Windows 10: MediaTek MT7902 not working

Recently had an update on my Acer Aspire 3 laptop and the wireless LAN card decided to stop working MediaTek Wi-Fi MT7902 so now I have no wireless internet connection on my laptop and I’m unable to fix it

:)

 

Publisher MediaTek Blocked?


Using the tutorial Unblock File in Windows 10 didn't work.

Simrick suggested http://www.technicalnotes.org/fix-th...in-windows-10/

From this suggestion I found a workaround of running the driver setup from CMD, which worked, but I'm still left with a blocked file. See certificate details below ...





Any ideas how to fix this?

 

Publisher MediaTek Blocked?

Sorry, I'm not very good with certificates, but it looks to me like MediaTek let their certificate expire? Nope, just saw the 2017 date....it's been revoked, not sure why.

Maybe you could contact them, and point them to this thread, and ask them why it's been revoked and how to resolve this? Seems to me they have to sort it out with Verisign and Symantec, nothing you can do.

Contact Locations - MediaTek

Honestly, I don't think I'd even want to try and figure out how to bypass a revoked certificate on my system....(although we just did it basically for you - to get the thing installed...)

 

What is the difference between snapdragon and mediaTek?

Hi Ahsan Mehmood1,



Welcome to Microsoft Community.

Snapdragon vs. MediaTek:

Snapdragon and MediaTek are two prominent semiconductor companies that manufacture mobile processors for smartphones and other devices. Here's a simplified comparison of the core differences between the two:

Company Background:

• Snapdragon: Developed by Qualcomm, a well-established American semiconductor company with a strong presence in the mobile industry.
  
• MediaTek: A Taiwanese semiconductor company known for providing cost-effective solutions for smartphones.
  

Level of Patents:

• Snapdragon: Qualcomm holds a significant number of patents related to mobile technologies, making it a leader in terms of intellectual property.
  
• MediaTek: MediaTek has fewer patents compared to Qualcomm but still holds several key patents.
  

Integration:

• Snapdragon: Qualcomm's Snapdragon processors often offer better integration of various components like modem, graphics, and AI capabilities, resulting in power efficiency and performance.
  

• MediaTek: MediaTek processors tend to offer a more cost-effective solution with slightly less integration, which can affect power efficiency.
  

Instruction Sets:

• Snapdragon: Uses ARM's instruction set architecture (ISA) like Cortex-A and Adreno for graphics.
  

• MediaTek: Also uses ARM's ISA for CPU cores and Mali for graphics in many of their processors.
  

Architectural Licenses:

• Snapdragon: Qualcomm has the capability to customize and license ARM architectures, giving them more flexibility in design.
  
• MediaTek: MediaTek primarily licenses ARM's standard architectures without extensive customizations.
  

Market Share:

• Snapdragon: Qualcomm Snapdragon processors are widely used in premium and mid-range smartphones, giving them a significant market share, particularly in high-end devices.
  

• MediaTek: MediaTek processors are often found in mid-range and budget smartphones, where they have a substantial market share.
  

Applicable Scenarios:

• Snapdragon processors are a preferred choice for premium smartphones and flagship devices due to their higher performance, better power efficiency, and extensive integration of advanced technologies. They are also popular in devices requiring cutting-edge features like 5G connectivity and AI capabilities.
  
• MediaTek processors are commonly used in mid-range and budget smartphones, where cost-effectiveness is a priority. MediaTek's offerings provide decent performance for everyday tasks and are suitable for smartphones in the affordable price range. They are also found in various other consumer electronics like smart TVs, tablets, and IoT devices.
  

In summary, the choice between Snapdragon and MediaTek processors depends on the specific requirements of the device and its target market. Qualcomm's Snapdragon processors are generally favored for high-end devices, while MediaTek's processors are popular for cost-effective solutions. Both companies have their strengths and cater to different segments of the market.
