Windows 10: Slooooow wifi connection on surface 3 pro

Suddenly I am experiencing very slow wifi speeds on my surface 3 pro. On all my other devices (desktop and iPhone) I get around 150 Mbs. Now on the Surface, I am getting under 30 Mbs. Recently I have added Version 1909 build:18363.476. I have removed the Marvell Wifi driver and reinstalled it with no change in speed.
All the searches on the web turn up old information. I would appreciate any input and information to help me with this problem.

Thanks
John

Surface Pro 3

Hi ChrisWaters3,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. Does the battery drain out, if the tablet is not connected to peripherals?
   
   
2. Which version of Windows you are using? (To check, type: winver in start menu and hit enter.)
   

I understand how something like this can try your patience. This issue is an indication of faulty drivers or incompatible driver.
However, I suggest you to follow the troubleshooting steps mentioned below:

Method 1: Check the drivers.

Step1: Battery driver

1. Press Windows andR
   key together on your Keyboard.
2. Type devmgmt.msc and hit enter.
   
3. Click on view on top > Select Show hidden devices.
   
4. Expand the Batteries option from the list.
   
5. Select the ACPI Compliant Control Method Battery> right click on the driver and click on
   Properties.
6. Click on Driver tab > check if you have the option to
   Roll Back Driver.
7. If yes, Roll back the driver or uninstall it and restart the computer.
   

Uninstalling the driver will be automatically installed after the system is restarted. Check if the issue is fixed.

Step 2: Keyboard driver.

1. In the Device manager, go to ‘Other devices’, you will find
   Unknown devices.
   
2. Double tap on the unknown device > click on
   Driver tab> click on update driver.
   
3. Select browse my computer for driver software> Click on Let me pick from a list of device drivers
   
4. Select keyboard, then click ‘Next’.
   
5. Select HID Keyboard device and click finish.
   

Method 2: Run the toolkit.


Note: If your Surface is managed by your work or school, check with your organization's IT department before running the tool.

I would suggest you to run the toolkit provided by Microsoft on
Fix common Surface
problems using the Surface Diagnostic Toolkit

If the above steps, doesn’t fix the issue. I would suggest you to follow the steps mentioned in the article on
Surface Pro 3 Battery
FAQ for the Surface Pro Embedded Controller Firmware update.


Hope it helps.

Accessing wifi on Surface Pro 3

Hi Mikel,

There are several reasons which may cause the Surface Pro 3 not to connect to the WiFi. In order for us to effectively assist you with your concern, we just have a few questions for you:

• Were there any changes made to your computer prior to the issue?
• Have you tried running the network troubleshooter?
• Have you tried updating the network adapter driver?
• have you tried rolling back the network adapter driver?

Regards.

 

Surface 3 connection to WiFi network

I am attempting to sign into a known wifi network that requires a user name and password (which I have). My name and password work on all my devices BUT the surface 3. Once I input the username and password, the screen boots me to the bottom of the list
and asks for the name and password 3+ times before it tells me I cannot connect to the network. Any thoughts or recommendations on how to get into this network? The Surface 3 works beautifully at my home on my home wifi, which is only password encrypted

Thank you
