Windows 10: I have experienced intermittent 4G network dropped off in my laptop

My laptop brand is Lenovo , and I have tried in different models and they all have similar issues, so it is very likely the issue is from OS.Sometimes it shows " please insert sim" , sometimes it shows " cannot connect to this network, Mobile data is not working properly, try again later."This issue could be resolved by either restart, or reinstall driver manually.- this rule out hardware faultsThe APN setting was selected to be managed by Windows .My laptop has been applied the latest OEM drivers officially from manufacture, I am running Windows 11 now, however, the same issue did also occur

Wireless network drops intermittently, needs reset to reconnect

I noticed a strange (puzzling!) but extremely interesting phenomenon during a video conference call this morning.

1. The network dropped as usual, at some time during the video call.
2. But the video call using Zoom.us, *did not drop!*. That's right - the 1 hour of network down time did not affect the Zoom.us video call at at.
3. But other services, specifically, web browser-based services reported no network. I all my browsers - Chrome, Edge, FF - I could not connect to any websites. Also, I have "pseudo-web apps" running, such as WhatsApp's desktop app (which seems to be a shell around a browser), all of which seemed unable to connect. Google Hangouts could not connect either.
4. Weirdly, another collaboration desktop app that I used - Slack - was able to *partially connect!*. That is, I was able to send and receive messages on Slack while the network was out for the hour, but Slack *still* reported no network connection (weird!).

It leads me to believe (and I could be wrong), that *some* parts of the network seem to go down and not come back up until they wireless connection is reset. Maybe some ports, like 80/8080/465/587/110/... are being shut down?

Any ideas?

 

Wireless network drops intermittently, needs reset to reconnect

From my previous detailed comment (Wireless network drops intermittently, needs reset to reconnect - Page 4 - Windows 10 Forums), you might surmise that the problem isn't with the wifi adapter or router.

Also because this laptop is the only one that is behaving this way. Other Windows 7 and Mac laptops and smartphones connected to the same network are fine.
