My sister has a sony vaio with Windows Vista. This laptop cannot connect to the Internet since last month, before that it worked properly. I don't know why it always has IP begin with "169." while the IP of the Netcomm router is "192.168.". (for both wireless and local network connection) I try to release thi IP but receiving a message " the operation needs elevation". When I assigned IP manualy, the connection is just "local only".
I have a IBM laptop, it can connect to the internet through the Netcomm router above but with manual IP, it means I cannot use DHCP to assign automatic IP.
To release the IP in Vista , go to ...start/programs/accessories/command prompt , right click and select " run as administrator " then you will have the necessary privileges . Sounds like a reboot of the router is in order after checking whether DHCP is enabled but it is not giving IP addresses .
I cannot ping the router's IP address The vaio see the wireless network with warning "unidentified network". I tried to release IP address as Ashrich said but receive "the IP has not yet associated with the endpoint".
Have you tried a full reboot of the router , holding a unbent paper clip into the little hole on the back , for about 20 to 30 seconds . When you take the pin out the router will go through it's set up routine again , and re-synchronise with the exchange , hopefully you should be able to log in to the routers set up pages and re-enter all your login data and actually connect to the internet , then try connecting through wireless again , first , and just to test , try it without any safety encryption and no firewalls , if it works try adding WPA security , if that's Ok restart the firewall .
