Although it doesn't happen all the time I've notice the more often than I'd like my router loses wi-fi. At the same time I cannot login to the admin interface of the router. As I mostly use a wired network I can often miss the fact that this has happened especially since I have a couple of wireless access points in my home that are connected via a wired connection to the router. The only solution is to reboot the router which isn't really satisfactory.
Has anyone got any idea what's the cause or is it a sign that the router is gradually failing?
