My friend has had issues with wifi connections on and off since upgrading to Windows 10.
I was able to fix this for her by changing her IPv6 settings to a set internal IP and DNS etc. Then the problem happened again and i switched it back to detect automatically which worked. And then, after a while, it happened again etc
I THINK the last settings we inputted and were not detecting automatically.
Anyway, the same issue arose last night and I was trying to talk her through changing the settings via messages and phonecall but was having difficulty, so when i came across instructions to run via command prompt, i thought that might be easier to instruct. So she did that, but since then the laptop won't respond. She said it was shutting itself down, but don't know if she had instigated that as per instructions. I asked her to try and force shutdown but she said it still wasn't working but i don't know if she managed to get it to shut down.
I'm thinking that Windows has cr@pped itself because DNS settings were wiped yet option to detect automatically wasn't selected? Is there anything I can do? I won't get a chance to look at it until later. See pics attached
