how do i have reset my trenda router without a disk??tnx
There is usually a reset button, recessed into the case so it can't be pressed by accident. Use a pen tip or similar to hold that button down for ten seconds and the router will go back to the way it was when it left the factory.
Only do this if you're sure you have any ISP specific login detail you might need to re-establish a connection. Our Sticky Post to which Emerald linked in Post 2 will help you set it up again.
