Can’t connect to this network Internet connectivity issues present a complex problem with simple solutions for PC and laptop users. First, it is usually recommended that users rule out problems with the internet connection, router, and Wi-Fi settings before proceeding to troubleshoot settings on your PC/laptop. Once the rest are ruled out, we can then proceed with the following troubleshooting steps and guidelines to fix your wifi connection issue: The first step is to update your windows network adapter driver. Connectivity problems may arise if your network driver is not updated or if it is incompatible with the network adapter. To do so, you may resort to any third-party driver scanning and installing programs found online. This solution should have resorted if users don’t want the hassle of perusing through windows settings that users may not be familiar with. However, this solution requires a pre-existing internet connection other than wifi, so it is recommended you have a backup internet connection via ethernet.

The second step is to uninstall the driver for your network adapter. This solution is to be reported if there is an issue with the driver as restarting the PC after the following steps let windows reinstall the driver again:

• Open the quick access menu on your keyboard by pressing the Windows key and X key at the same time and select “Device Manager” from the menu list.
• From the list of devices, select “Network Adapters”
• Usually on the top of the list is the Wireless Network Adapter
• Right-click the Wireless Network Adapter and select the option to “Uninstall device”
• You will be given a confirmation in a new separate window to proceed. Click “Uninstall” to proceed.
• After completing the previous steps, try rebooting your Windows PC and reconnecting to see if it works.

A third step is to disable the 802.1 1n modes of your network adapter by following the next steps:

• First press the Windows logo key and the X key at the same time to bring up the quick-access menu. And like the previous step, select “Device Manager”
• From the list of devices, select “Network Adapters”
• Right-click the Wireless Network Adapter from the drop-down menu and select properties
• Under properties, select the “Advanced” tab then select the 802.1 1n Mode. To the right drop-down menu change the option to  “Disabled” and click “Ok”
• After, try to re-establish the connection to see if the steps have worked.

In the event that any of the preceding did not fix your problem, it helps to take a second look at the router and network settings using the interface provided by your ISP. A simple reset to the back of your router often fixes the issue. Also, try to check if you have any other administrative capabilities over the network to determine whether your device, in particular, has been MAC filtered or if the frequency of your wireless adapter is not compatible with the broadcast frequency of your router.

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature:  POPELER SYSTEM, S.L. Entry Point:   0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

 Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation.

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
