using mob phone connected to i/net via public wifi to connect laptop


Hi, recently purchased new laptop with windows 10 installed. I currently use public/open wifi connection to connect to the internet for non private surfing (private matters dealt with via payg dongle). However, this open wifi connection can be erratic (whereas previous laptop running windows 7 connected as and when requested). Once connected, it is faultless and speedy enough for my needs. I have also marked this connection as ‘automatic’.
I know that it is not the signal strength, it is simply the initial connection, with which my new laptop seems to struggle with! My screen shows all available networks so is picking up all correct signals. When I click ‘connect’ it will go through the motions for approx 2-3 seconds and then say ‘unable to connect to this network’ and other times, it will say ‘connecting’ and will go through these motions, and will continue to say ‘connecting’ for 15 minutes and longer or until I get sick of waiting!
On the occasions when it does finally ‘connect’, it will begin with a message in the ‘action centre’ saying ‘click on message to connect to open wifi’-it will then go to the open/public wifi homepage and connect-from thereon, I am fine.
Why won’t my laptop connect as easily to open wifi as last machine did on windows 7, and why does it continually say ‘unable to connect to internet’ or remain in ‘connecting’ mode?
A further query I have (apologies) is when my laptop refuses to connect to internet as above, my mobile phone connects to the open wifi easily so I certainly know that it is not the distance that is in question, or the strength of signal-bearing this in mind, is it possible to connect my laptop and mobile phone via usb and possible to use my phone when it is connected to the open wifi source to connect my laptop to internet via this route? If so, would somebody give me step by step instructions to connect this way, please. The phone I currently have is a 3g sony xperia mini pro (which I am sure you can gather I have had for few years now!)
Many thanks for all replies and all assistance is gratefully received.

 

laptop cant connect or stay connected to internet

And please do check that is the connection problem is occurring with that specific WiFi router or with others too? Try to connect using different router, and if you don't have a router try connecting it to WiFi hotspot and test it.
I had that problem when my old-router stopped working I replaced it with new one and in a day my laptop HP-450 was unable to connect to it whereas all other devices were connected. At first I had the same feeling that my laptop was not working and tried every thing but nothing worked. Then I tried connecting to my WiFi hotspot and it worked even in long range. Then I called Dlink and got it replaced. With the new router I had no problems.
Also do check the number of devices connected.

 

WiFi connect?

Using Windows 10 19041.630; Dell XPS13 laptop.

The area I've seen referred to as the quick options tray has an icon on it labeled "connect". Clicking that opens a menu that is headed "Searching for wireless display and audio devices". In a bit I see listed my Roku device and my Samsung TV set. Choosing the TV set, I get displayed (on the TV screen) a choice to connect. If I agree, my computer screen is displayed on the TV.

What is this service called? Is it WiFi direct connect - that is, the WiFi of my laptop connects to the WiFi of my TV set, without a router in the middle? Is it the same as Miracast? Is this connection method widely used?
