Release and renew your DHCP address - perhaps that will reset the correct DNS server.
IPCONFIG /RELEASE, then do IPCONFIG /RENEW.
If that fails, try setting the DNS server entry into your PC manually - 192.168.0.1, as per the laptop.
Please do a ping to
www.pprune.org from a command window - the key question is whether or not it resolves the name to an IP address.
