Let's do some basic checks:
1. What does the wireless icon in the system notification area (the right side of the taskbar) say when you hover your mouse above it?
2. Go into the command prompt. Type ipconfig (+enter). What's your ip-address? What's the gateway? Also note your mac-address.
3. Also from the command prompt, ping the gateway. What is the result?
If these tests succeed, you're connected to WiFi.
If not, reset the router.
If still not, try a different router. After all, it works with other routers, so why not with a replacement at home?
Couldn't connect to wi-fi at home one day, several days of troubleshooting with nothing working ultimately ending up in me doing a full factory reboot. still can't connect to home wi-fi, but can connect to mobile hotspot and public wi-fi. Three other devices in the house can connect to wi-fi no problem. been trying for days with every fix i can find on the internet; system restore, proxy settings, flush DNS, updating drivers, internet settings rest, factory reboot..... Don't understand how factory reboot didn't solve the problem! anyone any ideas???? Troubleshooting the connection either gives me "the DNS serves isn't responding" or sometimes "the remote device or resource won't accept the connection"
