why can't I connect to the Internet anymore?

[Jay_45]

I recently upgraded to Windows 10 but couldn't connect to the Internet even though I was connected to the wifi in my house. So I reverted back to Windows 7. I have Windows 7 again but now every time I try to open a webpage it says the the proxy server is refusing connections, even though im connected to the wifi in my house. I just got online the day before. What can I do to fix this?

Ok so this would be a Driver issue. If you are using a Desktop go to the website that the Wireless card or Ethernet port is made by and search for your product. Then download the drivers onto a USB on another computer and install them into the pc you are trying to fix. If this is a Laptop then go look up the laptop on another computer and do the same. If you have a PC and the Ethernet port is on the motherboard then look up the motherboard on the suppliers website and download the driver from there.

if that above dosent fix your problem, try opening internet options, going to connections, click on LAN connections. make sure its set to automatically retrieve settings and not set to proxy.

1. CMD => ipconfig /all
Make sure the IPv4 address, subnetmask and default gateway are there (you should get those from router due DHCP)
2. ipconfig /flushdns or set DNS as DHCP aswel
3. See if you can ping your router (default address should be 192.168.1.1 or 192.168.0.1)
4. Restart modem/router, see if cable is plugged in well
