Things that are killing your WI-FI signal

After a lot of backlash about choosing the default Windows browser, Microsoft has officially backed up and brought back a one-click browser change into Windows 11. For anyone who is not aware, when Windows 11 was released if you wanted to switch to another browser you had to go into the settings app and choose the default browser for different types of file extensions like HTML, HTM, PDF for opening on the web, etc. Of course, this was completely unnecessary and it was not well received by users. So after some time, Microsoft backpedaled to standard one click, choose your default browser solution that existed in the previous version of Windows OS. Altho sometimes Microsoft knows how to irritate its users base, it is good to know that they can also listen and fix things that are required.

Hello all the wonderful people and welcome to our new article where we take a little different turn than usual and discuss why keeping old electronics around the house is not such a good idea. We all have some drawer or in some bag around the house and in the end of the day if that electronic has battery inside it is probably not the smart thing to keep it.

So naturally, the question comes why it is a bad idea to have old electronics with batteries in them? Well unlike a battery failure with, say, some AA batteries jammed in the back of an old toy, the risk with a lithium-ion battery failing isn’t just some leaking and corrosion in the battery compartment, it’s a potential fire as the battery swells up and the gases (combined with the stored energy) turn the battery into a potential fire hazard.

Good thing is that the battery will not explode just like that, it will swallow over time and get bigger and bigger until the breaking point is reached and all the fire breaks lose. So if by any chance you have some old gadgets lying around you can check up on them and see if has swelling process started, if yes, dispose properly of that piece of the old device immediately.

How to keep old electronics

If you’re not ready to get rid of the gadget then it’s best to charge it properly for storage. Proper charging keeps the battery cells and circuits in optimum health.

While recommendations vary by manufacturer and application, the general consensus is that lithium-ion batteries should be charged to approximately 40%. (Some manufacturers recommend charging 50% or 60% instead.)

Really, the important part here isn’t the exact percentage. What’s important is ensuring that the battery is charged to roughly half capacity and not stored with a completely discharged or completely full battery.

Discharge rates on lithium-ion batteries in completely powered-off devices are very slow, but you should still plan to top off the charge every 12-18 months or so to keep it around 50%.

If you wanted to go above and beyond, a metal storage container with a snug lid on a basement shelf with a desiccant pack inside to control the moisture would offer optimum conditions.

Qtcore4.dll Error - What is it?

Qtcore4.dll is a dynamic link library file that helps Microsoft Windows in loading several key components of the system.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers. So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard. The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.

A couple of Windows 10 users have reported an error on domain-connected systems when they tried accessing their computer systems remotely. This occurs when the network level authentication or NLA is enabled on the computer. If you are one of these users, you better keep reading as this post will guide you on how you can fix this error. To resolve this issue, there are several workarounds you can try. You can either disable this option directly via properties or you can also modify some registry entries or sub-keys and restart the system. When you encounter this problem, an error message pops up that states:

“The remote computer that you are trying to connect to requires network level authentication (NLA), but your windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.”

Or you could also see this error message instead:

“The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support.”

Before you proceed in troubleshooting the problem using the options provided below, you need to create a backup for your data or system restore point as well as make a copy of any registry entries you are going to modify.

Option 1 – Disable Network Level Authentication via Properties

The NLA is a useful tool that provides your computer with extra security and helps network administrators in controlling who can log into the system with just a click of a single box. However, there are times when it can become a disadvantage and could prevent you from accessing your system remotely. Thus, you need to disable it using Properties.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” and tap Enter to open System Properties.
• Next, go to the remote tab and uncheck the checkbox for the “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)” option.
• Now click the Apply button to save the changes made and exit System Properties and then try logging into the remote computer again and see if the problem is fixed or not.

Option 2 – Disable NLA via Registry Editor

Note that you can only use this option if the first one didn’t work for you. Take note that this option will require you to restart your PC completely which could mean some downtime if your computer is running a production server. So make sure to save all your work.

• Tap the Win + R keys to open the Run dialog box and then type in “Regedit” in the field and tap Enter to open the Registry Editor.
• From there, click on File > Connect Network Registry and input the details of the remote computer and then try to connect.
• Navigate to the path below after you’re connected:

HKLM >SYSTEM > CurrentControlSet > Control >Terminal Server > WinStations > RDP-Tcp

• After that, change the values given below to “0”
  • SecurityLayer
  • UserAuthentication
• The navigate to PowerShell and execute this command – restart-computer

Option 3 – Disable NLA via PowerShell

PowerShell allows you to tap into the remote computer and once you’ve targeted the machine, you can execute the commands given below to disable NLA.

• Tap the Win + S to open Search and then type in “PowerShell” in the field. Right-click on the related result and select the “Run as administrator” option.
• After opening PowerShell, execute the command below:

2. Once in the PowerShell, execute the following command:

$TargetMachine = “Target-Machine-Name” (Get-WmiObject -class “Win32_TSGeneralSetting” -Namespace rootcimv2terminalservices -ComputerName $TargetMachine -Filter “TerminalName=’RDP-tcp'”).SetUserAuthenticationRequired(0) Note: In the command given, the “Target-Machine-Name” is the name of the machine you are targeting.

Option 4 – Use the Group Policy Editor to disable NLA

Another option you can use to disable NLA is via the Group Policy Editor. This is ideal for you if you are blanket disabling. Just take note that the Group Policy Editor is a powerful tool and that if you make some mistakes by changing values you have no clue about, you can render your computer useless so make sure that you create a backup for all the values before you proceed.

• Tap the Win + R keys to open the Run dialog box.
• Then type in “gpedit.msc” and tap Enter to open the Group Policy Editor.
• From there, go to this path – Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security
• After that, search for “Require user authentication for remote connections by using Network Level Authentication” and set it to disabled.
• Now check if the error is fixed or not.

Mozilla Firefox has introduced a new feature known as Restart with Windows which allows the browser to automatically start when your Windows 10 computer boots. This means that if you leave the Firefox browser opened while shutting down your computer, Firefox will re-open automatically along with the tabs that were opened right before you shut down your computer. Although some users may find this feature convenient, there are others who do not approve at all as it could be a nuisance. So if you’re one of the latter, then read on as this post will show you how you can disable the Restart with Windows feature in the Firefox browser on your Windows 10 computer. Refer to the instructions laid out below to get started.

• Step 1: Open Mozilla Firefox and if it’s opened already, just open a new tab and then type the following text in the address bar:

about:config

• Step 2: After typing the text given above, hit Enter and if a prompt with a warning message pops up, simply click on the “I accept the risk!” button to proceed.
• Step 3: Next, type “Restart” in the search filter which should display the following preference in the window:

“toolkit.winRegisterApplicationRestart”

• Step 4: After that, check for the preference value and then see if it’s set to true or not. If it is set to true, then it means that the Restart with Windows feature is enabled so obviously, to disable it, you need to set its value to false.
• Step 5: Now restart your computer without closing Firefox. After restarting your computer, you should no longer see Firefox starting automatically.

The Restart with Windows feature by default is disabled for most users. On the other hand, Mozilla will have this feature enabled as the default configuration in the coming weeks so it’s best that you now know what to do when that time comes since the newer versions of Mozilla Firefox are already being shipped with the Restart with Windows feature. However, if this post did not help you, then you might want to check if the feature has been added to the Startup folder, and from there, you can disable this startup program using the Task Manager > Startup tab.
