IP Adress not renewing overnight
 

Sony Vaio with built in Wi-Fi. Networked with a wired computer on Netgear
WR614. Setup worked fine for months and then I decided to try to add some
security and played with setting on router setup. Have gone back to the
basic unsecured version. Now in the morning the wired version connects fine
but the wireless version does not connect until I click refresh on the
Windows properties box. When I run "Repair" it comes back and says "Unable
to renew IP address" Any suggestions where to go (no pun intended) for a fix
Regards,
David
