Windows 10: Help Please! I have no idea what's going on with my Wi-Fi, or computer not being able to...

I had to repost this, since the last one wasn't getting enough traction. Please help! I genuinely want to know why this is happening. Clarification:The internet that I have is being used by many people so it was my first speculation that this was the issue, but having all devices that used my Wi-Fi other than my laptop turned off completely, the same situation occurred: Slow and poor internet speed/ connection on the windows computer, and the opposite on my apple laptop. For specifics, both devices are on the same floor as the gateway router, and approximately 24 ft away from it, so I am q

Flakey WI-FI - No Idea Why

@Samuria
From MS store I'm using wi-fi Explore. But any more info like channel # used or other networks is only available in Pro (paid for) edition:
This is scan of my devices:




I guess I'm missing a trick here - but as I mentioned I'm fairly computer illiterate.

Flakey WI-FI - No Idea Why

Hello,
I'm with a UK broadband ISP called TalkTalk - not through choice, but if you want FTTC, they were the only provider in town...literally.
We also have an Amazon Firestick (wi-fi) which we cannot use due to insufficient signal - our Samsung SMART TV is cat5e cabled. But, we also have YouTube issues when using the TV built-in apps.
We also have Spotify - which regularly loses Wi-fi connection during songs played via Sonos speakers. Same goes for our Asus laptop on wi-fi. All these items are on the ground floor of our small cottage.
Our main PC's are upstairs next to the router (Sagemcom Fast 5364), aslo (laughingly I guess) called the TalkTalk Wi-Fi Hub due to its superior wi-fi performance.
For years we had no problems at all - then just after we were 'upgraded' to this hub (and the Winter storms arrived in Autumn). Since then it seems to have been a steady downhill slide. Previously we had several Huawai routers e.g. HG633 & HG635 routers - no sign of a problem (apart from the Manufacturer being Chinese).

Before I engage with TalkTalk I would like to confirm my pc is working OK. File Explorer is suggesting to me ( I am largely computer illiterate) that all is not well. I'll attach a few screen captures by way of explanation:

I also tried to Map a Network drive to my Synology NAS & got this:



I was following an instruction in an old thread (from NavyLCDR - and he knows his stuff) - when I got the error & even I could guess all was not well in the Network!
So, before attempting to tackle TalkTalk (always a blood-pressure risk) I'd like to confirm my PC/network/router setup is at least fairly normal. But of course I need the help of Ten Forums!! as I am metaphorically & literally lost as far as computers are concerned.

Best,
Mike

 

Data cannot go through cellular when Wi-Fi connected.

Hi,

Thank you for writing to Microsoft Community Forums.

Could you please confirm if you are receiving any error message when you visit IPv6 sites when you are connected to your Wi-Fi?

I would suggest you to check if the IPv6 is enabled for Wi-Fi in your system. Please follow the steps below:

1. With your system being connected to Wi-Fi, click on the ‘Windows’ icon at the bottom left corner of your screen and type ‘Control Panel’. Open the control panel.
   
2. Click on ‘Network and Internet’.
   
3. Click on ‘Network and Sharing Centre’, you will be able to find ‘Change adapter settings’ on the left part of that Window.
   
4. Under ‘Change adapter settings’, double click on your Wi-Fi network, click on ‘Properties’.
   
5. You will be able to see ‘This connection uses the following items’, scroll down to find the ‘Internet Protocol Version 6 (TCP/IPv6)’ and enable it.
   

Hope it helps.

Let us know if you got the help you needed by clicking ‘Yes’ or ‘No’.
