Internet not connected through wifi but no problem through Ethernet

[hellytangse]

I have just had a new wifi router installed. Tab and phone connect through wifi to the internet fine, Laptop doesn't - I get the yellow triangle. Having searched online for solutions I have:
1) checked TCP/IP and DNS are automatically obtained.
2) Uninstalled AVG antivirus
3) disabled and enabled the wireless adapter
4) unplugged and plugged in the route

But none of these have solved the issue. The results of IpConfig when connected through the ethernet are:

The result wifi is connected:
