We have a Linksys WRT120N in our apartment and it keeps dropping the wifi, requiring sometimes multiple restarts per day. Before I buy a new one, I wanted to try updating the firmware, as it is out of date. I downloaded the .bin file from the router's web page, and loaded it in the Administration tab of the router setup web page, but when I click the "Start to upgrade" button, I get a page that says 403 Forbidden: Your client does not have permission to get this page.from this server. A google search yielded no help, so I've turned here. Any ideas how to fix this?
