linksys wireless router setup software download

Where can I download a Linksys Wireless N router setup configuration?

So i have a mini laptop [doesnt take cd's] and i need to configure my router.
I used to have a desktop [where i installed originally] but it’s at the shop getting fixed at the moment.
for some reason my router lost its configuration and now it’s public so anyone can use it.
can i download the software?
