If the iPhone is not connecting I'd try a hard reset if the push button method fails or is not supported.
Your post left out the modem/router make/model.
I have a Toshiba, Qualcomm Atheros AR956x wireless network, Windows 10 and this is the first time I cleaned my laptop since I got the laptop 9 months ago. I did 8 hours ago with ccleaner (both the cookies, registry, free space) and also scanned for virus with avast. I've always had avast installed since I got my laptop.
Afterwards, I was able to connect to the Internet. 2 hours ago, I changed r
the password to my hotspot and it just won't connect anymore. I'm connecting via my iPhone hotspot. I have been using my hotspot and my laptop for more than 9 months without any problem. Each time I try to connect, I see that it is trying to connect but breaks off(I know because at that point, my antivirus connect for a second and drop off).
Please can someone help me? I am not a computer guru, I don't even know what to do or where to go to in the computer. I tried to forget the network and reconnect, I rebooted my laptop and iPhone but it's not working. I checked various forum to see if someone's situation fits mine- from a forum, I saw a comment to check your ipconfigure on run, I did, it says media disconnected.
Please I need help.
