Windows 7: Cannot connect to wifi: 'Windows was unable to connect to [SSID]'

Cannot connect to wifi: 'Windows was unable to connect to [SSID]'

Hi there

1. Wireless issue.
2. ISP: BT.
3. DSL connection.
4. Router: BT Smart Hub.
5. Anti-Virus S/W: AVG.

I have been unable to connect to any wifi for some weeks. My machine is a Dell Inspiron 15 1570 laptop.

The router and wifi works fine for other devices.

I have used the MS Windows 7 support forum (and others) which recommends the Windows network troubleshooter and then a series of steps after this. None have worked (although have not updated any network adapter driver).

Nwk Adapter is:
Realtek RTL8168

Device Manager reports the network adapter is working ok, although I have not been able to prove this another way. (Device Manager screenshot attached).

I have tried to connect to the Router with security switched off -no joy.

ip config file is attached.

Have run out of ideas on how to isolate the root cause of this failure to connect... ideas and advice please.

You have a valid connection to the router. What happens when you try to connect to the dchp server? Try typing this ipaddress into your browser.

DHCP Server . . . . . . . . . . . :

Please run an ipconfig /all from a working computer and post the results. Also try this guide. Fix

W7 home premium 32bit/W7HP 64bit/w10 tp insider ring

Both of the reports, show that IPV4 is NOT turned on
BT doesnt use IPV6 so you need IPV4

note installed drivers is showing an Avast driver not AVG, you can uninstall it
