is to open Settings by pressing Windows + i key combination or you could open Start and in the search box type in Settings and then click on its icon.

Once inside settings on the left side find Accessibility and click on it to select it. Once it is selected on the right side choose Visual effects. Inside the visual effects section click on the switch next to Animation effects to OFF. You can also turn off transparency effects in this section if you wish if you have an older GPU in order to speed it up a little.

That is all you need to do, settings will be automatically saved and all animations will be turned off for a quicker and more responsive feeling when working inside W11

Today we will be solving the Device not found 3F0 error which is a common error, especially among HP (HP Pavilion G6), Lenovo, Acer, and Dell laptops/desktops. This error occurs when the computer is turned ON and when the system is about to boot. It can happen on windows 7,  8, or 10. When a mentioned error occurs one of the following messages will be displayed on your screen:

• “No bootable device – insert boot disk and press any key”
• “No Boot Device Found. Press any key to reboot the machine”
• “Boot Device Not Found. Please install an operating system on your hard disk. Hard Disk (3FO)”
• “No boot device is available”

The most common reasons for 3F0 error to occur is:

• Using the unbootable device or disk to boot from.
• If the bootable hard drive you are using might have corrupted or damaged somehow.
• MBR or boot sector is damaged on the bootable hard drive.
• If your system has gone through a virus or malware attack.
• The wrong boot order in the BIOS.
• Hard disk connection problem.
• System files or boot files unknowingly damaged.
• Corrupt hard drive partitions.

This is well, the most simple solution and the easiest one, try to change the boot sequence in the BIOS settings of your motherboard. Sometimes most easier solutions can provide great results and solve our problems. If sadly this fails and the issue persists move to the next solution.
