Windows 10: WiFi

I recently upgraded to windows 10. i started having a series of problems but they eventually fanned out but I still am unable to connect to the internet via wifi. I have to use the ethernet cable.

:)

 

No more WIFI. What?

My Samsung Focus Flash, a Windows Phone no longer recognizes WIFI networks . WIFI turned on but the screen just keeps saying "Searching". Other devices I have recognizes my WIFI network.



Told to do a hard reset. What happens if I do device reset? What do I lose? Do I have to buy previously purchased apps? What about contacts?

 

Windows 10 WiFi not working after sleep mode

I've seen some older posts with this issue, but none every really say what the fix is. Seems this typically gets fixed by messing around in the systems and some unknown action fixes the issue. I've not been so lucky. So, problem is; I have a new Dell
Inspiron 13 7000 series, i5 with Windows 10. My Wifi connects and works fine. If the computer goes to sleep, or the screen saver comes on, when I wake it back up the Wifi says it's "connected", but it does not work. If I hover over the WiFi icon in the lower
right it says "no internet connection". I can disconnect and reconnect to Wifi, but it still will not work. If I totally restart the computer, WiFi automatically connects and it's all good until next time it sleeps or the screen saver comes on and I wake
the system back up. I've unchecked the box in Device Manager power settings that allows/prevents the WiFi to be turned off in power saving mode. Anyone know how to fix this?

I have 2 laptops.
One is a Dell which has a switch at the front to turn On or Off WiFi.
One is an Acer Aspire. It has a F3 key which is also used to switch on or off WiFi.

Have a look at your computer manual ,hopefully you still have it.
